  1. 1 of 16 · Speed limits

    No sign is posted on a street in a town. What is the speed limit?

    • A.40 km/h
    • B.60 km/h
    • C.80 km/h
    • D.50 km/hAnswer

    Explanation: Unless a sign says otherwise, the limit is 50 km/h in cities, towns, villages and other built-up areas.

  2. 2 of 16 · Speed limits

    What is the default speed limit on a highway outside a built-up area when no sign is posted?

    • A.80 km/hAnswer
    • B.90 km/h
    • C.100 km/h
    • D.70 km/h

    Explanation: Outside cities, towns and villages the default limit on Ontario highways is 80 km/h unless a sign shows a different speed.

  3. 3 of 16 · Speed limits

    What happens to speeding fines in a construction zone when workers are present?

    • A.They stay the same as elsewhere
    • B.They are reduced because of the lower limit
    • C.They are doubledAnswer
    • D.They are replaced by an automatic licence suspension

    Explanation: Speeding fines are doubled in a construction zone when workers are present, so obey the posted reduced limit.

  4. 4 of 16 · Speed limits

    You are caught driving 50 km/h over the limit. What happens at the roadside?

    • A.A 30-day licence suspension and 14-day vehicle impoundmentAnswer
    • B.A written warning and a court date
    • C.A 7-day licence suspension only
    • D.Demerit points but no suspension

    Explanation: Driving 50 km/h or more over the limit is stunt driving: an immediate 30-day roadside licence suspension and a 14-day vehicle impoundment, plus penalties in court.

  5. 5 of 16 · Speed limits

    An orange triangle with a red border on the back of a vehicle tells you that it travels at:

    • A.60 km/h or less
    • B.40 km/h or lessAnswer
    • C.80 km/h or less
    • D.20 km/h or less

    Explanation: The orange slow-moving-vehicle sign means the vehicle travels at 40 km/h or less, so slow down early when you see one.

  6. 6 of 16 · Speed limits

    In which of these conditions should you avoid using cruise control?

    • A.On a dry, straight highway in light traffic
    • B.On wet, icy or slippery roadsAnswer
    • C.On a long trip where you want steady fuel economy
    • D.On a road where you want to avoid drifting over the limit

    Explanation: Cruise control is a useful aid on good roads, but it should be switched off in adverse conditions such as wet, icy or slippery roads, in heavy traffic, and whenever you are feeling fatigued — all situations where you need to be the one controlling the speed.

  7. 7 of 16 · Speed limits

    What happens if you are caught driving with a speed measuring warning device (a radar detector)?

    • A.Nothing — they are legal as long as you stay within the limit
    • B.The device is taken away, but there is no fine
    • C.You are fined and given demerit pointsAnswer
    • D.A warning only, for a first offence

    Explanation: Speed measuring warning devices are illegal in Ontario. Simply having one in the vehicle is the offence — you do not have to be speeding — and it brings both a fine and demerit points.

  8. 8 of 16 · Speed limits

    Where should you expect a posted speed limit lower than the road around it?

    • A.In school zones and construction zonesAnswer
    • B.On every two-lane road
    • C.On bridges
    • D.On roads with street lighting

    Explanation: School zones and construction zones often carry a lower posted limit than the road they sit on, to protect children and the people working on or near the road. Watch for the signs — the lower number is the one that applies.

  9. 9 of 16 · Speed limits

    On a road posted below 80 km/h, how far over the limit is already stunt driving?

    • A.20 km/h or more
    • B.30 km/h or more
    • C.40 km/h or moreAnswer
    • D.50 km/h or more, on any road

    Explanation: The threshold is lower on slower roads. Anywhere the posted limit is under 80 km/h, 40 km/h over is enough to be charged with stunt driving; on faster roads the general threshold of 50 km/h over applies.

  10. 10 of 16 · Speed limits

    At what speed are you charged with stunt driving anywhere in Ontario, whatever the posted limit?

    • A.120 km/h or more
    • B.140 km/h or more
    • C.150 km/h or moreAnswer
    • D.There is no fixed speed — only the margin over the limit counts

    Explanation: 150 km/h or more is stunt driving anywhere in the province. That includes the stretches of freeway posted at 110 km/h, where 150 is “only” 40 over and would otherwise fall under the general threshold.

  11. 11 of 16 · Speed limits

    Which of these counts as stunt driving even if you never exceed the speed limit?

    • A.Driving in the left-hand lane of a freeway
    • B.Driving in a way that prevents other vehicles from passingAnswer
    • C.Braking gently to let a tailgater go by
    • D.Driving slightly below the posted limit

    Explanation: Stunt driving is not only about speed. Deliberately blocking another vehicle from passing counts, and so do intentionally cutting someone off and intentionally driving too close to a vehicle, a pedestrian or a fixed object.

  12. 12 of 16 · Speed limits

    Besides lengthening your stopping distance, what else does speeding do?

    • A.It sharpens your reaction time, because you concentrate harder
    • B.It reduces your field of vision, so hazards appear laterAnswer
    • C.It has no effect on what you can see
    • D.It makes your headlights reach further

    Explanation: Speed narrows what you take in at the edges of your vision, so a hazard is noticed later — at the same moment as the longer braking distance is leaving you less room to do anything about it. The two effects compound.

  13. 13 of 16 · Speed limits

    On a road posted at 100 km/h, how much higher is the risk of death or serious injury in a collision at 50 km/h or more over that limit?

    • A.About twice as high
    • B.About five times as high
    • C.About eleven times as highAnswer
    • D.About the same — the limit is what matters, not the margin

    Explanation: Ontario data from 2013 to 2017 puts the risk of fatality or serious injury 11 times higher in collisions at 50 km/h or more over a 100 km/h limit than in collisions at or below the posted limit.

  14. 14 of 16 · Speed limits

    Ontario speeding fines are charged per kilometre per hour over the limit. At the $7 rate, what is the fine for driving 40 km/h over?

    • A.$140
    • B.$200
    • C.$280Answer
    • D.$400

    Explanation: The fine is a rate per km/h over, multiplied by how far over you were: $7 × 40 = $280. The rate itself climbs with the margin, so the fine grows faster than the speed does.

  15. 15 of 16 · Speed limits

    Which of these is street racing?

    • A.Accelerating briskly away from a green light
    • B.Two or more drivers driving in a way that shows they are competingAnswer
    • C.Passing a slow vehicle on a two-lane road
    • D.Driving at the maximum posted limit

    Explanation: Street racing covers two or more vehicles driven in a way that indicates the drivers are competing, chasing another vehicle, and changing lanes repeatedly at high speed while weaving through traffic.

  16. 16 of 16 · Speed limits

    You should under all conditions drive at a speed which will allow you to:

    • A.Stop within 150 metres (500 feet).
    • B.Stop within 90 metres (300 feet).
    • C.Stop within 60 metres (200 feet).
    • D.Stop within a safe distance.Answer

    Explanation: There is no fixed distance to memorise. The number on the sign is a maximum for good conditions, not a target: in bad weather, heavy traffic or a construction zone the safe speed is lower, and the right speed is always the one that lets you stop safely for whatever appears.
