Question 1Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

In Delaware, what does a red octagonal sign with the word STOP require a driver to do?

  1. Stop only if other traffic is approaching the intersection
  2. Come to a complete stop before the stop line or crosswalk, then proceed when safe Correct answer.
  3. Slow to about 10 mph and continue if the intersection looks clear
  4. Yield the right of way without stopping when no vehicles are present

Explanation

A STOP sign requires a full halt at the marked stop line, at the crosswalk, or at the edge of the intersecting roadway if neither is marked. The driver then yields to cross traffic and pedestrians before proceeding. Rolling through the sign or stopping only for visible traffic violates the requirement.

Question 2Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

What is the required action when a driver approaches a YIELD sign?

  1. Slow down and give the right of way to traffic on the intersecting road Correct answer.
  2. Stop completely, then accelerate through the gap
  3. Maintain speed because the other road must wait
  4. Sound the horn before entering the intersection

Explanation

A YIELD sign means the driver must slow and let crossing traffic, and any pedestrians, pass before entering or merging. A complete stop is required only when necessary to avoid conflict. Yielding does not transfer the right of way to the driver with the sign.

Question 3Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A white rectangular sign shows a black left-turn arrow crossed by a red circle with a diagonal slash. What does it mean?

  1. A left turn lane opens ahead
  2. Left turns are permitted only during green arrows
  3. Left turns are prohibited at this location Correct answer.
  4. Left turns must be made from the center lane

Explanation

A red circle with a diagonal slash is the universal prohibition symbol, so an arrow inside it marks a maneuver that is not allowed. Here the banned maneuver is turning left. The sign does not create a permitted turn window or describe lane geometry.

Question 4Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

What does a black-and-white sign reading SPEED LIMIT 25 indicate in Delaware?

  1. The maximum lawful speed under normal conditions Correct answer.
  2. The speed enforced only during school hours
  3. The minimum speed for the roadway
  4. A suggested speed for wet conditions

Explanation

A regulatory SPEED LIMIT sign sets the maximum lawful speed for that section of road in normal conditions. Drivers may lawfully travel slower when conditions require. Advisory or conditional speeds are posted with different sign designs.

Question 5Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A white sign with a red circle and slash over a letter P means a driver may:

  1. Park only with a permit displayed
  2. Park only during daylight hours
  3. Park for a limited time shown on the sign
  4. Not park at that location at any time Correct answer.

Explanation

The red circle with a diagonal slash over a P marks a no-parking zone. Parking there is prohibited whenever the restriction applies. Permit or time-limit parking uses different sign designs without the prohibition symbol.

Question 6Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

What does a white rectangular sign displaying a single black arrow curving to the right indicate?

  1. A lane that must be used for right turns
  2. A one-way street begins ahead
  3. A sharp curve warning for the roadway
  4. A right turn is required ahead Correct answer.

Explanation

A white regulatory sign with a single directional arrow and the word ONLY, or an arrow indicating a mandatory movement, directs traffic to proceed in that direction. A right-curving arrow on a regulatory sign means drivers must turn right. Warning signs for curves are yellow diamonds.

Question 7Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A sign reading NO RIGHT TURN ON RED is posted at an intersection. What does it require?

  1. Drivers must wait for a green arrow before turning right Correct answer.
  2. Drivers may never turn right at this intersection
  3. Drivers must turn right only from the left lane
  4. Drivers may turn right after stopping only if no pedestrians are present

Explanation

Delaware generally allows a right turn on red after a full stop unless a sign prohibits it. Where the prohibition sign is posted, the driver must remain stopped until the signal gives a lawful green indication for the turn. The restriction applies to the red phase, not to every right turn.

Question 8Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

Which sign shape is used exclusively for regulatory railroad crossing restrictions such as a stop requirement at tracks?

  1. White X-shaped crossbuck with a stop plaque
  2. White vertical rectangle with black lettering Correct answer.
  3. Yellow diamond with a circular symbol
  4. Round yellow sign

Explanation

Regulatory messages, including a requirement to stop at railroad tracks, are conveyed on white vertical rectangles with black lettering and are enforceable. The round yellow sign is an advance warning of tracks ahead. The crossbuck marks the crossing itself.

Question 9Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver approaches a steady red left-turn arrow at an intersection in Delaware. What is the correct action?

  1. Turn left after yielding to oncoming traffic
  2. Proceed because left turns are always permitted on red
  3. Turn left if the through light is green
  4. Wait behind the stop line until a green arrow appears Correct answer.

Explanation

A red arrow is a lane-specific signal that prohibits the indicated movement. The driver must stop and wait for the arrow to turn green before turning. A green through light does not authorize a left turn when the left arrow remains red.

Question 10Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A white sign marks a lane with the word ONLY beneath a left-turn arrow. A driver in that lane intends to continue straight. What must the driver do?

  1. Stop and wait for a gap to merge left at the crosswalk
  2. Change to a through lane before reaching the intersection Correct answer.
  3. Proceed straight but yield to left-turning vehicles
  4. Continue straight from that lane because arrows are advisory

Explanation

A turn-only lane designation is regulatory: vehicles in that lane must make the indicated movement. A driver who wants to go straight must move into a through lane before the intersection. Continuing straight from a turn-only lane is a violation and can conflict with other traffic.

Question 11Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A yellow diamond sign shows a black arrow bending sharply left above the number 25. How should a driver interpret it?

  1. The curve is 25 feet ahead
  2. A 25 mph advisory speed applies to the upcoming curve Correct answer.
  3. The speed limit is 25 mph through the curve
  4. Trucks must reduce speed to 25 mph

Explanation

A yellow diamond is a warning sign, and a speed plaque beneath a curve warning gives an advisory speed for that curve. The advisory speed reflects conditions rather than the legal maximum, though traveling faster may be unsafe and can support a citation for driving too fast for conditions. The number does not measure distance.

Question 12Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver parks at a metered space beside a sign reading NO PARKING 7 AM TO 9 AM MONDAY THROUGH FRIDAY. It is 10 AM on Wednesday. What is true?

  1. Parking is allowed only for 30 minutes
  2. Parking is prohibited because Wednesday is a weekday
  3. Parking is prohibited because the sign applies all day
  4. Parking is allowed if the meter is paid, since the restriction has ended for the day Correct answer.

Explanation

Time-limited parking restrictions apply only during the posted hours and days. Outside that window, such as 10 AM on a Wednesday, the restriction no longer bars parking, though other rules such as meters or permit zones may still apply. The sign's day list defines when the ban operates, not a blanket weekday ban.

Question 13Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A white rectangular sign reads KEEP RIGHT WITH TRAFFIC ISLAND. What does it direct a driver to do?

  1. Drive over the island if no traffic is present
  2. Turn right immediately at the island
  3. Stop before the island and wait for a gap
  4. Pass the traffic island on its right side Correct answer.

Explanation

A KEEP RIGHT sign is a regulatory direction to pass a median, island, or obstruction on the right side. Driving to the left of the island would put the vehicle in opposing or restricted space. The sign does not require stopping or turning.

Question 14Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver sees a white sign reading DO NOT PASS with a black symbol of two cars. On a two-lane road, what does this sign mean?

  1. Passing is prohibited only at night
  2. Passing is discouraged but allowed when the road is clear
  3. Only trucks may not pass in this zone
  4. Passing other vehicles is prohibited in this zone Correct answer.

Explanation

A DO NOT PASS sign is a regulatory sign that prohibits passing in the marked zone, typically because of limited sight distance or a hazard. The restriction applies to all vehicles and at all hours unless a plaque states otherwise. Passing in a no-passing zone is a moving violation.

Question 15Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A white sign reads NO U-TURN. A driver who missed a turn wants to reverse direction. What is the lawful option at that location?

  1. Continue to a location where a U-turn is permitted Correct answer.
  2. Make a three-point turn in the roadway instead
  3. Make the U-turn from the left lane only
  4. Make the U-turn if no traffic is visible

Explanation

A NO U-TURN sign prohibits reversing direction at that location regardless of traffic conditions. The driver must continue until reaching a place where the maneuver is legal, such as a permitted intersection or a driveway loop. Substituting a three-point turn does not satisfy the restriction.

Question 16Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A sign shows a white left-turn arrow with the word ONLY, and the pavement in that lane is marked with a left-turn arrow. What do the sign and marking together establish?

  1. The lane is reserved for left turns, and through travel from it is prohibited Correct answer.
  2. The lane is a shared through and left-turn lane
  3. The lane may be used for through traffic when the arrow signal is green
  4. The lane is for buses making left turns

Explanation

When a regulatory sign and pavement markings both designate a lane for left turns only, the lane is reserved for that movement. A driver who enters it must turn left. Through travel from a turn-only lane is a violation even if the signal is green.

Question 17Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver is traveling 40 mph in a posted 35 mph zone and passes a sign reading SPEED LIMIT 35. Which statement best describes the legal position?

  1. The driver is lawful because speed limits are advisory
  2. The driver is lawful because limits allow a 10 mph tolerance
  3. The driver is speeding only if a police officer observes the violation
  4. The driver is speeding because the posted limit is the maximum lawful speed Correct answer.

Explanation

The posted speed limit is the maximum lawful speed under normal conditions, so traveling 40 mph in a 35 mph zone exceeds the limit. Enforcement tolerances are administrative practices and do not change the legal maximum. Speed limits are regulatory, not advisory.

Question 18Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver approaches a YIELD sign at a freeway on-ramp with traffic already on the mainline. What is the safest lawful action?

  1. Enter the mainline and then adjust speed to fit traffic
  2. Accelerate to match mainline speed and merge when a safe gap exists, yielding to mainline traffic Correct answer.
  3. Maintain ramp speed and expect mainline drivers to change lanes
  4. Stop at the end of the ramp and wait for a complete gap in all lanes

Explanation

At a YIELD sign on an on-ramp, the merging driver must give way to mainline traffic. The appropriate technique is to use the ramp to build speed matching the mainline and merge into a safe gap. Stopping at the end of the ramp creates a hazard and is unnecessary when a gap is available.

Question 19Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A white sign reads NO PARKING ANY TIME, and a separate plaque below reads EXCEPT SUNDAYS. How does the exception apply?

  1. Parking is allowed on Sundays, subject to any other posted restrictions Correct answer.
  2. Parking is prohibited on Sundays only
  3. Parking is allowed every day except Sundays
  4. The plaque cancels the no-parking rule entirely

Explanation

An EXCEPT plaque narrows the restriction to which it is attached, so the no-parking rule does not apply on Sundays. Other rules, such as meters, fire lanes, or permit zones, may still restrict parking that day. The plaque does not eliminate the restriction on other days.

Question 20Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver is in a lane marked with a white sign showing a straight-through arrow and the word ONLY, but wants to turn right at the next intersection. What is the correct course of action?

  1. Stop in the through lane and wait for permission to turn
  2. Turn right from the through-only lane after signaling
  3. Turn right from the through lane only if no vehicles are behind
  4. Change to a right-turn lane before the intersection if one is marked Correct answer.

Explanation

A through-only lane designation requires vehicles in that lane to continue straight. A driver who needs to turn must move into the appropriately marked turn lane before the intersection. Turning from a through-only lane violates the lane designation and can cause conflicts.

Question 21Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver approaches a STOP sign at a four-way intersection at the same moment as a vehicle on the right. Both arrive simultaneously. Who has the right of way?

  1. The driver who arrives first, and if simultaneous, the vehicle on the right Correct answer.
  2. The driver traveling on the wider road
  3. The driver who signals first
  4. The driver in the larger vehicle

Explanation

At an all-way stop, the first vehicle to arrive and stop has the right of way. If two vehicles arrive at the same time, the driver on the left yields to the vehicle on the right. Road width, signaling, and vehicle size do not determine priority.

Question 22Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A white sign marks a two-way left-turn lane in the center of a roadway. Which use of that lane is lawful?

  1. Traveling in the lane for up to 200 feet to pass slower traffic
  2. Using the lane to begin or complete a left turn from either direction Correct answer.
  3. Using the lane to make a U-turn at any point along it
  4. Parking briefly in the lane to load passengers

Explanation

A two-way left-turn lane is reserved for vehicles preparing for or completing left turns from either direction. It is not a travel, passing, or parking lane. Drivers enter it only shortly before turning and must yield to any vehicle already using it.

Question 23Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver on a one-way street encounters a sign reading NO LEFT TURN. The driver needs to go left. What is the correct interpretation?

  1. The turn is allowed because the street is one-way
  2. The left turn is prohibited, so the driver must find another lawful route Correct answer.
  3. The sign applies only to traffic coming from the opposite direction
  4. The sign prohibits only trucks from turning left

Explanation

A NO LEFT TURN sign prohibits the left turn for traffic facing it, regardless of the street's one-way status. The driver must continue and find a lawful way to reach the destination. The sign is not limited by vehicle type or by the direction of other traffic.

Question 24Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver passes a SPEED LIMIT 55 sign and then, a short distance later, a sign reading END 55 MPH ZONE. What does the second sign indicate?

  1. The maximum speed becomes 55 mph from that point
  2. Drivers must reduce speed to 55 mph immediately
  3. The previously posted limit no longer applies, and the default or next posted limit governs Correct answer.
  4. The road becomes a 55 mph minimum speed zone

Explanation

An END sign terminates the restriction it names, so the 55 mph zone no longer applies beyond that point. The default statutory limit or the next posted limit then governs the roadway. The sign does not create a new 55 mph requirement or a minimum speed.

Question 25Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver is stopped at a red light in a lane marked with a white left-turn arrow and ONLY. The through light turns green, but the left arrow remains red. What may the driver lawfully do?

  1. Turn left because the through light is green
  2. Turn left after yielding to oncoming traffic
  3. Wait for the left arrow to turn green before turning Correct answer.
  4. Proceed straight from the turn-only lane

Explanation

The red left arrow controls the turn-only lane and prohibits the left turn until it changes. A green through light authorizes through traffic in through lanes, not a left turn from a turn-only lane. Yielding to oncoming traffic does not override a red arrow.

Question 26Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A Delaware driver sees a white rectangular sign reading SPEED LIMIT 45. What does this sign establish on that stretch of road?

  1. The maximum lawful speed under normal conditions Correct answer.
  2. An advisory speed recommended for curves only
  3. The speed limit that applies only to trucks
  4. A minimum speed that all traffic must maintain

Explanation

A white rectangular SPEED LIMIT sign is regulatory and sets the maximum lawful speed for that roadway under favorable conditions. Drivers may lawfully travel slower when conditions or caution require it. The posted number is not a minimum, an advisory curve speed, or a truck-only limit.

Question 27Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver approaches an intersection where a red octagonal sign is posted. What must the driver do before proceeding?

  1. Come to a complete stop, then yield to traffic and pedestrians with the right of way Correct answer.
  2. Slow down and continue if the way looks clear
  3. Yield only to vehicles approaching from the left
  4. Stop only when other vehicles are present

Explanation

The red octagon is the STOP sign, and it requires a full stop at the marked line or before entering the crosswalk. After stopping, the driver yields to pedestrians and to traffic that has the right of way. A rolling slowdown does not satisfy the requirement.

Question 28Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A triangular sign with a red border and white center is posted at the entrance to a Delaware intersection. What does this sign require of an approaching driver?

  1. Maintain speed because the sign applies only to trucks
  2. Come to a complete stop before entering
  3. Slow down and give the right of way to cross traffic and pedestrians Correct answer.
  4. Merge without adjusting speed because the other road must yield

Explanation

The downward-pointing triangle with a red border is the YIELD sign. It requires the driver to slow and, if necessary, stop to let cross traffic and pedestrians with the right of way pass. Traffic on the favored road is not required to yield to the entering driver.

Question 29Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A white rectangular sign shows a black arrow pointing straight ahead with a diagonal red slash through it. What does this sign tell a driver?

  1. Straight-through traffic has the right of way
  2. Straight-through movement is prohibited at this location Correct answer.
  3. The road ahead is closed for construction
  4. Only trucks may continue straight

Explanation

A white regulatory sign with a movement arrow crossed by a red slash prohibits that movement. Here the straight-ahead arrow is barred, so drivers must turn rather than continue through. The sign does not grant priority, announce construction, or restrict the movement to trucks.

Question 30Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A white sign mounted in a parking area reads NO PARKING ANY TIME. What does this sign mean for a driver?

  1. Parking is allowed briefly if the driver stays in the vehicle
  2. Parking is prohibited only during business hours
  3. Parking is allowed on weekends only
  4. Parking is prohibited at all hours, including short stops to load passengers Correct answer.

Explanation

NO PARKING ANY TIME is an absolute restriction that applies around the clock, with no time window and no brief-stay exception. A driver may not leave the vehicle parked there at any hour. Loading or waiting in the space is likewise not permitted.

Question 31Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver sees a white sign reading ONE WAY with an arrow pointing to the left. What does this sign indicate about the roadway ahead?

  1. The roadway is closed to traffic beyond the sign
  2. All traffic on that roadway moves only in the direction of the arrow Correct answer.
  3. Traffic may travel in either direction but must keep left
  4. The left lane is reserved for turning vehicles

Explanation

The ONE WAY sign with an arrow tells drivers that all traffic on that roadway flows in the direction the arrow points. Entering against the arrow would mean driving into oncoming traffic. The sign does not describe a two-way road, a turn lane, or a closure.

Question 32Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A white rectangular sign displays a black arrow curving left with the word ONLY beneath it, mounted over a specific lane. What does this sign mean for drivers in that lane?

  1. They may turn left or continue straight at their option
  2. They must turn left at the upcoming intersection Correct answer.
  3. They may turn left only when a green arrow appears
  4. They must merge left into the adjacent lane

Explanation

A lane-use sign showing a turn arrow with ONLY designates that lane exclusively for the shown movement. A driver who enters the lane is committed to turning left. Continuing straight or merging out of the lane would violate the lane designation.

Question 33Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A white sign reading DO NOT ENTER is posted at the end of a roadway. What does this sign mean for a driver approaching it?

  1. The driver must not proceed past the sign into that roadway Correct answer.
  2. The driver may enter only to turn around
  3. The driver may enter if no oncoming vehicles are visible
  4. The driver must stop and then may continue

Explanation

DO NOT ENTER marks a roadway that may not be entered, typically because traffic there flows toward the driver. Proceeding past the sign would put the driver against the flow of traffic. Visibility of oncoming vehicles does not make entry lawful.

Question 34Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver on a Delaware two-lane road passes a white sign reading SPEED LIMIT 35 with a plaque below reading TRUCKS 25. How do the two limits apply?

  1. Both limits are advisory and may be exceeded in light traffic
  2. Trucks may travel up to 35 mph while cars are limited to 25 mph
  3. Passenger cars may travel up to 35 mph while trucks are limited to 25 mph Correct answer.
  4. All vehicles must travel 25 mph

Explanation

A lower limit on a separate plaque applies to the vehicle class named on that plaque. Here trucks are capped at 25 mph while other vehicles retain the general 35 mph limit. Both numbers are regulatory maximums, not advisory speeds.

Question 35Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver is stopped at a STOP sign and wants to turn right onto a road where a red light is controlling the cross traffic. Pedestrians are crossing in the marked crosswalk to the driver's right. What is the correct action?

  1. Sound the horn so the pedestrians hurry across
  2. Wait for the pedestrians to clear, then turn when the way is safe Correct answer.
  3. Turn immediately because the driver has already stopped
  4. Turn and pass behind the pedestrians within the crosswalk

Explanation

After stopping at a STOP sign, the driver must yield to pedestrians in the crosswalk and to cross traffic before completing the turn. Pedestrians in a marked crosswalk have the right of way. Passing behind them within the crosswalk still conflicts with their path.

Question 36Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver approaches a YIELD sign on a side street that merges into a busy arterial. Traffic on the arterial is continuous. What must the driver do?

  1. Proceed and expect arterial traffic to slow for the merging vehicle
  2. Stop completely and remain stopped until the arterial clears of all vehicles
  3. Enter the arterial at speed because the YIELD sign gives priority
  4. Slow or stop as needed and wait for a safe gap in arterial traffic Correct answer.

Explanation

A YIELD sign obliges the driver to let traffic on the favored road pass and to enter only when a safe gap exists. The driver may need to stop, but a permanent stop is not required once a gap opens. Arterial traffic has no duty to yield to the merging driver.

Question 37Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver in a lane governed by a sign showing a left-turn arrow and ONLY decides mid-block to continue straight through the intersection instead. What is the status of that action?

  1. Lawful if no left-turning vehicles are waiting
  2. Lawful because the sign is advisory only
  3. Lawful if the driver signals before the intersection
  4. Unlawful because the lane is dedicated to left turns Correct answer.

Explanation

A lane marked with a turn arrow and ONLY is dedicated to that movement, and proceeding straight from it violates the lane-use regulation. The restriction does not depend on whether other vehicles are present. An advisory sign would be yellow, not white with ONLY.

Question 38Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver parks beside a sign reading NO PARKING 8 AM TO 6 PM MONDAY THROUGH FRIDAY. It is 7 PM on a Tuesday. What is the status of parking there?

  1. Parking is permitted only for loading and unloading
  2. Parking is prohibited until the next morning
  3. Parking is prohibited because the day is a weekday
  4. Parking is permitted because the restriction has ended for the day Correct answer.

Explanation

The sign restricts parking only within the stated hours on the stated days. At 7 PM on a Tuesday the daily window has closed, so parking is allowed until the restriction resumes. The weekday itself does not extend the prohibited period.

Question 39Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver traveling on a one-way street meets a white sign reading NO LEFT TURN at an intersection. The driver's destination lies to the left. What is the lawful approach?

  1. Continue ahead or take another permitted route to reach the destination Correct answer.
  2. Turn left only if a police officer is not present
  3. Make a U-turn to approach from the other direction
  4. Turn left after stopping and checking for traffic

Explanation

A NO LEFT TURN sign bars the left movement entirely, so the driver must find a permitted route, such as continuing ahead and circling back. The restriction is not waived by stopping or by the absence of enforcement. A U-turn may itself be separately prohibited and is not a substitute for the barred turn.

Question 40Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver passes a sign reading END 25 MPH ZONE and, farther ahead, sees no other speed posting. What speed limit now governs the roadway?

  1. 25 mph continues until another sign appears
  2. The statewide default or previously posted limit for that road applies Correct answer.
  3. There is no speed limit until the next sign
  4. The driver may choose any safe speed

Explanation

An END plaque terminates the special zone limit, and the roadway reverts to its underlying limit, which may be a statewide default or an earlier general posting. The reduced number does not persist once the zone ends. Some lawful maximum always applies.

Question 41Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver enters a center lane marked on both sides by solid yellow lines and signs showing left-turn arrows for both directions. What use of this lane is lawful?

  1. Making a left turn into or out of adjacent driveways and side roads Correct answer.
  2. Parking briefly while making a delivery
  3. Using it as a through lane during heavy congestion
  4. Driving in it for long distances to pass slower traffic

Explanation

A two-way left-turn lane is reserved for left turns into and out of the adjacent roadways and driveways. It may not be used as a through travel lane or for passing. Parking in it is likewise prohibited.

Question 42Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver approaches an intersection where a steady red arrow pointing left is displayed, and Delaware law permits a left turn on red only from a one-way street onto another one-way street. The driver is on a one-way street turning left onto a one-way street. What may the driver do?

  1. Wait for a green arrow in every case
  2. Turn left only after the vehicle behind signals approval
  3. Turn left immediately without stopping because the roadways are one-way
  4. Stop, yield to traffic and pedestrians, then turn left if it is safe Correct answer.

Explanation

Where left turns on red are permitted from a one-way street onto a one-way street, the driver must first stop and yield before turning. The turn is allowed only when the way is clear of traffic and pedestrians. A green arrow is not required in that situation.

Question 43Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver sees a white sign reading KEEP LEFT with an arrow, placed ahead of a raised median. What does the sign require?

  1. Pass to the right side of the median
  2. Pass to the left side of the median Correct answer.
  3. Turn around at the median
  4. Stop before the median and wait

Explanation

A KEEP LEFT sign directs traffic to pass on the left side of the island or median ahead. It is a regulatory direction, not a suggestion. Passing on the right would put the vehicle on the wrong side of the divider.

Question 44Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver wants to make a right turn at an intersection but sees a white sign reading NO RIGHT TURN ON RED. The light is red and the driver has stopped. What does the sign require?

  1. The driver must wait for a green light before turning right Correct answer.
  2. The driver may turn right only if no pedestrians are present
  3. The driver may turn right after a full stop of at least ten seconds
  4. The driver may turn right after yielding to traffic

Explanation

NO RIGHT TURN ON RED removes the usual permission to turn right after stopping at a red light. The driver must remain stopped until the signal turns green and the turn can be made safely. Yielding or waiting a set time does not substitute for the green light.

Question 45Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver is in a lane marked by a sign showing a straight-through arrow and ONLY. The driver wants to turn right at the next intersection. What should the driver do?

  1. Continue straight and find a lawful route to the destination Correct answer.
  2. Change lanes within the intersection to reach the right-turn lane
  3. Turn right from the through lane after signaling
  4. Turn right anyway because the sign is a recommendation

Explanation

A lane marked with a straight arrow and ONLY may be used only to proceed straight, so a right turn from it is prohibited. The driver should continue straight and reroute rather than turn from the wrong lane. Lane changes inside an intersection are also improper.

Question 46Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver sees a white sign reading NO U-TURN at a median opening but needs to reverse direction. Which action is lawful?

  1. Make the U-turn if no traffic is visible in either direction
  2. Continue to a location where a U-turn is permitted and reverse there Correct answer.
  3. Back the vehicle through the opening to reverse direction
  4. Make a three-point turn across the median opening

Explanation

A NO U-TURN sign bars reversing direction at that location regardless of how light traffic is. The lawful approach is to continue to a place where the maneuver is allowed. Neither a multi-point turn nor backing through the opening is a lawful substitute.

Question 47Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver sees a white sign reading SPEED LIMIT 55 with a plaque below reading MINIMUM 40. Traffic is flowing at 50 mph in clear, dry conditions. How should the driver interpret the two numbers?

  1. The driver may lawfully travel between 40 and 55 mph Correct answer.
  2. The driver must travel at least 55 mph
  3. The driver must travel exactly 40 mph
  4. The minimum applies only to trucks

Explanation

A posted maximum and a posted minimum together define a lawful speed range. Traveling 50 mph falls within that range and is lawful in clear conditions. Neither number is a target that must be matched exactly.

Question 48Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver approaches a STOP sign at the same time as a vehicle on the left at an uncontrolled four-way stop. Both vehicles arrived simultaneously. Who has the right of way?

  1. The vehicle on the left, because it arrived first
  2. Neither vehicle may proceed until a signal changes
  3. The driver, because Delaware law gives priority to the vehicle going straight
  4. The driver, because the other vehicle is on the left Correct answer.

Explanation

At a four-way stop where vehicles arrive at the same time, the driver on the left must yield to the vehicle on the right. Here the other vehicle is on the left, so the driver has the right of way. The rule does not depend on which vehicle intends to go straight.

Question 49Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver faces a white sign showing a left-turn arrow with a red slash through it, while the through lane beside it is open. The driver's route requires a left turn at that intersection. What is the correct conclusion?

  1. The left turn is permitted after a complete stop
  2. The left turn is prohibited, so the driver must use another route or a later intersection Correct answer.
  3. The sign applies only to commercial vehicles
  4. The left turn is permitted only during daylight hours

Explanation

A movement arrow crossed by a red slash prohibits that movement for all traffic at that location. The driver must find a lawful alternative, such as a different intersection or a permitted turn sequence. Stopping, time of day, and vehicle type do not lift the restriction.

Question 50Regulatory signs (speed limits, stop, yield, lane use, turns, parking)

A driver is in a lane marked with a sign showing a left-turn arrow and ONLY, and the traffic signal for that lane shows a green left arrow while the adjacent through lane shows green. What is the correct action for the driver?

  1. Complete the left turn, since the lane and signal both authorize it Correct answer.
  2. Change into the through lane inside the intersection and continue
  3. Wait for the through lane to turn red before turning
  4. Proceed straight because the adjacent through lane has green

Explanation

The lane designation and the green left arrow both authorize the left turn, so the driver should complete it. The green display for the adjacent through lane governs that lane, not this one. Changing lanes inside the intersection is improper.
