Question 1Traffic Signs, Signals, and Road Markings

A police officer standing in the middle of an intersection faces you and raises one hand with the palm toward you. What must you do?

  1. Sound your horn and proceed with caution
  2. Turn right only after checking for traffic
  3. Continue through the intersection without slowing
  4. Stop and remain stopped until the signal changes Correct answer.

Explanation

A raised hand with the palm facing your direction is a stop signal that carries the same force as a red light. You must halt before the intersection or crosswalk and stay stopped until the officer releases you. Officer directions override signs, signals, and markings.

Question 2Traffic Signs, Signals, and Road Markings

You approach a steady circular red light at an intersection and intend to turn right. Assuming no sign forbids it, what is the correct procedure?

  1. Stop only if a vehicle is directly behind you
  2. Slow down and turn without stopping if no vehicle is close
  3. Wait for a green arrow before moving at all
  4. Stop fully, yield to pedestrians and cross traffic, then turn when clear Correct answer.

Explanation

A steady red light requires a complete stop before the crosswalk or stop line. After stopping, a right turn is permitted unless a sign prohibits it, but you must yield to pedestrians in the crosswalk and to vehicles lawfully in the intersection. A rolling slowdown does not satisfy the stop requirement.

Question 3Traffic Signs, Signals, and Road Markings

What does a flashing circular yellow light at an intersection mean?

  1. Only pedestrians may proceed
  2. Proceed with caution after yielding as needed Correct answer.
  3. The signal is broken and normal rules are suspended
  4. Come to a complete stop before entering

Explanation

A flashing yellow signal warns that you may proceed only with caution. You should slow down, scan for pedestrians and crossing traffic, and yield where required. It does not require a full stop unless other rules, such as a stop sign or yield obligation, apply.

Question 4Traffic Signs, Signals, and Road Markings

A flashing circular red light at an intersection functions in the same way as which of the following?

  1. A green arrow
  2. A stop sign Correct answer.
  3. A speed limit sign
  4. A yield sign

Explanation

A flashing red light requires you to come to a complete stop, then proceed only when it is safe, exactly as at a stop sign. Right-of-way rules still apply after you stop. It is not a mere caution signal.

Question 5Traffic Signs, Signals, and Road Markings

A solid yellow center line on your side of the roadway indicates what?

  1. Passing is permitted whenever the road is clear
  2. You may park along that edge of the road
  3. Passing is prohibited for traffic in your direction Correct answer.
  4. The road is one-way in your direction

Explanation

A solid yellow line on your side of the center line means you may not cross it to pass. Yellow lines separate traffic moving in opposite directions, and the solid line restricts the side it borders. A broken yellow line on your side would allow passing when safe.

Question 6Traffic Signs, Signals, and Road Markings

A broken white line separating two lanes traveling in the same direction means what?

  1. You may change lanes when it is safe to do so Correct answer.
  2. Lane changes are prohibited at all times
  3. Traffic in the left lane must turn left
  4. The lane to the right is for parking only

Explanation

White lines separate traffic moving in the same direction, and a broken white line permits lane changes when safe. You must still signal and check mirrors and blind spots. A solid white line signals that lane changes are discouraged or prohibited.

Question 7Traffic Signs, Signals, and Road Markings

What is the meaning of a red octagonal sign?

  1. Come to a complete stop Correct answer.
  2. Reduce speed ahead
  3. No entry for any vehicle
  4. Yield to traffic on the right

Explanation

The eight-sided red sign is the stop sign, and its unique shape lets drivers recognize it even when covered by snow or viewed from behind. You must stop completely at the stop line, crosswalk, or edge of the intersection. Yielding alone does not satisfy it.

Question 8Traffic Signs, Signals, and Road Markings

A yellow diamond-shaped sign is generally used to convey which type of information?

  1. A service such as fuel or lodging
  2. A legal requirement you must obey at that spot
  3. A route number for a highway
  4. A warning about a road condition or hazard ahead Correct answer.

Explanation

Yellow diamond signs are warning signs that alert you to hazards or changes ahead, such as curves, intersections, or pedestrian crossings. They tell you to adjust speed and attention rather than imposing a specific legal command. Regulatory signs, by contrast, are usually white rectangles or red circles.

Question 9Traffic Signs, Signals, and Road Markings

You are driving and a school bus ahead of you stops with its red lights flashing on an undivided two-lane road. What must you do?

  1. Sound your horn to warn children and continue
  2. Stop and wait until the red lights stop flashing before proceeding Correct answer.
  3. Pass only if children are not visible
  4. Slow down and pass carefully on the left

Explanation

On an undivided roadway, traffic in both directions must stop for a school bus displaying flashing red lights. You may proceed only after the lights stop flashing and the bus begins to move. Passing a stopped school bus with its red lights on is a serious violation.

Question 10Traffic Signs, Signals, and Road Markings

On a divided highway with a physical median, a school bus on the opposite side stops with red lights flashing. What does the law require of you?

  1. Stop immediately in your lane until the lights go off
  2. Reduce speed to 20 km/h and pass the bus
  3. Continue without stopping, because the opposing roadway is separated by a median Correct answer.
  4. Stop only if the median is narrower than three meters

Explanation

The stop requirement for school buses applies to traffic approaching from either direction on an undivided road. When a physical median or barrier separates the opposing directions, drivers on the opposite side are not required to stop. Drivers traveling behind the bus on its own roadway must still stop.

Question 11Traffic Signs, Signals, and Road Markings

A sign shows a black arrow curving to the left inside a yellow diamond. What should you do?

  1. Move into the left lane to pass
  2. Expect the road to end and merge left
  3. Slow down and prepare for a curve to the left Correct answer.
  4. Make a mandatory left turn at the next intersection

Explanation

A yellow diamond with a curving arrow is a warning sign for a curve ahead in the direction shown. You should reduce speed before entering the curve and keep to your lane. A mandatory turn is indicated by a regulatory sign, not this warning diamond.

Question 12Traffic Signs, Signals, and Road Markings

What does a white rectangular sign with the word YIELD and a red triangle symbol require?

  1. Come to a complete stop in every case
  2. Merge without adjusting speed
  3. Slow down and give the right-of-way to traffic on the intersecting road Correct answer.
  4. Stop only when a vehicle is already in the intersection

Explanation

At a yield sign you must slow down and give way to vehicles and pedestrians already on the intersecting road or crosswalk. A full stop is required only when necessary to avoid conflict. If the way is clearly safe, you may proceed without stopping.

Question 13Traffic Signs, Signals, and Road Markings

You see a sign with a red circle and a white horizontal bar. What does it mean?

  1. No parking
  2. Do not enter Correct answer.
  3. Stop required
  4. One-way traffic

Explanation

The red circle with a white horizontal bar is the do-not-enter sign, placed where traffic may not proceed, such as the exit of a one-way street. Entering past it puts you against the flow of traffic. It is distinct from the stop sign, which requires a halt but permits later movement.

Question 14Traffic Signs, Signals, and Road Markings

A road has a solid white line on the right edge and a broken white line on the left of your lane. Which statement is correct?

  1. The right edge line marks the roadway boundary, and the broken line allows lane changes to the left Correct answer.
  2. The broken line means oncoming traffic shares your lane
  3. The right edge line permits parking anywhere beyond it
  4. Both lines forbid any lane change

Explanation

A solid white edge line marks the right boundary of the travel lane, while a broken white line between same-direction lanes permits lane changes when safe. White lines never separate opposing traffic. Crossing the edge line is generally limited to emergencies or designated shoulders.

Question 15Traffic Signs, Signals, and Road Markings

What do double solid yellow center lines indicate?

  1. Passing is prohibited for traffic in both directions Correct answer.
  2. Passing is allowed for traffic in both directions
  3. The road carries one-way traffic
  4. A center turn lane is available to both directions

Explanation

Two solid yellow lines mean neither direction may cross them to pass. They are used where sight distance or roadway conditions make passing unsafe. A broken yellow line on one side would allow that side to pass when clear.

Question 16Traffic Signs, Signals, and Road Markings

You are in a lane marked with a white left-turn arrow painted on the pavement, and the traffic light is a green arrow pointing left. What does this combination allow?

  1. No movement until the light turns green without an arrow
  2. A left turn only after yielding to oncoming traffic
  3. A protected left turn while opposing traffic is stopped Correct answer.
  4. A U-turn only

Explanation

A green arrow gives a protected movement, meaning opposing traffic is held by a red light while you turn. The pavement arrow confirms the lane's designated movement. You may still need to watch for pedestrians, but you need not yield to oncoming vehicles.

Question 17Traffic Signs, Signals, and Road Markings

A steady circular green light is showing and you want to turn left across oncoming traffic. What is required?

  1. Wait for a green arrow in all cases
  2. Proceed immediately because green means you have the right-of-way
  3. Yield to oncoming vehicles and pedestrians before completing the turn Correct answer.
  4. Turn only from the rightmost lane

Explanation

A circular green light permits movement but does not grant an absolute right-of-way. When turning left across traffic, you must yield to oncoming vehicles close enough to pose a hazard and to pedestrians in the crosswalk. A green arrow, by contrast, would provide protection.

Question 18Traffic Signs, Signals, and Road Markings

What does a yellow diamond sign showing a pedestrian figure inside a crosswalk symbol warn you to expect?

  1. A sidewalk that ends ahead
  2. A school zone with a reduced speed limit
  3. A hospital entrance
  4. A pedestrian crossing ahead where people may enter the roadway Correct answer.

Explanation

The pedestrian crossing warning sign alerts drivers to a marked crossing ahead so they can slow down and scan for people entering the road. It does not itself set a speed limit. School zones use separate signs, often with a reduced speed plaque.

Question 19Traffic Signs, Signals, and Road Markings

A center lane bounded by two solid yellow lines with broken yellow segments inside is used for what purpose?

  1. Two-way left turns by traffic from either direction Correct answer.
  2. Emergency stopping only
  3. Bus travel only
  4. Passing slower vehicles in both directions

Explanation

The two-way left-turn lane lets drivers from either direction move into the center to wait for a safe gap before turning left. It is not a passing lane, and drivers should enter it only shortly before turning. Through travel in this lane is prohibited.

Question 20Traffic Signs, Signals, and Road Markings

You approach an intersection where the traffic signal is dark because of a power failure. How should you treat the intersection?

  1. As a yield-only intersection for the busier road
  2. As closed until a police officer arrives
  3. As an all-way stop, stopping and yielding according to arrival order Correct answer.
  4. As an uncontrolled intersection where you may proceed at speed

Explanation

When a signal is completely dark, drivers should treat the intersection as an all-way stop. Each vehicle stops, then proceeds in order of arrival, with right-of-way yielded as at any four-way stop. Proceeding without stopping invites collisions.

Question 21Traffic Signs, Signals, and Road Markings

A sign displays a black symbol of a car on a slippery, curving road inside a yellow diamond. What action is most appropriate?

  1. Maintain speed to carry momentum through the curve
  2. Apply the brakes firmly while in the curve
  3. Accelerate to shorten time on the slippery surface
  4. Reduce speed before the hazard and avoid sudden braking or steering Correct answer.

Explanation

Slippery-when-wet warning signs tell you that traction may be reduced, so you should slow down before reaching the hazard. Sudden braking or sharp steering can cause a skid on a low-friction surface. Smooth, gradual inputs are the safest response.

Question 22Traffic Signs, Signals, and Road Markings

A solid yellow line is on your side of the center line, but a broken yellow line is on the opposite side. What does this configuration permit?

  1. Only you may pass when safe
  2. Traffic coming toward you may pass when safe, but you may not Correct answer.
  3. Neither direction may pass
  4. Both directions may pass when safe

Explanation

When one side of the center line is solid and the other broken, only the traffic beside the broken line may cross to pass. The solid line on your side forbids you from passing. This pattern is common where sight distance differs between the two directions.

Question 23Traffic Signs, Signals, and Road Markings

What is the correct response to a steady red arrow pointing left?

  1. Turn left only if no pedestrians are present
  2. Treat it as a flashing yellow and proceed cautiously
  3. Stop and do not turn left until the arrow changes Correct answer.
  4. Turn left after yielding to oncoming traffic

Explanation

A red arrow is a directional stop signal that prohibits the indicated movement for as long as it is displayed. You must stop and wait; unlike a circular red, a red arrow generally does not permit a turn on red. The movement becomes lawful when a green arrow or other permissive signal appears.

Question 24Traffic Signs, Signals, and Road Markings

A flashing yellow arrow pointing left appears at an intersection. What does it allow?

  1. No turn until a green arrow appears
  2. A protected left turn with no need to yield
  3. A left turn after yielding to oncoming traffic and pedestrians Correct answer.
  4. A U-turn only

Explanation

A flashing yellow arrow means you may turn in the direction shown, but you must first yield to oncoming traffic and pedestrians because the movement is not protected. It is more permissive than a red arrow and less protective than a green arrow. Yielding is the key distinction.

Question 25Traffic Signs, Signals, and Road Markings

You are driving at night on an unlit road and approach a sign whose shape you can barely see but which appears to be a downward-pointing triangle with a red border. What does this shape indicate?

  1. A construction zone ahead
  2. A stop requirement at the intersection ahead
  3. A yield requirement at the intersection ahead Correct answer.
  4. A railway crossing ahead

Explanation

The inverted triangle with a red border is the yield sign, and its distinctive shape is designed for recognition even in poor visibility. Drivers must slow and give way to traffic on the intersecting road. The stop sign is the only octagon, and its shape is equally distinctive.

Question 26Traffic Signs, Signals, and Road Markings

A circular sign with a red border and a black diagonal slash through a symbol carries which meaning?

  1. The hazard shown exists only during rain
  2. The maneuver shown is recommended for safety
  3. The rule shown applies only to commercial trucks
  4. The maneuver or vehicle shown is prohibited Correct answer.

Explanation

A red circle with a diagonal slash is the international prohibition symbol, so the activity or vehicle pictured is forbidden. The slash converts the sign into a restriction rather than advice. Drivers must not perform the depicted action at that location.

Question 27Traffic Signs, Signals, and Road Markings

What does a black crossbuck sign with the words RAILROAD CROSSING tell you?

  1. You must stop completely before the tracks every time
  2. You are at a passive crossing where you must yield to trains Correct answer.
  3. A train crew will flag you across the tracks
  4. The crossing is permanently closed to vehicles

Explanation

The crossbuck marks a passive railroad crossing without gates or lights, and it places a duty on the driver to look, listen and yield to any approaching train. A full stop is required only when a train is coming or a stop line and STOP plate are present. Never assume the way is clear just because no signal is active.

Question 28Traffic Signs, Signals, and Road Markings

A blue rectangular sign showing a white symbol of a bed indicates what?

  1. A rest area or lodging facility ahead Correct answer.
  2. A mandatory overnight parking ban
  3. A hospital emergency entrance
  4. A weigh station for heavy vehicles

Explanation

Blue rectangular signs provide traveler services, and the bed symbol identifies lodging or a rest area where drivers can stop. These signs are informational, not regulatory. They do not impose any obligation on the driver.

Question 29Traffic Signs, Signals, and Road Markings

A steady circular red light is showing and you intend to turn right at the intersection. What is the correct procedure?

  1. Sound the horn and proceed through the red light
  2. Stop fully, yield to pedestrians and traffic, then turn when clear unless a sign forbids it Correct answer.
  3. Wait for the light to turn green in every case
  4. Turn immediately because right turns are always permitted on red

Explanation

A right turn on red is permitted only after a complete stop and only after yielding to pedestrians and cross traffic, and only where no sign prohibits the turn. The stop must come before the crosswalk or stop line. Turning without stopping is a violation even when the way looks clear.

Question 30Traffic Signs, Signals, and Road Markings

What does a flashing red light at an intersection require of a driver?

  1. Stop, then proceed when it is safe, as at a stop sign Correct answer.
  2. Treat the intersection as uncontrolled with no rules
  3. Yield only to vehicles coming from the right
  4. Slow down and proceed without stopping

Explanation

A flashing red signal operates exactly like a stop sign: come to a complete stop, yield to traffic and pedestrians with the right of way, then proceed when safe. It is not a caution-only signal. Failing to stop at a flashing red is a moving violation.

Question 31Traffic Signs, Signals, and Road Markings

A steady green arrow pointing straight ahead is displayed together with a circular red light. What may you do?

  1. Wait for the circular light to turn green before moving
  2. Turn left because the arrow overrides the red light for all movements
  3. Proceed in any direction you choose
  4. Proceed straight in the direction of the arrow after yielding to pedestrians and traffic already in the intersection Correct answer.

Explanation

A green arrow authorizes only the movement it shows, even while other movements remain stopped by the red light. Drivers proceeding on the arrow must still yield to pedestrians and to traffic legally within the intersection. The arrow does not authorize turns it does not depict.

Question 32Traffic Signs, Signals, and Road Markings

What do raised pavement markers or painted diagonal stripes inside a painted island indicate?

  1. An area that vehicles should not enter or drive across Correct answer.
  2. A lane reserved for overtaking
  3. A legal parking area for short stops
  4. A pedestrian refuge where cars may wait

Explanation

Diagonal stripes and chevron markings, often called ghost islands, separate or channel traffic and mark areas that vehicles must not enter. They are painted where driving is unsafe or where lanes diverge. Crossing them can put a vehicle in conflict with opposing or merging traffic.

Question 33Traffic Signs, Signals, and Road Markings

A white rectangular sign with black lettering reading ONE WAY and an arrow shows what?

  1. Only buses may use the road
  2. Traffic on that road moves only in the direction of the arrow Correct answer.
  3. The road has one lane for each direction
  4. The road is closed to through traffic

Explanation

The ONE WAY sign informs drivers that all traffic on that roadway travels in the direction indicated by the arrow. Entering against the arrow is a serious violation that can cause a head-on collision. The sign is informational and does not restrict who may use the road.

Question 34Traffic Signs, Signals, and Road Markings

You are approaching an intersection and the signal changes from green to steady yellow as you near the stop line. What is the correct action?

  1. Stop if you can do so safely, otherwise proceed through with caution Correct answer.
  2. Reverse to the stop line if you have already crossed it
  3. Accelerate to clear the intersection before the red appears
  4. Stop abruptly in the intersection if you cannot halt before the line

Explanation

A steady yellow light warns that the red is about to appear and means stop if a safe stop is possible. If stopping would require harsh braking that risks a rear-end collision, continue through and clear the intersection. Reversing or stopping inside the intersection creates new hazards.

Question 35Traffic Signs, Signals, and Road Markings

What does a pennant-shaped yellow sign with black lettering signify?

  1. A school zone speed limit applies
  2. A pedestrian crossing is located ahead
  3. A construction zone begins ahead
  4. A no-passing zone begins here Correct answer.

Explanation

The pennant shape is reserved in many jurisdictions for the NO PASSING ZONE warning, which marks the start of a stretch where overtaking is unsafe. The sign reinforces the solid yellow center line that accompanies it. Passing where this sign is posted is prohibited.

Question 36Traffic Signs, Signals, and Road Markings

A yellow diamond sign shows a black symbol of a truck on a steep downgrade with the word USE LOW GEAR. What does this advise?

  1. Drivers should select a lower gear to control speed on the descent Correct answer.
  2. Trucks must exit the road at the next junction
  3. All vehicles must stop to check their brakes
  4. The grade is too steep for any vehicle to descend

Explanation

The sign warns of a long or steep descent where engine braking in a low gear helps control speed and prevents brake fade. Relying on the footbrake continuously can overheat and fail. The sign is advisory for all drivers, not only trucks.

Question 37Traffic Signs, Signals, and Road Markings

A sign shows a black bicycle inside a yellow diamond. What hazard does it warn of?

  1. Cyclists crossing or sharing the roadway ahead Correct answer.
  2. A bicycle repair shop ahead
  3. A path where bicycles are prohibited
  4. A lane reserved exclusively for bicycles

Explanation

A yellow diamond is a warning sign, so the bicycle symbol alerts drivers that cyclists may be crossing or sharing the road ahead. Drivers should reduce speed and scan for cyclists who may be hard to see. Prohibition or reservation of a lane would be shown by regulatory signs, not this warning.

Question 38Traffic Signs, Signals, and Road Markings

You see a solid white line along the left edge of your lane with a broken white line on the right, on a multi-lane road moving in one direction. What does the solid line generally indicate?

  1. The lane to the left is reserved for oncoming traffic
  2. Lane changes across it are discouraged or prohibited Correct answer.
  3. You must increase speed immediately
  4. Parking is permitted along that line

Explanation

On a one-way roadway, a solid white line marks a lane boundary that should not be crossed, such as the edge of an exit lane or a lane where weaving is unsafe. Broken white lines, by contrast, permit lane changes when safe. Drivers should follow the restriction rather than treat it as decoration.

Question 39Traffic Signs, Signals, and Road Markings

What is the meaning of a yellow X or diagonal arrows displayed above a reversible lane?

  1. The lane is closed or must be vacated for oncoming traffic Correct answer.
  2. The lane is a dedicated turning lane
  3. The lane is open for travel in your direction
  4. The lane is reserved for high-occupancy vehicles

Explanation

Lane-control signals over reversible lanes use a yellow X or downward diagonal arrows to warn that the lane is about to change direction or is closed to your movement. Drivers must leave the lane safely before the direction reverses. A green downward arrow indicates the lane is open for travel.

Question 40Traffic Signs, Signals, and Road Markings

A white rectangular sign with a red circle and the number 50 inside it, placed at the roadside, means what?

  1. Fuel is available in 50 kilometres
  2. The road has 50 metres of clear sight distance
  3. The minimum safe following distance is 50 metres
  4. The maximum permitted speed is 50 kilometres per hour Correct answer.

Explanation

A red circle around a numeral is a regulatory speed limit sign, setting the maximum legal speed for that stretch of road. The limit applies until another sign changes it. Exceeding it is an offence regardless of traffic conditions.

Question 41Traffic Signs, Signals, and Road Markings

You are driving at night and see a sign whose shape is a downward-pointing triangle with a red border. What does it require?

  1. Yield the right of way to traffic on the intersecting road Correct answer.
  2. Turn back because the road is closed
  3. Proceed at full speed because the road ahead has priority
  4. Come to a complete stop before proceeding

Explanation

The inverted triangle with a red border is the yield sign, requiring the driver to slow down and give way to traffic already on the intersecting road. A complete stop is needed only if traffic makes it necessary. The sign does not grant priority.

Question 42Traffic Signs, Signals, and Road Markings

A yellow diamond sign shows a black symbol of two arrows merging into one lane. What should the driver anticipate?

  1. A lane will end and traffic must merge into the remaining lane Correct answer.
  2. The road will divide into two separate carriageways
  3. A sharp right turn is coming immediately
  4. The road surface will change to gravel

Explanation

The merge warning tells drivers that a lane is ending and that vehicles must blend into the continuing lane. Drivers should adjust speed and position early to merge smoothly. Forcing a merge at the last moment causes sideswipes and sudden braking.

Question 43Traffic Signs, Signals, and Road Markings

What does a solid yellow line on your side of a two-way road, combined with a broken yellow line on the opposite side, permit you to do?

  1. Never pass, because a solid yellow line faces you Correct answer.
  2. Drive on the left side continuously as in a one-way street
  3. Pass when the way ahead is clear, because the broken line faces oncoming traffic
  4. Pass only if you exceed the posted speed limit

Explanation

A solid yellow line on your side forbids you from crossing it to pass, while the broken line on the other side allows oncoming traffic to pass when safe. The line nearest your vehicle governs your movement. Passing remains prohibited until the solid line ends.

Question 44Traffic Signs, Signals, and Road Markings

A sign shows a black arrow bending sharply to the right with the words 40 km/h beneath it inside a yellow diamond. What does the plate mean?

  1. The speed limit is 40 km/h at all times on this road
  2. The curve is 40 metres ahead
  3. A safe advisory speed of 40 km/h is recommended for the curve Correct answer.
  4. Only vehicles over 40 km/h may use the curve

Explanation

An advisory speed plate on a curve warning sign recommends the speed at which the curve can be negotiated comfortably under good conditions. It is guidance, not a legal maximum, though exceeding it in poor weather is unsafe. The actual regulatory limit is posted separately.

Question 45Traffic Signs, Signals, and Road Markings

You approach a junction where a traffic officer is directing vehicles with hand signals that conflict with the green light. Whose instruction do you follow?

  1. The traffic signal, because it is the permanent control
  2. The vehicle ahead of you, by following its path
  3. The officer, because an authorized officer overrides signals and signs Correct answer.
  4. Whichever instruction allows you to move first

Explanation

An authorized traffic officer directing traffic takes precedence over signals, signs and markings. Drivers must obey the officer's signals even when a light shows green. Following the light against an officer's direction is a violation and creates conflict in the junction.

Question 46Traffic Signs, Signals, and Road Markings

A yellow diamond sign shows a black symbol of a traffic signal with the word SIGNAL AHEAD. What should you do?

  1. Be prepared to stop if the signal changes as you approach Correct answer.
  2. Maintain speed because the signal will be green
  3. Sound the horn to warn other drivers
  4. Change lanes immediately to the right

Explanation

The SIGNAL AHEAD warning tells drivers that a signalized intersection is approaching, possibly hidden by a crest or curve, so they should be ready to stop. Speed should be adjusted so a safe stop is possible if the light turns yellow. The sign does not indicate the current signal phase.

Question 47Traffic Signs, Signals, and Road Markings

A bus lane is marked on the pavement with the word BUS and a solid white boundary line. What does this mean for an ordinary private car during the posted hours?

  1. The car must drive in the lane to keep the traffic lane clear
  2. The car may use the lane freely to overtake congestion
  3. The car must keep out of the lane except where signs permit entry Correct answer.
  4. The car may use the lane only when raining

Explanation

A bus lane marked with the word BUS and bounded by a solid line is reserved for buses during the posted times, and other vehicles must stay out except where signs allow brief entry for turning. Entering to bypass congestion is an offence. The restriction is enforced by signs and markings together.

Question 48Traffic Signs, Signals, and Road Markings

A sign shows a red circle with a white arrow turning left and a red diagonal slash across it. What does it prohibit?

  1. Left turns at that intersection Correct answer.
  2. Through traffic continuing straight
  3. All turns in both directions
  4. U-turns only

Explanation

The red circle with a slash over a left-turn arrow is a regulatory prohibition of left turns at that location. Drivers must choose another route or turn later where permitted. The slash is what converts the arrow sign into a prohibition.

Question 49Traffic Signs, Signals, and Road Markings

On a road with three lanes in your direction, you see a broken white line between your lane and the lane to your right, but a double solid white line between your lane and the lane to your left. What does the double solid line indicate?

  1. Crossing between the two lanes is prohibited, even to overtake Correct answer.
  2. The left lane ends immediately
  3. The left lane is reserved for slow vehicles
  4. Traffic in the left lane travels in the opposite direction

Explanation

Double solid white lines between lanes moving in the same direction prohibit crossing from one lane to the other, often to protect a high-occupancy or exit lane. Drivers must stay in their lane until the restriction ends. A broken line elsewhere does not override the double solid restriction.

Question 50Traffic Signs, Signals, and Road Markings

You are in a lane controlled by a green downward arrow, but the lane beside you shows a red X. What is the correct understanding of the two signals?

  1. Your lane is open to travel and the adjacent lane is closed to traffic Correct answer.
  2. The red X means the adjacent lane is for oncoming traffic only
  3. Both lanes are open because the signals differ only in colour
  4. Both lanes are closed until a police officer arrives

Explanation

Overhead lane-control signals apply individually to each lane: a green arrow opens that lane and a red X closes it. Drivers must not enter a lane marked with a red X because workers, oncoming traffic or a hazard may occupy it. The signals must be read lane by lane, not as a single instruction.
