Kentucky CDL: Passenger Vehicles Practice Test

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 5

To determine the following distance for your vehicle, add 1 second for every 10 feet of vehicle length at speeds under 40 mph. Above 40 mph use the same formula, then add 1 second for the additional speed.

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.)

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 The driver must engage in a conversation with the riders while driving.

Avoid fueling your bus with riders on board unless it is absolutely necessary. Never refuel in a closed building with riders on board. Don’t talk with riders, or engage in any other distracting activity, while driving.

Not quite. The answer is Swaying your body to see around obstructions

A vehicle's pillars help hold up the roof and maintain structural integrity of the vehicle. The pillars on a bus can be quite wide. Together with the side mirrors, they create obstructions to your vision that can be at least a foot wide, resulting in blind spots. A pedestrian (or even a small vehicle) can seem to disappear completely behind a pillar, which can be especially dangerous if you turn into the pedestrian's path. For this reason, your bus driving instructor may teach you to "rock and roll" when turning your bus: sway your body forward and backward and from side to side to help you see around the pillars and mirrors.

Not quite. The answer is Never

Never drive with an open emergency exit door or window. Keep it closed for your passengers' safety.

Not quite. The answer is No, because it may distract the bus driver from driving.

Conversations with passengers represent a distraction from the driving task. The bus driver should avoid all potential distractions while driving the bus. The only real way to treat feelings of sleepiness is with sleep.

Not quite. The answer is 6 fusees

Make sure your bus has the fire extinguisher and emergency reflectors (3 reflective triangles or at least 6 fusees) required by law. Spare electrical fuses and liquid-burning flares are no longer required as emergency equipment under current FMCSA regulations.

Not quite. The answer is 50 feet

Stop at drawbridges that do not have a signal light or traffic control attendant. Stop at least 50 feet before the draw of the bridge and look to make sure the draw is completely closed before you proceed across.

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],

Not quite. The answer is (b) and (c)

When bus passengers are injured, it’s usually because the driver (a) opened or closed the doors too quickly, (b) started or stopped too quickly or abruptly, (c) turned too quickly or abruptly, or (d) failed to check on passengers often enough while driving.

Not quite. The answer is small-arms ammunition.

Buses may carry small-arms ammunition marked "Limited Quantity" (relatively small quantity of hazmat; formerly "ORM-D"), emergency hospital supplies, and drugs. Buses may carry small amounts of some other hazardous materials if the shipper cannot send them any other way. Buses may not carry more than 100 pounds of any class or more than 500 pounds total.

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 No, not in space occupied by people.

Passenger buses can carry up to 100 pounds of each class of hazardous materials and up to 500 pounds total. However, there are some exceptions. Division 2.3 (poison gas) and liquid Class 6 (poison) cannot be carried in any amounts. Explosives and radioactives cannot be carried in the passenger area. Riders sometimes board a bus with an unlabeled hazardous material. Do not allow riders to carry on common hazards such as car batteries or gasoline.

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 do any of the above.

If you have a drunk or disruptive passenger, you have a few options for the safety of all concerned. If possible, follow your carrier's guidelines for dealing with such passengers. Otherwise, you may drop the passenger off at the next scheduled stop or in any clean, well-lighted place where there are many people.

Not quite. The answer is you will have time to plan your escape if the hazard becomes an emergency.

A hazard is not an emergency – but it can become one. Always scan the road ahead, looking for common types of hazards such as work zones, emergency vehicles parked on the side of the road, and foreign objects lying on the road. The sooner you spot a hazard, the more time you will have to plan how to deal with it before it becomes an actual emergency.

Not quite. The answer is safe for cars in good weather.

Each curve has a safe "design speed," which is its safe speed for cars in good weather. However, at that speed, a bus is more prone to rolling over. And it may not be safe for any vehicles to travel at that speed in bad weather. In particular, a bus could go sliding right off the road. For safety on curves, slow down below the posted speed. If your bus is leaning outward on a banked curve, you are driving too fast.
