Questions (21)
1. ____ are the cause of more than half of all accident-related truck driver deaths.
Truck rollovers ✓
Motorcycles
Slippery roads
Pedestrians
Answer: A. Truck rollovers
Truck rollovers are the cause of more than half of all accident-related truck driver deaths. The combination-vehicle section says outright that over half of truck driver deaths in crashes come from truck rollovers. It explains that a high center of gravity makes a truck easier to turn over, and that fully loaded rigs are far more likely to roll over than empty ones. It also says rollovers happen when you turn too fast, and it advises keeping cargo low and centered and driving slowly around corners, ramps, and off ramps. That direct statement supports choosing truck rollovers.
Students should board the school bus slowly, in single file, using the handrail. The handbook's loading procedure tells the driver to have students board slowly, in single file, and to use the handrail. The same section also tells you to count students at the stop and make sure all of them get on, and to check the mirrors again before moving. Boarding in a single line keeps the group orderly and lets you keep track of who is coming up the steps, which fits the counting and mirror-check steps the handbook lays out.
Only use the side mirrors on the driver’s side of the vehicle.
Use both side mirrors. ✓
Not use a helper.
Answer: B. Use both side mirrors.
When backing a truck, you should use both side mirrors. The handbook tells you to check the outside mirrors on both sides frequently while backing, and it lists using mirrors on both sides as one of its basic backing safety rules. Since you cannot see everything behind the vehicle, watching both mirrors is how you keep track of your path and catch steering errors early. Backing toward the right side is described as very dangerous because you cannot see as well in that direction, which is why the handbook also favors backing toward the driver's side.
4. When approaching a railroad crossing while transporting chlorine:
You must stop before crossing the tracks. ✓
You must reduce your speed before crossing the tracks.
You may proceed across the tracks without stopping if no warning lights are flashing.
Answer: A. You must stop before crossing the tracks.
When you are hauling chlorine, you must stop before the railroad tracks. The handbook says to stop before a railroad crossing if your vehicle carries any amount of chlorine. It also says to stop 15 to 50 feet before the nearest rail, then cross only when you are sure no train is coming and you can clear the tracks without stopping. The handbook's stop requirement is based on carrying chlorine, so slowing down or rolling across when no warning lights are flashing does not meet the rule.
Answer: C. There is any imminent danger of collision.
You must evacuate a school bus when there is an imminent danger of collision. The handbook lists the situations that require a mandatory evacuation, and an imminent danger of collision is one of them. The list also covers fire or the threat of fire, a stall on or next to a railroad-highway crossing, a bus position that could change and increase danger, and a need to clear the bus quickly because of a hazardous materials spill. In each of these, staying on the bus is riskier than getting everyone off, so the driver acts rather than waiting.
Can only use a hands-free mobile phone while driving. ✓
Can only use a cell phone on rural roads.
Can use a cell phone at night.
Answer: B. Can only use a hands-free mobile phone while driving.
You may only use a hands-free mobile phone while driving a commercial motor vehicle. The handbook says commercial motor vehicle drivers are restricted from using hand-held mobile phones. If you use a phone while driving, the permitted choice is a hands-free phone located close to you and operable within the rule for voice communication. It also warns against reaching for a phone unsafely, even when you intend to use the hands-free feature, and against typing or reading text messages. That supports the hands-free-only answer.
10. A truck may need to be under the legal maximum weight limit when being driven:
On a flat road.
On a mountainous road. ✓
In heavy traffic.
At night.
Answer: B. On a mountainous road.
A truck may need to run below the legal maximum weight on a mountainous road, because a grade can make a legal load unsafe to handle. The handbook makes the driver responsible for staying within legal weight limits and warns that you must keep GVWR, GCWR and axle weights inside those limits. Its Section 3 review list then asks you to name situations where legal maximum weights may not be safe, which tells you a load can be legal on paper and still be too much for the road you are on. A mountain grade is that kind of condition. The other choices describe ordinary driving settings rather than a road that pushes a legal load past what the truck can handle safely.
