A passenger tucks the shoulder belt behind their back because it is uncomfortable. What does the manual say?
- It is fine on short trips

- Into a garage
- Out of a driveway
You are backing out of a driveway onto a two-lane street. How far may you back?
- Into any lane with no traffic
- Only into the nearest lane
- Across both lanes if clear
- To the far curb
Backing straight up, which way do you turn the wheel for a small correction?
- You should not turn it at all
- The way you want the back to go
- Always to the right
- Opposite to where you want to go
Starting, steering and stopping: key rules to remember
Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗
Starting your vehicle (Ch. 3)
- Walk around the vehicle before getting in: check for children, pedestrians, oncoming traffic and obstructions.
- Seat: see over the wheel, reach all controls, arms relaxed. With a steering-wheel air bag, Transport Canada recommends sitting at least 25 cm (10 in.) back from the wheel while still reaching the brake.
- Mirrors: inside mirror to see as much behind as possible; side mirrors to reduce blind spots.
- Seat belt is the law; lap belt low and snug over hips, shoulder belt across chest and shoulder; never behind your back or under your arm. Wear it even with air bags.
Head restraint; pulling out
- Centre of the head restraint level with the top of your ears; if it tilts, less than 10 cm (4 in.) between head and restraint is ideal.
- Before pulling out: use mirrors and also shoulder check.
- Pulling out from the right side of the road: left signal. From the left side of a one-way road: right signal.
Transmissions
- P locks the transmission; used for starting and parking. R reverse. N out of gear. D normal driving. 3,2,1 stop upshifting (hills). Overdrive: higher speeds, saves fuel.
- Manual: start with gearshift in neutral and clutch fully pressed. Friction point = where engagement is first felt. Lugging vs racing. "Riding the clutch" (foot left on pedal) wears the clutch. Stay in gear going downhill; don't press the clutch too early when stopping (coasting).
Steering
- Hands at 9 o'clock (left) and 3 o'clock (right). Use hand-over-hand for turning and recovery.
Accelerating
- Accelerate smoothly; never exceed the posted limit; don't spin tires; driving well below the limit is also a hazard — pull over to let traffic pass if needed.
Stopping distance
- Perception time about 3/4 second; average reaction time 3/4 second.
- Total stopping distance = perception distance + reaction distance + braking distance.
- Chart (smooth dry pavement): 50 km/h ≈ 37 m total; 80 km/h ≈ 76 m; 100 km/h ≈ 108 m; 110 km/h ≈ 126 m; 30 km/h ≈ 18 m.
Braking techniques
- Brake early; ease off the gas first; ease up slightly just before stopping for smoothness.
- Threshold braking for quick stops: brake almost to lock-up; if wheels lock, ease up. Locked wheels = loss of steering.
Reversing
- Look behind; walk around first if backing out of a driveway.
- Straight back: left hand at top of wheel, look over right shoulder through rear window; turn the wheel the way you want the back of the vehicle to go.
- Backing left: look over left shoulder; backing right: over right shoulder. The front swings the opposite way.
- Back only into the nearest lane; backing across a centre line is illegal. In urban areas you may not back into an intersection or crosswalk. Keep to walking speed. White back-up lights = vehicle in reverse.
