Question 1Road Signs and Signals

In Ontario, a stop sign is an octagon. What are its colours?

  1. Green with white letters
  2. White with red letters
  3. Red with white letters Correct answer.
  4. Yellow with black letters

Explanation

Ontario stop signs are red octagons with white lettering. The unique eight-sided shape lets drivers identify the sign from behind and in poor weather, and it always requires a full stop at the stop line, crosswalk or edge of the intersection.

Question 2Road Signs and Signals

At an intersection controlled by a yield sign, you must:

  1. Sound your horn before proceeding
  2. Accelerate to merge ahead of traffic
  3. Slow down and yield to cross traffic Correct answer.
  4. Come to a full stop before entering

Explanation

A yield sign requires you to slow down and give the right-of-way to vehicles already on the intersecting road, and to pedestrians. You only need to stop if traffic or pedestrians make it necessary.

Question 3Road Signs and Signals

A white rectangular sign reading "MAXIMUM 50" tells you that:

  1. The top legal speed is 50 km/h Correct answer.
  2. The minimum speed is 50 km/h
  3. The limit applies only after dark
  4. The recommended speed is 50 km/h

Explanation

A maximum speed sign sets the highest speed permitted under good driving conditions. You may legally drive slower, and you must reduce speed when weather, traffic or road conditions require it.

Question 4Road Signs and Signals

A yellow diamond sign showing two children walking tells you that:

  1. A playground is closed
  2. Buses may not stop here
  3. A school crossing is ahead Correct answer.
  4. A school bus stop is ahead

Explanation

The school crossing warning sign is a yellow diamond with figures of children walking. It warns that children may be crossing the road ahead, so you should reduce speed and be ready to stop.

Question 5Road Signs and Signals

A sign showing a large X with the words "RAILWAY CROSSING" warns you that:

  1. A train station is nearby
  2. Trains never use this road
  3. A railway crossing is ahead Correct answer.
  4. You must turn back before the tracks

Explanation

The railway crossing sign warns that tracks cross the road ahead. You should slow down, look both ways and listen, and be prepared to stop if a train is approaching.

Question 6Road Signs and Signals

Most warning signs in Ontario share which shape and colour?

  1. Yellow diamonds with black symbols Correct answer.
  2. Red triangles with white symbols
  3. Blue circles with white symbols
  4. Green rectangles with white symbols

Explanation

Warning signs are yellow diamonds with black symbols or wording. The yellow diamond shape is reserved for warnings so drivers can anticipate a hazard ahead and adjust speed.

Question 7Road Signs and Signals

Orange signs with black symbols are used in Ontario to warn of:

  1. Road construction or maintenance Correct answer.
  2. A school zone
  3. Wildlife on the road
  4. A railway crossing

Explanation

Orange is the colour for construction and maintenance signs. These signs warn of work crews, closed lanes, detours and uneven pavement, so you should slow down and be ready to obey a flag person.

Question 8Road Signs and Signals

A sign showing a black "P" inside a red circle with a diagonal slash means:

  1. Parking is permitted only with a permit
  2. Parking is reserved for delivery vehicles
  3. Parking is not permitted Correct answer.
  4. Parking is permitted for up to one hour

Explanation

A red circle with a diagonal slash through a symbol means the activity shown is prohibited. With a "P" inside, the sign means parking is not permitted; any times or exceptions are shown on a tab beneath it.

Question 9Road Signs and Signals

You are approaching an intersection at the posted speed when the light turns amber. What should you do?

  1. Stop at once, even if you are already in the intersection
  2. Speed up to clear the intersection before the red
  3. Sound your horn and continue at the same speed
  4. Stop if it is safe to do so; otherwise proceed Correct answer.

Explanation

An amber light means the signal is about to turn red. You must stop unless you are so close to the intersection that stopping cannot be done safely, in which case you continue through with care.

Question 10Road Signs and Signals

A flashing red signal at an intersection requires you to:

  1. Slow down and continue without stopping
  2. Stop, then proceed when it is safe Correct answer.
  3. Stop only if another vehicle is near
  4. Wait for a green light before moving

Explanation

A flashing red light has the same meaning as a stop sign. Come to a complete stop, yield to traffic and pedestrians with the right-of-way, and then proceed when the way is clear.

Question 11Road Signs and Signals

A flashing amber (yellow) light at an intersection means:

  1. Treat the intersection as a four-way stop
  2. Stop and wait for a green light
  3. Slow down and proceed with caution Correct answer.
  4. Turn only if the way is clear

Explanation

A flashing amber light means proceed with caution. It is often paired with a flashing red for cross traffic, so slow down, check that the intersection is clear and yield where required.

Question 12Road Signs and Signals

A green arrow pointing left is displayed at the same time as a red light. This means:

  1. You may turn left after yielding to oncoming traffic
  2. Left turns are not permitted
  3. You may drive straight through the intersection
  4. You may turn left; oncoming traffic is stopped Correct answer.

Explanation

A green arrow is a protected movement. When the left arrow is shown with a red light, you may turn left and oncoming traffic is held by a red light, so no yield to opposing traffic is required.

Question 13Road Signs and Signals

A red circle with a white horizontal bar across it means:

  1. Do not enter this road Correct answer.
  2. Stop for a checkpoint ahead
  3. No parking at any time
  4. One-way traffic in your direction

Explanation

The do-not-enter sign is a red circle with a white horizontal bar. It marks the wrong end of a one-way road or an exit ramp, so entering would put you against traffic.

Question 14Road Signs and Signals

A sign that reads "NO STOPPING" means you may not:

  1. Stop for any reason other than traffic or an emergency Correct answer.
  2. Stop except during the hours shown on the sign
  3. Leave your vehicle, but you may wait in it
  4. Park, but you may stop briefly to load passengers

Explanation

No stopping is stricter than no parking: you may not halt there at all, except to obey a traffic signal, a police direction or to avoid a collision. No parking, by contrast, still allows a brief stop to load or unload.

Question 15Road Signs and Signals

A driver's left arm is out the window and bent downward at the elbow, hand pointing down. This signals:

  1. Reversing
  2. A right turn
  3. A stop or a slowdown Correct answer.
  4. A left turn

Explanation

Hand-and-arm signals replace signal lights when they fail. Arm straight out means a left turn, arm bent upward means a right turn, and arm bent downward with the hand pointing down means slowing or stopping.

Question 16Road Signs and Signals

A solid yellow line on your side of the centre line means:

  1. You may pass when the road ahead is clear
  2. Passing is not permitted on your side Correct answer.
  3. You must move left before turning
  4. The lane is reserved for buses

Explanation

A solid yellow line on your side of the centre line means passing is prohibited for traffic in your direction. When one side has a solid line and the other a broken line, only the side with the broken line may pass.

Question 17Road Signs and Signals

A solid white line separates two lanes travelling in the same direction. It means you should:

  1. Use only the right-hand lane
  2. Avoid changing lanes unless necessary Correct answer.
  3. Change lanes freely at any time
  4. Never change lanes at all

Explanation

A solid white line indicates that lane changing is discouraged. You should stay in your lane and cross the line only when a special situation, such as an obstacle or a required turn, makes it necessary.

Question 18Road Signs and Signals

When may you turn right at a red light in Ontario?

  1. Never, unless a police officer directs you to do so
  2. At any time, provided you slow down and signal before turning
  3. Only when a sign or arrow specifically permits the turn
  4. After stopping and yielding, if no sign forbids the turn Correct answer.

Explanation

A right turn on red is allowed after you come to a complete stop, yield to pedestrians and cross traffic, and only where no sign prohibits the turn. Some intersections post a sign banning right turns on red.

Question 19Road Signs and Signals

An overhead signal displays a red "X" above the lane you are using. This means:

  1. You may use the lane only to pass
  2. The lane is for oncoming traffic
  3. The lane is closed to traffic Correct answer.
  4. The lane is reserved for turning vehicles

Explanation

Lane control signals show a red X over a lane that is closed and a green arrow over a lane that is open. You must leave a lane displaying a red X as soon as it is safe to do so.

Question 20Road Signs and Signals

A sign showing a diamond symbol with the letters "HOV" marks a lane reserved for:

  1. Trucks and buses only
  2. Vehicles turning left ahead
  3. Vehicles carrying a minimum number of people Correct answer.
  4. Cyclists only

Explanation

HOV stands for high-occupancy vehicle. The lane may be used only by vehicles carrying at least the number of occupants shown on the sign, and by the exempt vehicles listed on it, such as buses and motorcycles.

Question 21Road Signs and Signals

You may turn left on a red light only when:

  1. Both streets are one-way and no sign forbids it Correct answer.
  2. The intersection has no other vehicles present
  3. You have stopped and there is no oncoming traffic
  4. A green arrow is displayed for your direction

Explanation

A left turn on red is permitted only when you are turning from a one-way street onto a one-way street, you have come to a complete stop, you yield to pedestrians and traffic, and no sign prohibits the turn.

Question 22Road Signs and Signals

On a road without a median, a school bus with its red lights flashing means you must:

  1. Slow down and pass with caution
  2. Change lanes and continue driving
  3. Stop only if children are visible
  4. Stop until the lights stop flashing Correct answer.

Explanation

When a school bus displays flashing red lights, traffic in both directions on an undivided road must stop and stay stopped until the lights stop flashing. Passing a stopped school bus with red lights flashing carries heavy penalties.

Question 23Road Signs and Signals

A sign with three circular arrows warns of a roundabout, where you must:

  1. Turn back if the circle is occupied
  2. Yield to traffic already in the circle Correct answer.
  3. Take the right-of-way from circulating traffic
  4. Stop before entering the circle

Explanation

At a roundabout, traffic already circulating has the right-of-way. You slow down on approach, yield to vehicles in the circle and to pedestrians at the crosswalks, then enter when there is a safe gap.

Question 24Road Signs and Signals

A flashing green light at an Ontario intersection means:

  1. You may turn left while oncoming traffic is stopped Correct answer.
  2. You must yield before turning left
  3. The signal is about to change to red
  4. The signals are not working

Explanation

In Ontario, a flashing green light is an advanced green used in some municipalities. It lets you turn left, go straight or turn right while opposing traffic is held at a red light.

Question 25Road Signs and Signals

A police officer waves you through an intersection while the light facing you is red. What must you do?

  1. Stay stopped, because the red light takes priority
  2. Proceed only after the officer has left the scene
  3. Wait for the light to turn green before moving
  4. Follow the officer's direction, which overrides the light Correct answer.

Explanation

A police officer directing traffic has authority over signs and signals. When an officer signals you to proceed, you follow that direction even though the light is red, while watching for other traffic and pedestrians.

Question 26Road Signs and Signals

In Ontario, what shape is a stop sign?

  1. Octagonal Correct answer.
  2. Circular
  3. Triangular
  4. Rectangular

Explanation

Stop signs are octagons with a red background and white lettering, a shape used only for stop signs so they are recognizable from behind or in poor conditions. You must come to a complete stop at the stop line or crosswalk before proceeding.

Question 27Road Signs and Signals

You are approaching a yield sign at an intersection. What must you do?

  1. Sound your horn and continue at the same speed
  2. Accelerate to merge ahead of the cross traffic
  3. Slow down and yield to traffic on the cross road Correct answer.
  4. Come to a complete stop before entering the intersection

Explanation

A yield sign is an inverted triangle with a red border. It requires you to slow down and give the right of way to traffic already on the road you are entering, stopping only if traffic makes that necessary.

Question 28Road Signs and Signals

A white rectangular sign with black lettering reading "MAXIMUM 50" means:

  1. The recommended speed in good weather
  2. The legal speed limit is 50 km/h Correct answer.
  3. The minimum speed is 50 km/h
  4. Trucks must travel at 50 km/h

Explanation

White signs with black lettering are regulatory, and MAXIMUM 50 sets the legal speed limit at 50 km/h. Exceeding that speed is an offence even if traffic and weather seem to allow more.

Question 29Road Signs and Signals

A blue sign with a white letter "H" on it indicates:

  1. A heliport only
  2. A hospital nearby Correct answer.
  3. A hostel ahead
  4. A highway maintenance yard

Explanation

Blue signs provide motorist services, and the white H marks a hospital, often guiding drivers toward emergency care. Other service symbols on blue signs include fuel, food and accommodation.

Question 30Road Signs and Signals

A yellow diamond sign showing the silhouette of a deer warns that:

  1. Livestock must be kept off the road
  2. A wildlife park entrance is ahead
  3. Hunting is not permitted in the area
  4. Deer may cross the road ahead Correct answer.

Explanation

The deer silhouette is a hazard warning: deer often move at dawn and dusk and can step onto the road without warning. Reduce speed and scan the shoulders where this sign is posted.

Question 31Road Signs and Signals

A broken (dashed) yellow line on your side of the centre line means:

  1. You may park on the shoulder
  2. The road becomes one-way ahead
  3. You must not change lanes
  4. Passing is allowed when it is safe Correct answer.

Explanation

A broken yellow line separates traffic moving in opposite directions and may be crossed to pass when the way is clear and passing is otherwise legal. The line becomes solid where passing is unsafe.

Question 32Road Signs and Signals

A pedestrian signal displays an upraised hand symbol. This means:

  1. Pedestrians may cross immediately
  2. Do not start to cross the road Correct answer.
  3. The signal is out of order
  4. Turning vehicles must stop

Explanation

An upraised hand means pedestrians must not begin crossing; anyone already in the crosswalk should finish without delay. The walking-person symbol is the display that permits pedestrians to start.

Question 33Road Signs and Signals

A solid green traffic light means:

  1. Stop and check for traffic before proceeding
  2. Proceed if the intersection is clear Correct answer.
  3. Proceed only if you are turning right
  4. Yield to traffic entering from the left

Explanation

A green light permits you to go straight or turn, provided the intersection is clear and you yield to pedestrians and, when turning left, to oncoming traffic. It does not give you the right to block the intersection.

Question 34Road Signs and Signals

An overhead signal shows a green arrow pointing down above your lane. This means:

  1. The lane is open and you may use it Correct answer.
  2. The lane is reserved for buses only
  3. The lane will close within 100 metres
  4. You must change lanes to the right

Explanation

Overhead lane-control signals manage traffic in each lane: a green down arrow means the lane is open, while a red X means it is closed. Obey the display for your lane rather than the one beside it.

Question 35Road Signs and Signals

You approach an intersection where the traffic lights are completely dark because of a power failure. You should:

  1. Wait until the lights come back on
  2. Treat the intersection as uncontrolled and go first
  3. Treat the intersection as an all-way stop Correct answer.
  4. Proceed through the intersection without slowing

Explanation

When signals are not working, the intersection becomes an all-way stop. Every driver must stop and take turns in the order of arrival.

Question 36Road Signs and Signals

A double solid yellow line in the centre of the road means:

  1. Passing is allowed for traffic on both sides
  2. You may cross the line to pass a slow vehicle
  3. Passing is not allowed in either direction Correct answer.
  4. The road is one-way in both lanes

Explanation

Two solid yellow lines prohibit passing for traffic in both directions. You may still cross them to turn into a driveway or side road where it is safe and permitted.

Question 37Road Signs and Signals

A yellow diamond sign showing a squiggly arrow indicates:

  1. A divided highway begins
  2. A one-way road ahead
  3. An exit ramp ahead
  4. A winding road ahead Correct answer.

Explanation

The wavy arrow warns of a series of curves. Slow down before the first curve and keep well within your lane.

Question 38Road Signs and Signals

A yellow diamond sign showing a road outline that pinches inward warns of:

  1. A narrow bridge or structure ahead Correct answer.
  2. A railway crossing on a bridge
  3. A construction site with a reduced lane width
  4. A tunnel with no lighting

Explanation

The narrowing outline warns that the roadway ahead is more confined than the approach, often where a bridge or culvert crosses. Slow down and be ready to yield if the space is tight.

Question 39Road Signs and Signals

Signs with a fluorescent yellow-green background are most often used to warn of:

  1. Wildlife areas
  2. Highway maintenance work
  3. Ferry terminals
  4. School zones and school crossings Correct answer.

Explanation

Fluorescent yellow-green is reserved for school zones and school crossings so the signs stand out to drivers. Reduce speed and watch for children and crossing guards.

Question 40Road Signs and Signals

A yellow diamond sign showing a symbol of an airplane warns that:

  1. A weather station is ahead
  2. An airport or aircraft flying area is nearby Correct answer.
  3. A parachute landing zone is ahead
  4. A military base is ahead

Explanation

The airplane symbol warns that aircraft may fly low over the road, usually near an airport. Stay alert and avoid stopping where planes pass close overhead.

Question 41Road Signs and Signals

A white sign with a red circle and a diagonal slash over a U-shaped arrow means:

  1. The road curves back on itself ahead
  2. A detour route begins here
  3. U-turns are not allowed here Correct answer.
  4. U-turns are permitted at the next intersection

Explanation

A red circle with a diagonal slash marks a prohibition, so the manoeuvre pictured is forbidden at that location. Here, U-turns are not allowed.

Question 42Road Signs and Signals

A black arrow on a white rectangular sign bearing the words "ONE WAY" means:

  1. Traffic must turn at the next corner
  2. Traffic flows only in the direction shown Correct answer.
  3. The road is closed in both directions
  4. The lane is reserved for buses

Explanation

The ONE WAY sign shows the only permitted direction of travel on that road. Facing against the arrow means you are going the wrong way and must turn around.

Question 43Road Signs and Signals

A yellow diamond sign showing two arrows pointing in opposite directions warns that:

  1. Traffic will merge from the right
  2. A divided highway begins ahead
  3. Passing is permitted on both sides
  4. Two-way traffic is ahead Correct answer.

Explanation

This warning tells you the road ahead carries traffic in both directions, often where a one-way street or divided highway ends. Keep to the right and expect oncoming vehicles.

Question 44Road Signs and Signals

A yellow diamond sign showing a car with wavy skid marks behind it warns of:

  1. A car wash facility
  2. A vehicle inspection station
  3. A gravel road starting ahead
  4. A slippery road surface when wet Correct answer.

Explanation

The skidding car warns that the surface loses traction when wet, icy or covered in loose material. Reduce speed, brake gently and leave extra following distance.

Question 45Road Signs and Signals

A wide solid white line painted across your lane at an intersection is:

  1. The edge of a bicycle lane
  2. A marking that may be crossed at any time
  3. A stop line where you must stop Correct answer.
  4. A guide for parking at the curb

Explanation

A wide solid white line across your lane marks the place to stop for a stop sign, a red light or a pedestrian crossing. Stopping behind it keeps the crosswalk and cross traffic clear.

Question 46Road Signs and Signals

A warning sign shows a curve, and a yellow plate below it reads "30 km/h" while the posted limit is 80 km/h. Which statement is correct?

  1. It is the recommended safe speed for the curve Correct answer.
  2. It applies only to vehicles towing trailers
  3. It is the legal maximum speed for the whole road
  4. It is the minimum speed allowed in the curve

Explanation

A yellow plate with a speed gives an advisory speed, showing a speed considered safe for the hazard in good conditions. It is not a legal maximum, but driving faster than is safe can still result in a charge.

Question 47Road Signs and Signals

You approach a railway crossing marked only by a crossbuck sign, with no lights or gates. You must:

  1. Come to a complete stop every time before the tracks
  2. Slow down, look both ways, and cross only when it is safe Correct answer.
  3. Cross without slowing because trains must yield to road traffic
  4. Stop only if you can see a train within 100 metres

Explanation

At an unprotected crossing you must slow down, look and listen in both directions, and cross only when no train is coming; a full stop is required only when a train is approaching or a stop sign is posted. Trains cannot stop quickly and always have the right of way.

Question 48Road Signs and Signals

A white arrow painted on the pavement of your lane curves left and the word "ONLY" is printed beside it. In that lane you must:

  1. Change lanes before the intersection
  2. Continue straight or turn left
  3. Turn left from that lane Correct answer.
  4. Turn left only after stopping completely

Explanation

Pavement arrows show the movement each lane is designated for, and the word ONLY removes any other choice. If you intend to go straight, change lanes before reaching the intersection.

Question 49Road Signs and Signals

You approach a pedestrian crossover marked by overhead flashing amber lights. A pedestrian is waiting at the curb. You must:

  1. Continue if the pedestrian has not yet stepped onto the road
  2. Stop and let the pedestrian cross Correct answer.
  3. Slow down and drive around the pedestrian
  4. Flash your headlights and proceed

Explanation

At a pedestrian crossover you must yield to pedestrians who are crossing or waiting to cross, so a person at the curb has the right of way. Once stopped, remain stopped until the pedestrian has cleared your path.

Question 50Road Signs and Signals

A yellow diamond sign shows a symbol of a traffic light on a road where the intersection is hidden by a curve. You should:

  1. Speed up to get through before the light changes
  2. Assume the light will be green and keep your speed
  3. Slow down and be prepared to stop Correct answer.
  4. Move toward the centre of the road for a better view

Explanation

The traffic-light symbol warns that a signalized intersection is ahead, possibly out of sight because of a curve or hill. Reduce speed so you can stop safely if the signal is red.
