Questions (6)
1. Under all conditions you should drive at a speed that will allow you to…?
- Stop within 60 m
- Stop within a safe distance ✓
- Stop within 150 m
- Stop within 90 m
Answer: B. Stop within a safe distance
Under all conditions, drive at a speed that lets you stop within a safe distance. The handbook's general driving guidance says to keep a cushion of space and enough distance to stop safely if the vehicle ahead brakes suddenly. Its towing guidance also says to maintain a speed that lets you slow down and stop smoothly in any situation. That is a flexible, conditions-based standard, so it matches stopping within a safe distance rather than a fixed metre figure.
2. It is more dangerous to drive at the maximum speed limit at night than during the day because…?
- The roadways are more apt to be slippery at night
- Some drivers unlawfully drive with parking lights only
- You cannot see as far ahead, even with headlights ✓
- Your reaction time is slower at night
Answer: C. You cannot see as far ahead, even with headlights
It is more dangerous to drive at the maximum speed limit at night because you cannot see as far ahead, even with headlights. The handbook says plainly that at night, and in rain, snow or fog, your headlights don't let you see as far ahead as you can in daylight. It tells you to slow down at night, especially on unlit roads. At the maximum speed limit your stopping distance can stretch beyond what your headlights show you, so you may not have room to stop safely for something that only appears at the edge of your lights.
3. In good weather conditions, you are required to keep a safe distance behind the vehicle in front of you. You should keep at least…?
- A one second gap to the other vehicle
- A two second gap to the other vehicle ✓
- Five car lengths behind the other vehicle
- Seven car lengths behind the other vehicle
Answer: B. A two second gap to the other vehicle
You should keep at least a two-second gap to the vehicle in front of you. The handbook gives a general rule for following another vehicle: leave enough space to stop safely if it brakes suddenly. It states that a safe following distance is at least two seconds behind the vehicle ahead, which also lets you see around it. The handbook notes this two-second rule is a minimum for ideal driving conditions, and you need more space in situations such as bad weather.
4. Unless otherwise posted, the maximum speed limit allowed on the highway outside of city, town and village is…?
- 60 km/h
- 50 km/h
- 100 km/h
- 80 km/h ✓
Answer: D. 80 km/h
Unless a sign says otherwise, the maximum speed on a highway outside cities, towns and villages is 80 km/h. The handbook states that where no speed limit is posted, the top speed is 50 km/h in cities, towns and villages and 80 km/h everywhere else. Since the question asks about a highway outside those built-up areas, the default limit that applies is 80 km/h. The same passage also reminds you that the posted maximum is a ceiling, not a target, and you should slow down in bad weather, heavy traffic or construction zones.
5. While you are driving with a G1 license, you must not drive on 400-series highways with a posted speed limit over:
- 80km/h ✓
- 60km/h
- 50km/h
- 70km/h
Answer: A. 80km/h
With a G1 licence, you must not drive on a 400-series highway whose posted speed limit is over 80 km/h. The Level One section of the handbook lists the rules that apply while you hold a G1 licence. It states that you cannot drive on 400-series highways when the posted speed limit is over 80 km/h. That makes 80 km/h the cutoff named in the rule, so the correct choice is the one giving 80 km/h.
6. Where there are no posted speed limits, the maximum speed in cities, towns and villages is…?
- 30km/h
- 40km/h
- 50km/h ✓
- 60km/h
Answer: C. 50km/h
Where there are no posted speed limits, the maximum speed in cities, towns and villages is 50 km/h. The handbook states the default limit plainly: with no signs posted, the top speed is 50 km/h in cities, towns and villages and 80 km/h elsewhere. That default applies unless a sign lowers or raises it, so in built-up areas you hold to 50 km/h and adjust downward for weather, traffic or construction. The same passage reminds you to always pick a speed that lets you stop safely, which may be well under the maximum.
