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.
You will hear two short blasts of the train's horn.
There will always be flashing warning lights.
Answer: B. You may not hear a train as it approaches.
You may not hear a train as it approaches, so treat an active crossing as a place where a train can come without an audible warning. The handbook tells drivers not to count on hearing a train. Some trains do not sound horns at certain crossings, and noise inside your cab can keep you from hearing a horn until the train is very close. That is why you should approach every crossing expecting a train and look both ways instead of waiting for an audible warning. This directly supports the idea that a train may come without you hearing it.
3. If approaching a railroad crossing that is being approached by a train, you should:
Try to cross the tracks quickly.
Drive around any lowered gates.
Stop and wait for the train to pass before beginning across the tracks. ✓
Answer: C. Stop and wait for the train to pass before beginning across the tracks.
Stop and wait for the train to pass before you begin crossing the tracks. The handbook says flashing red lights and bells at a crossing mean a train is approaching, and you must stop and yield the right of way. It tells you to remain stopped until the gates go up and the lights stop flashing, then proceed only when it is safe. It also warns against driving around a gate that stays down. Waiting keeps you from starting across while the train is still coming.
Dry bulk tanks usually have a high center of gravity. The handbook section on cargo needing special attention says dry bulk tanks require extra care because their center of gravity is high and the load can shift. That high, shifting weight makes the vehicle less stable, so the handbook says to be very cautious and go slowly around curves and sharp turns. The answer follows directly from that warning: dry bulk tanks usually have a high center of gravity.
Are not controlled by any type of traffic control device. ✓
Have gates that lower when trains are approaching.
Should never be crossed by a CMV.
Answer: B. Are not controlled by any type of traffic control device.
Passive railroad crossings are not controlled by any type of traffic control device. The handbook defines a passive crossing as one with no traffic control device installed at the crossing. That is why the driver must recognize it, look for a train, and judge whether there is enough clear space to cross safely; the decision to stop or go is left to the driver. The yellow advance warning signs, pavement markings, and crossbucks help you notice the crossing, but they do not control traffic the way active devices do.
Do not need to stop, but must reduce their speed to 25 mph below the posted speed limit.
Do not need to stop, but must open the door to listen for trains.
Must stop and check for any approaching trains. ✓
Answer: D. Must stop and check for any approaching trains.
Bus drivers must stop at railroad crossings and check for any approaching trains. The handbook tells school bus drivers not to cross the tracks unless they can see far enough down the track to know for certain that no train is approaching. It also says to look and listen even when active signals indicate the tracks are clear, because signals alone are not enough. That means the bus driver must stop and make the check before committing the bus to the crossing, rather than rolling through on the signal.
9. Which of the following is not an example of a driving hazard?
An accident on the roadway
An open road ✓
A police car assisting a motorist on the side of the road
An ice cream truck
Answer: B. An open road
An open road is not an example of a driving hazard. The handbook defines a hazard as any road condition or other road user that could be a possible danger. It also tells drivers to look for an open spot away from other traffic, which treats open space as the safer condition rather than the danger. An accident on the roadway is a road condition you would need to react to. A police car helping a motorist is an emergency vehicle stopped at the roadside, and the handbook says to approach that situation with caution. An ice cream truck is another vehicle and driver on the road. The open road is therefore the choice that is not itself a hazard.
10. If a vehicle gets stuck on a railroad track, the driver should:
Stay in the vehicle and try to restart the vehicle.
Get out of the vehicle and walk away from the tracks. ✓
Try to flag down another vehicle to give them a push.
Wait in the vehicle for a law enforcement officer to arrive.
Answer: B. Get out of the vehicle and walk away from the tracks.
Get out of the vehicle and walk away from the tracks. The handbook says that if you get stuck on the tracks for any reason, you should get out of the vehicle and get away from the tracks. It then tells you to check signposts or the signal housing for emergency notification information, call 911 or another emergency number, and give the crossing location using landmarks, especially the DOT number if it is posted. That matches getting out and walking away from the tracks. Staying with the vehicle or waiting for someone else is not what the passage directs.
