2. You are prohibited from operating a commercial vehicle if you've been on-duty for how many hours in a week?
80 hours
60 hours
50 hours
70 hours ✓
Answer: D. 70 hours
You are prohibited from driving after 70 hours on-duty in a seven-day period. The handbook describes a seven-day cycle and a 14-day cycle. For the seven-day cycle, it says a driver cannot drive after being on-duty for 70 hours in seven consecutive days. It also says a driver must not keep driving after accumulating 70 on-duty hours without 24 consecutive hours off-duty. That makes 70 hours the weekly on-duty point tied to the prohibition in the question; the 14-day figure is 120 hours, which is a different cycle.
3. After at least eight hours off-duty, a school bus driver cannot drive more than how many hours?
15 hours
10 hours
12 hours
13 hours ✓
Answer: D. 13 hours
After at least eight hours off-duty, the driver cannot drive more than 13 hours. The handbook's mandatory off-duty section sets the limit directly: once a driver has had a period of at least eight hours off-duty, driving is capped at 13 hours. The same passage also caps driving after 14 hours on-duty and after 16 hours have elapsed, so the 13-hour figure is the one that answers this question about driving hours.
4. If your truck is transporting cargo, you must check the securement of the cargo within the first ______ of the trip.
80 km ✓
120 km
320 km
240 km
Answer: A. 80 km
You must re-check the cargo securement no more than 80 km from the point where the cargo was loaded. The handbook says the load has to be inspected before you drive, and then re-checked not more than 80 km from where it was loaded. That first short interval is the one being asked about here. Longer intervals, such as hours of driving, kilometres driven or a change of duty status, apply to the re-inspections that come after this initial check, not to the first one.
5. If you're approaching a railway crossing at which a signal device or flagperson is warning of an approaching train, you must
slow down and proceed with caution.
cross the tracks as quickly as possible.
stop at least 1.5 metres (5 feet) from the nearest rail.
stop at least 5 metres (15 feet) from the nearest rail. ✓
Answer: D. stop at least 5 metres (15 feet) from the nearest rail.
You must stop at least 5 metres (15 feet) from the nearest rail when a signal device or flagperson warns that a train is coming. The handbook says that when a train is coming you stop at least five metres back from the nearest rail or gate, and you wait until you are certain the train or trains have passed before crossing. It also tells you never to race a train to a crossing. With a signal or flagperson warning you, the way is not clear, so the five-metre stopping distance is what applies. Keeping that space back from the rail is the gap the handbook sets.
6. Provincial/Territorial authorities recommend that every commercial vehicle carry
reflectors.
a first-aid kit. ✓
water bottles.
a fire extinguisher.
Answer: B. a first-aid kit.
A well-stocked first-aid kit is the recommended item every commercial vehicle should carry. The handbook says St. John Ambulance advises drivers to keep a full first-aid kit on board and learn how to use it. It also suggests first-aid reading or a course, and the collision section describes treating injuries until help arrives. That directly supports a first-aid kit as the recommended carry item. The passages do not make the same kind of carry recommendation for reflectors, water bottles or a fire extinguisher.
7. Who can demand you to appear at a truck inspection station?
A traffic officer ✓
A pedestrian
A passenger
A fellow driver
Answer: A. A traffic officer
A traffic officer — a police officer or appointed ministry officer — can require you to appear at a truck inspection station. The truck handbook says any police officer or appointed ministry officer may perform a safety inspection at any time and any location. Those officers may also require you to drive to the nearest inspection station. That authority is given to enforcement officers, not to ordinary road users, so a traffic officer is the correct choice.
9. Under Ontario law, when a school bus stops with its red signals flashing, other drivers must
stop before reaching the bus and remain stopped. ✓
stop before reaching the bus and then proceed with added care.
sound their horn and proceed with added care.
slow down and pass with added care.
Answer: A. stop before reaching the bus and remain stopped.
You must stop before reaching the school bus and remain stopped until its red lights stop flashing and the stop arm folds away. The handbook says you must stop whenever you approach a stopped school bus with its upper alternating red lights flashing, whether you are behind it or coming from the front. It also says to remain stopped until the stop-sign arm folds away and all lights stop flashing, and that failing to stop is illegal. That is why the correct action is to stop before reaching the bus and stay stopped, not just slow down or continue after a brief pause.
Do all of the above: sound your horn, use a guide when one is available, and keep your backing away from the blind side. The handbook lists several precautions before reversing: turn off the phone or radio, open the windows, turn on the four-way flashers and sound the horn. It also tells you to walk around the vehicle first and to keep the blind spot in mind. A responsible guide helps by watching the area behind you and your blind-spot zone, warning you if pedestrians or vehicles move into your path. Since each of these is part of the same backing procedure, the complete answer is to do all of them, not just one.
