Washington CDL: Passenger Vehicles Practice Test

Not quite. The answer is at intersections.

Bus accidents often happen at intersections, where there are many drivers and pedestrians doing different things. Use caution at intersections even if there are signs or signals that are supposed to control traffic. Also use caution at railroad crossings. Buses are required to stop at railroad crossings.

Not quite. The answer is 5 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 40-foot vehicle traveling at 50 mph, you should leave a following distance of 40/10 + 1 = 5 seconds.

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 All of the above

Buses may carry small amounts of certain hazardous materials, such as small-arms ammunition labeled "Limited Quantity" (formerly "ORM-D"), emergency hospital supplies, and drugs. Under the Americans with Disabilities Act, federal regulation 49 CFR 37.167 allows a passenger with a disability to bring portable oxygen equipment on board for medical use. Extra medical oxygen cylinders can be stowed in a baggage compartment, if they are designed for personal use.

Not quite. The answer is The emergency window

Emergency exit windows and doors must be closed while the bus is being driven.

Not quite. The answer is wait for a sufficient gap.

You should know the size of the gap that your bus needs to accelerate and merge with traffic. Before leaving the bus stop, wait for a large enough gap to open. Never assume other drivers will brake to give you room when you signal or start to pull out.

Not quite. The answer is in the aisles.

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. Carry-on luggage must be stowed so it can't restrict the driver's movements or injure passengers if it falls or shifts.

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 every emergency exit

As part of your vehicle inspection test, you will have to check every emergency exit to be sure that it is undamaged, operating smoothly, and able to be closed securely from both the inside and the outside. Demonstrate one emergency exit and explain how various exits operate. Also check that all emergency exit warning devices are working.

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 All of the above

When arriving at the destination or intermediate stops, announce in a clear voice: the location, the reason for stopping, the next departure time, and the bus number.

Not quite. The answer is All of the above

When changing lanes, check your mirrors at each of the following times: (1) before you change lanes, to make sure there is enough room; (2) after you have signaled, to check that no one has moved into your blind spot; (3) right after you start the lane change, to double-check that your path is clear; and (4) after you complete the lane change.

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 your ability to drive safely is impaired by illness or fatigue.

Federal regulations prohibit you from operating a commercial motor vehicle if your ability to drive safely is impaired for any reason: fatigue, illness, or the side effects of medications you're taking.

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 Behind the driver's seat

Some buses are designed to allow passengers to stand. These buses must have a means of showing passengers that they cannot stand forward of the driver's seat. One way is to have a standee line, a two-inch-wide line on the floor just behind the driver's seat.

Not quite. The answer is Zero

Federal regulations require all seats to be securely fastened to the bus. Temporary folding seats are not permitted on a bus unless it's carrying agricultural workers on short trips. [49 CFR 393.91],

Source: 29 CFR 500.105

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 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 15 to 50 feet

At a railroad crossing, you must stop between 15 and 50 feet from the nearest rail. Don't proceed across until you are sure that no trains are coming. (Don't trust the railroad crossing signals alone; signals can malfunction.)
