Wyoming CDL: Passenger Vehicles Practice Test

Not quite. The answer is you are driving too fast.

If your bus is leaning toward the outside of a banked curve, you are driving too fast and should slow down before your bus rolls over or starts to skid. The posted speed limit is safe for cars but not necessarily safe for large vehicles like buses.

Not quite. The answer is secured and out of the way of any exit.

Carry-on baggage must not be left in a doorway or aisle where it could trip riders. Secure baggage and freight so it (a) remains undamaged; (b) allows the driver to move freely and easily; (c) allows riders to exit by any window or door in an emergency; and (d) protects riders from injury if carry-on baggage falls or shifts.

Not quite. The answer is 500 pounds.

Buses may carry small amounts of certain hazardous materials such as small-arms ammunition and consumer commodities marked "Limited Quantity" (formerly "ORM-D"). Buses may not carry more than 100 pounds of any class or more than 500 pounds total.

Not quite. The answer is do not allow riders on the bus until departure time.

To help prevent theft or vandalism of the bus, charter bus drivers should not allow passengers to board the bus until departure time.

Not quite. The answer is You can carry any hazardous materials on your bus as long as they are properly labeled.

Most hazardous materials are prohibited on buses. However, certain hazardous materials (such as small-arms ammunition marked "Limited Quantity") may be allowed on a bus if the packages are properly labeled. Don't allow any hazardous material on your bus until you first make sure that the rules allow it.

Not quite. The answer is slow down.

When switching from high-beam lights to low beams, slow down, since you will not be able to see as far in front of you.

Not quite. The answer is scan the interior of your bus and the road all around it.

Many charter and intercity carriers have passenger comfort and safety rules. While driving, scan the interior of your bus as well as the road ahead, to the sides, and to the rear. You may have to remind riders about the rules, or remind them to keep their arms and heads inside the bus.

Not quite. The answer is it must be closed whenever the bus is in motion.

Emergency exits must be closed whenever the bus is in motion. If an emergency exit has a red emergency exit light, it should be turned on whenever conditions require you to turn on your headlights.

Not quite. The answer is regularly as part of your scan for potential hazards.

While driving, scan the interior of your bus as well as the road ahead, to the sides, and to the rear. Check your mirrors regularly. You need to make regular checks of your mirrors to be aware of traffic and to keep an eye on your vehicle. Check more often in special situations.

Not quite. The answer is Allow much more space than is needed under ideal driving conditions.

The usual formula for following distance under ideal conditions is one second for every ten feet of vehicle length, plus an extra second if you are traveling at over 40 mph. The only thing the CDL manual says about following distance on slippery roads is that you should allow "much more space to stop." The Federal Motor Carrier Safety Administration (FMCSA) recommends doubling your usual following distance under poor driving conditions.

Not quite. The answer is in a closed building with passengers on board.

Avoid fueling your bus with riders on board unless it is absolutely necessary. Never refuel in a closed building with riders on board.

Not quite. The answer is Anyone or anything that may cause an unsafe condition

A hazard is a road user or road condition that presents a possible danger. A hazard is something that can go wrong but shouldn't if you've been vigilant.

Not quite. The answer is must never be left in a doorway or aisle.

Carry-on baggage must not be left in doorways or aisles because someone could trip over it or it could block the way to an emergency exit.

Not quite. The answer is Slow to a safe speed before entering the curve, then accelerate slightly through it.

The safest way to take a curve is to slow down before the curve and then accelerate slightly through the curve. Braking in a curve risks a skid.

Not quite. The answer is Yes, but only up to 100 pounds.

Many hazardous materials cannot be carried on a bus. These include any amounts of Division 2.3 poison gases, liquid Class 6 poisons, or tear gas; or more than 100 pounds of solid Class 6 poisons. Also, buses may never carry explosives (except small-arms ammunition) or radioactive materials in the space occupied by people. Finally, buses may not carry more than a total of 500 pounds of allowed hazardous materials, and no more than 100 pounds of any one class.

Not quite. The answer is may be locked in a partially open position.

You may lock roof hatches into a partially open position to provide fresh air. However, don't leave them open all the time. When open, they add to the bus's height, which can pose problems when driving through an underpass with low vertical clearance.

Not quite. The answer is not allow the rider to do it.

Buses are allowed to carry small amounts (up to a total of 500 pounds) of certain hazardous materials. But not battery acid or gasoline.

Not quite. The answer is all of the above.

Many charter and intercity carriers have passenger comfort and safety rules. Mention these rules to your passengers at the start of the trip. While driving, scan the interior of your bus as well as the road ahead, to the sides, and to the rear. You may have to remind riders about the safety rules, or warn them to keep their arms and heads inside the bus.

Not quite. The answer is 3 seconds

The formula for following distance is one second for every ten feet of vehicle length, plus an extra second if you are traveling over 40 mph. Therefore, for a 30-foot vehicle, you should leave a following distance of at least 30/10 = 3 seconds. Add an extra second (for a total of 4 seconds) if you're traveling over 40 mph.

Not quite. The answer is Both of the above are true.

Don't tow a disabled bus with passengers aboard unless it would be unsafe to discharge them first. In that case, tow or push the bus to the nearest safe location to discharge the passengers.
