Question 1Colorado traffic laws and rules of the road
Under Colorado law, what is the maximum speed limit on a rural interstate highway unless a different limit is posted?
- 80 mph
- 65 mph
- 70 mph
- 75 mph Correct answer.
Explanation
Colorado sets the general maximum speed limit on rural interstate highways at 75 mph, and this applies unless a lower limit is posted for a specific stretch. Posted signs always control, so drivers must watch for reduced limits through mountains, construction zones, and urban areas.
Question 2Colorado traffic laws and rules of the road
In Colorado, a driver approaching a steady red traffic signal must come to a complete stop and may then:
- treat the signal as a yield sign and slow without stopping
- proceed only after yielding to traffic and pedestrians when turning right, or turning left from a one-way street onto another one-way street Correct answer.
- proceed straight ahead if no cross traffic is visible
- remain stopped until the signal turns green in every circumstance
Explanation
Colorado follows the standard rule that a steady red light allows a right turn after a full stop, and also allows a left turn from a one-way street onto another one-way street after stopping. In both cases the driver must yield to pedestrians and to traffic lawfully using the intersection.
Question 3Colorado traffic laws and rules of the road
You are driving on a two-lane mountain road in Colorado and a solid yellow line is on your side of the centerline. What does this mean?
- The line marks a bicycle lane
- You must not cross the line to pass Correct answer.
- You may pass when the vehicle ahead is slow-moving
- Passing is allowed only at night
Explanation
A solid yellow line on your side of the centerline means passing is prohibited in your direction, typically because of limited sight distance or other hazards. On mountain roads this restriction protects drivers from head-on collisions around curves and crests.
Question 4Colorado traffic laws and rules of the road
In Colorado, when must you use your headlights?
- Only when it is raining
- Only between midnight and sunrise
- From sunset to sunrise, and whenever visibility is too poor to see people or vehicles clearly at 1,000 feet Correct answer.
- Only on unlit rural roads
Explanation
Colorado requires headlights from sunset to sunrise and any time conditions make people or vehicles not clearly visible at 1,000 feet. The visibility standard covers fog, heavy snow, and storms, not just darkness.
Question 5Colorado traffic laws and rules of the road
Under Colorado's graduated driver licensing program, a driver holding a learner's permit who is under 18 must be accompanied by:
- a parent or legal guardian only
- a certified driving instructor only
- a licensed driver who is at least 21 years old and has held a license for at least one year Correct answer.
- any licensed driver who is at least 18 years old
Explanation
Colorado requires a permit holder under 18 to drive with a licensed driver who is at least 21 and has held a valid license for at least one year. This supervision requirement applies whenever the permit holder is behind the wheel.
Question 6Colorado traffic laws and rules of the road
You are approaching a school bus that has stopped with its red lights flashing on a two-lane road without a median. What must you do?
- Slow down and pass carefully if children are not visible
- Stop only if you are traveling in the same direction as the bus
- Stop and remain stopped until the red lights stop flashing Correct answer.
- Sound your horn and continue at the posted speed
Explanation
On an undivided two-lane road, traffic in both directions must stop for a school bus displaying flashing red lights and wait until the lights stop flashing. This protects children who may be crossing the roadway.
Question 7Colorado traffic laws and rules of the road
When two vehicles arrive at an uncontrolled intersection at about the same time, Colorado law requires the driver on the left to yield to:
- the driver traveling straight
- the driver on the right Correct answer.
- the driver who signals first
- the driver with the larger vehicle
Explanation
At an uncontrolled intersection where vehicles arrive at approximately the same time, the driver on the left must yield the right-of-way to the vehicle on the right. If one vehicle arrived clearly first and has already entered the intersection, that vehicle goes first.
Question 8Colorado traffic laws and rules of the road
In Colorado, what happens to your driver license if you are convicted of driving while your ability is impaired by alcohol when you are under 21?
- Nothing happens unless your blood alcohol level exceeds the adult limit
- Your license is suspended, and the revocation or suspension is tied to the impaired-driving conviction Correct answer.
- You receive only a written warning
- You must retake the written test but keep driving privileges
Explanation
Colorado applies a zero-tolerance standard to drivers under 21, so an impaired-driving conviction results in license suspension or revocation. The underage standard is stricter than the adult limit, so even a low alcohol level can support the sanction.
Question 9Colorado traffic laws and rules of the road
A Colorado driver who is convicted of a first offense of driving while ability impaired by alcohol must generally:
- forfeit the vehicle permanently
- complete alcohol education or treatment and satisfy other court-ordered requirements Correct answer.
- serve jail time with no alternative
- install an ignition interlock on every vehicle owned by the family
Explanation
Colorado courts typically order alcohol education or treatment, fines, and other conditions for a first impaired-driving offense. Sentencing is set by the court, and completing the ordered program is part of satisfying the judgment.
Question 10Colorado traffic laws and rules of the road
What is the legal blood alcohol concentration limit for a driver who is 21 or older and operating a non-commercial vehicle in Colorado?
- 0.05 percent
- 0.08 percent Correct answer.
- 0.02 percent
- 0.10 percent
Explanation
Colorado uses 0.08 percent as the per se limit for adult drivers of non-commercial vehicles. A driver can still be convicted of impaired driving at a lower level if evidence shows the ability to drive was affected.
Question 11Colorado traffic laws and rules of the road
You are driving and an emergency vehicle approaches from behind with its siren and red lights on. What does Colorado law require?
- Stop in your lane immediately
- Pull over to the right edge of the roadway and stop until it passes Correct answer.
- Speed up to reach the next exit before it passes
- Continue at the same speed and lane position
Explanation
Drivers must yield to an approaching emergency vehicle using lights and siren by pulling to the right edge of the road and stopping until it passes. If you are in an intersection, clear it first and then pull over.
Question 12Colorado traffic laws and rules of the road
On a Colorado highway with three or more lanes in one direction, which lane should you normally use for passing?
- The far left lane Correct answer.
- The center lane
- Any lane, since lane choice is unrestricted
- The right lane
Explanation
On a multi-lane highway, the left lane is intended for passing and for faster-moving traffic, while the right lane is the normal travel lane. Colorado law also addresses left-lane use so that slower drivers do not block traffic.
Question 13Colorado traffic laws and rules of the road
What does a flashing yellow arrow signal mean for a left-turning driver?
- You may turn left after yielding to oncoming traffic and pedestrians Correct answer.
- You must stop and wait for a green arrow
- Left turns are prohibited
- You have an automatic protected right-of-way
Explanation
A flashing yellow arrow means the left turn is permitted but unprotected, so the driver must yield to oncoming traffic and pedestrians before turning. A steady green arrow, by contrast, gives a protected right-of-way.
Question 14Colorado traffic laws and rules of the road
In Colorado, what is the maximum speed limit in an alley?
- 10 mph
- 20 mph
- 25 mph
- 15 mph Correct answer.
Explanation
Colorado sets the maximum speed in an alley at 15 mph. Alleys have limited sight distance and frequent pedestrians or vehicles entering from driveways, so the low limit reduces risk.
Question 15Colorado traffic laws and rules of the road
A driver in Colorado must signal before turning or changing lanes continuously for at least:
- 50 feet
- 100 feet Correct answer.
- 25 feet
- 200 feet
Explanation
Colorado requires a turn or lane-change signal to be given continuously for at least 100 feet before the movement. Signaling earlier gives surrounding drivers time to react.
Question 16Colorado traffic laws and rules of the road
You are parking on a downhill slope next to a curb in Colorado. How should you turn your front wheels?
- Straight ahead
- It does not matter if the parking brake is set
- Toward the curb Correct answer.
- Away from the curb
Explanation
When parking downhill with a curb, turn the front wheels toward the curb so that if the vehicle rolls it will be stopped by the curb. On an uphill slope with a curb, the wheels are turned away from the curb.
Question 17Colorado traffic laws and rules of the road
In Colorado, a child who is under 8 years old must be restrained in a child restraint system when riding in a passenger vehicle, with limited exceptions such as:
- an adult is sitting next to the child
- the trip is shorter than five miles
- the child is riding in the back seat of any vehicle
- the child is at least 4 feet 9 inches tall Correct answer.
Explanation
Colorado's child restraint requirement applies to children under 8, but a child who is at least 4 feet 9 inches tall may use an adult safety belt instead. Proper fit matters because a seat belt that does not fit correctly can injure a small child.
Question 18Colorado traffic laws and rules of the road
You are driving on a wet Colorado road and your vehicle begins to hydroplane. What should you do?
- Accelerate to push through the water
- Ease off the accelerator and steer straight until traction returns Correct answer.
- Turn the wheel quickly from side to side
- Brake firmly and steer sharply
Explanation
In hydroplaning, the tires ride on a film of water and lose contact with the road, so easing off the accelerator and holding a steady course lets the tires regain grip. Hard braking or sharp steering during hydroplaning can cause a skid or loss of control.
Question 19Colorado traffic laws and rules of the road
On a Colorado road with no curb or sidewalk, how far from the edge of the roadway must you generally stop when parking?
- Within 24 inches
- Within 18 inches Correct answer.
- Within 6 inches
- Within 12 inches
Explanation
Where there is no curb or sidewalk, Colorado requires parking within 18 inches of the edge of the roadway. Where a curb exists, the standard is within 12 inches of the curb.
Question 20Colorado traffic laws and rules of the road
What is the meaning of a white painted curb in Colorado?
- Parking is allowed only long enough to load or unload passengers or mail Correct answer.
- Parking is allowed without time limit
- Parking is prohibited at all times
- Parking is reserved for disabled placard holders
Explanation
A white curb marks a zone where a driver may stop only briefly to pick up or drop off passengers or mail. It is not a place for extended parking.
Question 21Colorado traffic laws and rules of the road
In Colorado, when may you legally drive in a designated bicycle lane?
- Only during daylight hours
- When preparing to turn, and only after yielding to bicyclists Correct answer.
- Never, under any circumstance
- Whenever traffic is congested
Explanation
Drivers may enter a bicycle lane only when necessary to prepare for a turn, and they must yield to any bicyclists already using the lane. Using the lane as a passing or travel lane is not permitted.
Question 22Colorado traffic laws and rules of the road
Under Colorado's Move Over law, what must a driver do when approaching a stopped tow truck or maintenance vehicle with flashing lights on the roadside?
- Move over one lane if possible, or slow down if moving over is not safe Correct answer.
- Flash your high beams and continue
- Maintain speed and lane position
- Stop until the vehicle turns off its lights
Explanation
Colorado's Move Over law requires drivers to change lanes away from a stopped emergency, tow, or maintenance vehicle with flashing lights when it is safe to do so. If a lane change is not possible, the driver must slow down and proceed with caution.
Question 23Colorado traffic laws and rules of the road
You are driving on a two-lane road at night and a vehicle approaches with bright headlights. Where should you look to reduce glare?
- Toward the right edge of your lane Correct answer.
- At the centerline
- At your rearview mirror
- Directly at the oncoming headlights
Explanation
Looking toward the right edge of your lane keeps you oriented while avoiding the glare of oncoming headlights. Staring at the lights temporarily impairs night vision.
Question 24Colorado traffic laws and rules of the road
In Colorado, a driver may not follow a fire truck responding to an alarm closer than:
- 300 feet
- 100 feet
- One mile
- 500 feet Correct answer.
Explanation
Colorado prohibits following a fire truck responding to an alarm closer than 500 feet. The gap keeps the scene clear and gives the crew room to work.
Question 25Colorado traffic laws and rules of the road
What is the general rule for passing another vehicle on a two-lane Colorado road?
- Pass on the left across a solid yellow line if the vehicle ahead is slow
- Pass on the right whenever the vehicle ahead is turning left
- Pass whenever the road ahead appears clear for a short distance
- Pass on the left only when it is legal and safe, and return to your lane only after you can see the passed vehicle in your mirror Correct answer.
Explanation
Passing is permitted only when it is legal and safe, which means a broken line or permitted zone, adequate sight distance, and no oncoming traffic. A driver should return to the right lane only after the passed vehicle is visible in the mirror.
Question 26Colorado traffic laws and rules of the road
In Colorado, what must a driver do when a steady circular red traffic signal is displayed at an intersection and no turn is prohibited by signs?
- Stop completely, then turn right after yielding to traffic and pedestrians Correct answer.
- Stop only if other vehicles are present in the intersection
- Slow to 15 mph and proceed straight through the intersection
- Stop and remain stopped until the signal turns green in all cases
Explanation
Colorado follows the standard rule that a steady circular red light requires a full stop before the crosswalk or stop line. After stopping, a driver may turn right (or left onto a one-way street, unless posted otherwise) only after yielding the right-of-way to pedestrians and cross traffic. The turn is permissive, not mandatory, and the driver must still wait for a safe gap.
Question 27Colorado traffic laws and rules of the road
You are driving on a Colorado street and see a solid yellow center line on your side of the roadway. What does this line indicate?
- The lane is reserved for turning traffic only
- You may cross it to make a left turn into a driveway at any time
- Passing is permitted when the road ahead is clear
- Passing is prohibited on your side of the roadway Correct answer.
Explanation
A solid yellow line marks the left edge of travel for your direction and means you may not cross it to pass. You may still cross a solid yellow line to make a left turn into a driveway or side road when it is safe and legal. The restriction targets passing maneuvers, not all crossings.
Question 28Colorado traffic laws and rules of the road
In Colorado, when a pedestrian is crossing a roadway within a marked crosswalk at an intersection with no traffic signal, what is the driver's obligation?
- Stop only after the pedestrian reaches the center line
- Sound the horn and continue at the posted speed
- Yield the right-of-way and stop if necessary to let the pedestrian cross Correct answer.
- Proceed because pedestrians must wait for a gap in traffic
Explanation
Colorado law requires drivers to yield to pedestrians crossing within a crosswalk, and the driver must slow or stop as needed to avoid interfering with the crossing. The duty applies whether or not the pedestrian has already reached the middle of the road. Honking at a crossing pedestrian is not a substitute for yielding.
Question 29Colorado traffic laws and rules of the road
What does a diamond-shaped orange sign with black lettering on a Colorado highway generally indicate?
- A warning about a work zone or road condition ahead Correct answer.
- A hospital or emergency service location
- A mandatory lane designation for trucks
- A regulatory speed limit that applies at all times
Explanation
Orange diamond-shaped signs are used for construction and maintenance warnings, alerting drivers to workers, lane shifts, or temporary hazards ahead. Drivers should slow down and be prepared to change lanes or stop. Regulatory requirements such as speed limits appear on white rectangular signs.
Question 30Colorado traffic laws and rules of the road
A Colorado driver is approaching a railroad crossing with flashing red lights and no gate, and the lights are active. What should the driver do?
- Stop, look and listen, and proceed only when the lights stop flashing and the tracks are clear Correct answer.
- Slow to 15 mph and cross while watching for trains
- Continue across because the crossing has no gate
- Stop only if a train is visibly within 500 feet
Explanation
Active flashing red lights at a railroad crossing require a complete stop, regardless of whether a gate is present. The driver must remain stopped until the lights stop flashing and the tracks are confirmed clear, since a second train can follow closely. Proceeding on a guess about train distance is unsafe and unlawful.
Question 31Colorado traffic laws and rules of the road
On a Colorado mountain road, you are driving downhill and meet a large truck climbing uphill in the opposite direction. Which vehicle generally has the right-of-way on the narrow roadway?
- The downhill vehicle, because it can stop more easily
- Neither vehicle; both must back up to a wider point
- Whichever vehicle is traveling faster
- The uphill vehicle, because it may have difficulty restarting Correct answer.
Explanation
On steep grades, the vehicle traveling uphill generally has the right-of-way because stopping and restarting a heavy load on an incline is difficult and can be dangerous. The downhill driver should yield, pulling over or stopping where it is safe to let the uphill vehicle pass. This convention protects control of the climbing vehicle.
Question 32Colorado traffic laws and rules of the road
In Colorado, when may a driver legally make a U-turn on a roadway?
- Never, because U-turns are prohibited statewide
- Anywhere the roadway is wide enough to complete the turn
- Only where it can be done safely and is not prohibited by signs or law Correct answer.
- Only at intersections controlled by a green arrow
Explanation
Colorado allows U-turns where they are not prohibited by signs or law and can be completed safely without interfering with other traffic. Drivers must yield to oncoming and cross traffic while making the turn. Local ordinances and posted signs may further restrict where U-turns are allowed.
Question 33Colorado traffic laws and rules of the road
While driving on a Colorado interstate, you see a sign for a lane marked with a red X overhead. What does this mean for that lane?
- The lane is open to all traffic until the next exit
- The lane may be used only for passing
- The lane is closed ahead and you should move out of it Correct answer.
- The lane is reserved for high-occupancy vehicles
Explanation
A red X over a lane means the lane is closed to traffic, often because of a crash, maintenance, or a reversible-lane change. Drivers should merge into an open lane when it is safe to do so. A green arrow over a lane indicates that the lane is open.
Question 34Colorado traffic laws and rules of the road
In Colorado, what is required of a driver who is involved in a crash that causes injury to another person?
- Leave a note on the other vehicle and continue if the injury seems minor
- Stop, give aid, and report the crash to law enforcement without delay Correct answer.
- Report the crash only if the injured person requests it
- Continue to the nearest hospital and report the crash the next day
Explanation
Colorado law requires a driver involved in a crash resulting in injury to stop immediately, render reasonable assistance, and notify law enforcement. Failing to stop can lead to serious criminal charges. Leaving the scene, even briefly, violates the duty to remain and report.
Question 35Colorado traffic laws and rules of the road
On a Colorado road where the speed limit is 65 mph, what is the minimum following distance recommended under the three-second rule in good conditions?
- Three seconds behind the vehicle ahead Correct answer.
- Half a car length regardless of speed
- Ten car lengths at all speeds
- One second behind the vehicle ahead
Explanation
The three-second rule gives a driver time to perceive and react to a sudden stop by the vehicle ahead. At highway speeds the gap should be increased, and in rain, snow, or darkness it should be lengthened further. Counting seconds is more reliable than estimating car lengths.
Question 36Colorado traffic laws and rules of the road
You are driving in Colorado and your vehicle's brakes fail on a downhill grade. What is the safest first action?
- Pump the brakes firmly and downshift to a lower gear Correct answer.
- Turn off the ignition and steer toward the shoulder
- Shift to neutral and coast to the bottom of the hill
- Accelerate to build momentum for the uphill side
Explanation
Pumping the brakes can rebuild pressure in some systems, and downshifting uses engine braking to slow the vehicle. Turning off the ignition can lock the steering and is dangerous. Coasting in neutral removes engine braking and lets speed build on a downgrade.
Question 37Colorado traffic laws and rules of the road
In Colorado, when are you required to use your headlights while driving?
- Only on rural highways without streetlights
- Only when it is raining hard enough to use wipers
- From sunset to sunrise and whenever visibility is reduced by weather Correct answer.
- Only between midnight and 6 a.m.
Explanation
Colorado requires headlights from sunset to sunrise and whenever conditions such as fog, rain, or snow make it hard to see or be seen. Headlights improve the visibility of your vehicle to others as well as your own view. Using them only at night or only in heavy rain misses many required situations.
Question 38Colorado traffic laws and rules of the road
You are driving on a Colorado road and a bicyclist is riding in the same direction ahead of you in a narrow lane. What is the safest and legally required approach?
- Speed up and pass within the same lane without changing position
- Honk repeatedly until the cyclist moves onto the shoulder
- Pass closely to discourage the cyclist from holding up traffic
- Wait until you can pass with a safe distance and do not crowd the cyclist Correct answer.
Explanation
Colorado law requires drivers to give bicyclists a safe passing distance and to pass only when it can be done without endangering them. Crowding or honking at a cyclist can cause a crash and is not a lawful way to clear the lane. The driver should slow and wait for a safe opportunity to pass.
Question 39Colorado traffic laws and rules of the road
A Colorado driver is stopped at a red light and wants to turn left from a two-way street onto another two-way street. When is a left turn on red permitted?
- Never, because left turns on red are prohibited in Colorado
- Whenever no oncoming traffic is visible
- Only when a police officer directs the turn
- Only if the driver first stops and the turn is from a one-way street onto another one-way street, unless posted otherwise Correct answer.
Explanation
Colorado permits a left turn on red only when turning from a one-way street onto another one-way street, after a complete stop and yielding, and only where no sign prohibits it. A left turn from a two-way street onto a two-way street on red is not allowed. The driver must still yield to pedestrians and cross traffic.
Question 40Colorado traffic laws and rules of the road
On a Colorado roadway, you are approaching a hillcrest where you cannot see oncoming traffic. What does the law require regarding passing?
- Passing is allowed on the shoulder to maintain speed
- Passing is allowed if the vehicle ahead is moving slowly
- Passing is permitted if you flash your headlights first
- Passing is prohibited when you cannot see far enough ahead to complete it safely Correct answer.
Explanation
Passing is prohibited where visibility is limited, such as at a hillcrest or curve, because the driver cannot see far enough to complete the maneuver safely. Flashing headlights does not create a right to pass. Passing on the shoulder is generally unlawful and especially dangerous near a blind crest.
Question 41Traffic signs, signals, and pavement markings
A steady red traffic light means you must come to a complete stop. What are you allowed to do next?
- Stop only if a vehicle is approaching from the cross street
- Stop, then proceed when the way is clear as if it were a stop sign
- Slow down and continue through if no traffic is coming
- Remain stopped until the light turns green, unless a turn is permitted after stopping Correct answer.
Explanation
A steady red signal requires a full stop before the intersection or limit line, and you stay stopped until green. The one exception is a right turn (or left turn from a one-way street onto a one-way street) where local rules and signs permit turning after yielding.
Question 42Traffic signs, signals, and pavement markings
You approach an intersection where a traffic signal is dark because of a power failure. What should you do?
- Stop, then treat the intersection as an all-way stop if signals are out in all directions Correct answer.
- Proceed through without stopping since the signal is not operating
- Wait at the intersection until a police officer arrives to direct traffic
- Sound your horn and proceed slowly through the intersection
Explanation
When a signal is dark, the intersection becomes uncontrolled and the all-way stop rules apply if the signals are out for every direction. You must stop and yield according to arrival order before proceeding.
Question 43Traffic signs, signals, and pavement markings
A flashing yellow light at an intersection tells you to:
- Stop only when pedestrians are present
- Yield to traffic already inside the intersection and then stop
- Come to a complete stop before entering
- Slow down and proceed with caution Correct answer.
Explanation
A flashing yellow signal is a warning to slow down and cross carefully. It does not require a stop, but you must still yield to vehicles and pedestrians already lawfully in the intersection.
Question 44Traffic signs, signals, and pavement markings
At an intersection with a flashing red light in your direction, you must:
- Stop only if a stop line is painted on the pavement
- Slow down and continue if the intersection looks clear
- Wait for the light to turn green before entering
- Stop completely, then proceed when it is safe, like a stop sign Correct answer.
Explanation
A flashing red signal carries the same requirement as a stop sign: a full stop, then yield to cross traffic and pedestrians before proceeding. It stays flashing, so no green phase will come.
Question 45Traffic signs, signals, and pavement markings
A green arrow pointing left appears in your signal head while the circular light is red. What does this mean?
- You may proceed straight or turn left
- You must wait for the circular light to turn green
- You may turn left only after yielding to oncoming traffic
- You have a protected left turn and oncoming traffic is stopped Correct answer.
Explanation
A green arrow gives a protected movement in the direction of the arrow, meaning conflicting traffic faces a red signal. You may turn left without yielding to oncoming vehicles, though you still yield to pedestrians in the crosswalk.
Question 46Traffic signs, signals, and pavement markings
A steady circular green light allows you to:
- Proceed only straight ahead
- Proceed straight or turn, yielding to pedestrians and oncoming traffic when turning Correct answer.
- Enter the intersection only if you can clear it before the light changes
- Turn left without yielding because the light is green
Explanation
A circular green permits all movements that are otherwise legal, but a left turn across oncoming traffic is unprotected and you must yield. Pedestrians in the crosswalk also have the right of way.
Question 47Traffic signs, signals, and pavement markings
A pedestrian is in the crosswalk on your side of the road while your light is green. What must you do?
- Stop and wait for the pedestrian to clear your path Correct answer.
- Drive around the pedestrian within your lane
- Proceed because the green light gives you the right of way
- Sound your horn so the pedestrian hurries across
Explanation
Pedestrians lawfully in a crosswalk have the right of way even when drivers have a green light. You must stop and let them clear your path before proceeding.
Question 48Traffic signs, signals, and pavement markings
A solid white line painted across your lane just before an intersection is a:
- Lane-drop marking
- Crosswalk warning line
- Yield line
- Stop line Correct answer.
Explanation
A solid white stop line shows exactly where you must stop for a signal, stop sign, or crosswalk. You stop before the line so pedestrians and cross traffic have clear space.
Question 49Traffic signs, signals, and pavement markings
Double solid yellow lines in the center of a road mean:
- Passing is prohibited in both directions, though left turns across them may be allowed Correct answer.
- Passing is allowed when the road ahead is clear
- You may cross them to pass a slow-moving vehicle
- The lane to the left is reserved for buses
Explanation
Double solid yellow center lines separate traffic moving in opposite directions and prohibit passing for traffic on both sides. Left turns into or out of driveways and side roads may still be permitted where not otherwise restricted.
Question 50Traffic signs, signals, and pavement markings
A broken yellow line beside your lane with a solid yellow line on the other side means:
- You may pass when it is safe; oncoming traffic may not Correct answer.
- Passing is allowed in both directions
- Neither direction may pass
- Only oncoming traffic may pass
Explanation
When a broken and a solid yellow line run together, the rule follows the line nearest your lane. A broken line on your side permits passing when safe; the solid line on the other side forbids it for oncoming traffic.
