Maine CDL: Passenger Vehicles Practice Test

Not quite. The answer is don't talk with riders.

While driving, stay focused on the driving task. Keep an eye on your riders, but don't talk with them or engage in any other distracting activities.

Not quite. The answer is railroad crossings marked as "exempt"

At unattended drawbridges and ordinary railroad crossings, you must stop and look before you proceed. However, a railroad crossing marked as "exempt" or "abandoned" has been abandoned, or its use has been discontinued. At such crossings, you don't have to stop, but you must slow down and check for other vehicles before proceeding.

Not quite. The answer is service brakes.

Mass transit coaches may have a brake-door interlock system. Its purpose is to apply the service brakes and hold the throttle in idle position whenever the rear door is open, making it safer for passengers to enter or exit through the rear door. The interlock releases when you close the rear door. Note: On a bus with a brake-door interlock, opening the rear door is NOT a substitute for applying the parking brake!

Not quite. The answer is remind riders to take carry-ons with them whenever they get off the bus.

Once you've arrived at a bus stop, announce the location and bus number. If the aisle is on a lower level than the seats, remind disembarking passengers to watch their step. Also remind disembarking passengers to take all their carry-on luggage and other personal effects with them as they get off the bus.

Not quite. The answer is 500 pounds

Buses may carry small amounts of certain hazardous materials, such as small-arms ammunition labeled "Limited Quantity," emergency hospital supplies, and drugs. Buses may not carry more than 100 pounds of any hazard class or more than 500 pounds total.

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 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 depends on the state.

There is no national requirement for coach buses to stop at permanent weigh station locations. Instead, each state can set its own rules. As of March 2021, there are 24 states in which coach buses must stop at weigh stations, at least under certain circumstances.

Not quite. The answer is the AM/FM radio.

Before you start to drive, you must check all the critical systems such as steering, brakes, tires, and emergency equipment to be sure they work properly. For the passengers' safety, you must also check such interior items as seats, handholds, railings, signaling devices, and emergency exits. FM or DVD music is nice, but you can safely drive your passengers to their destinations without it.

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 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 flash your brake lights to let the drivers behind you know that you are stopping.

You may have to stop on the roadway to load or unload passengers. In such situations, warn following drivers by flashing your brake lights. Do not stop suddenly.

Not quite. The answer is 15

Under federal regulations, every bus transporting passengers must stop between 15 and 50 feet from the nearest rail at a railroad crossing.

Not quite. The answer is may be unsafe for a bus.

The posted speed for a curve may be safe for cars but too fast for buses. With good traction, the bus may roll over; with poor traction, it might slide off the curve. If your bus leans toward the outside on a banked curve, you are driving too fast. The safest way to take a curve in a bus is to slow down before the curve and then accelerate slightly through the curve.

Not quite. The answer is 50 feet

When you approach a drawbridge without a signal light or traffic control attendant, you must stop at least 50 feet before the draw of the bridge to make sure that the drawbridge is closed and safe to cross.

Not quite. The answer is The driver's seat

The driver's seat in every bus must be equipped with a seat belt in good working order. Always wear your seat belt whenever your bus is in motion. In the event of a crash, your seat belt will keep you from being badly injured or thrown out of your seat, which would result in your losing control of your vehicle.

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.

Not quite. The answer is You need about four times as much braking distance at 40 mph as at 20 mph.

When you increase your speed, your braking distance increases as the square of the speed increase. If you double your speed, your braking distance will be four times as great.

Not quite. The answer is so any door or window can be used in an emergency.

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 as a safety feature when the rear door is open.

Mass transit coaches may have a brake-door interlock system. Its purpose is to apply the brakes and keep the engine idling whenever the rear door is open. The interlock releases when you close the rear door. Note: On a bus with a brake-door interlock, opening the rear door is NOT a substitute for applying the parking brake!
