Oklahoma CDL: Passenger Vehicles Practice Test

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 in front of the standee line.

Buses that allow passengers to stand must have some way to show passengers that they must stand behind the driver. This can be a two-inch-wide line (called the standee line) on the floor behind the driver's seat.

Not quite. The answer is it must be secured while the bus is being driven.

Emergency exit doors and windows must be securely closed whenever the bus is moving. Signage must be visible. If there is a red emergency door light above the emergency exit, it must work properly and be turned on whenever you use your headlights.

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 If you turn on your headlights, you don't need to turn on the red emergency door light.

If an emergency door has a red emergency exit light, it must work properly. However, you only need to turn it on when visibility is poor enough that you have switched on your headlights (such as at night or in poor weather).

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 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 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 on any wheels except the front wheels.

Federal regulations prohibit the use of recapped, regrooved, or retreaded tires on the front wheels. A tire failure on the steering axle is more likely to result in loss of control than a tire failure elsewhere.

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 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 after completing the lane change.

You must start signaling before changing lanes and cancel the turn signal when the lane change is complete.

Not quite. The answer is Fire extinguisher and warning devices for stopped vehicles

Federal regulations require every commercial motor vehicle (CMV) to carry one of the following warning devices in case the driver must stop the CMV on the road: three reflective triangles or six fusees. Federal regulations also require every CMV to carry a fire extinguisher. Your state may also require extra emergency equipment, such as a first-aid kit, on certain vehicles.

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 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 all of the above have been checked.

Before driving your passenger vehicle, you must also inspect the interior to ensure passenger safety. Make sure that the aisles and stairwells are clear, all emergency exits are closed and secured, all signaling devices are in working order, and the handles, handholds, and railings are securely fastened.

Not quite. The answer is You should avoid traveling alongside other vehicles whenever possible.

Whenever another vehicle is traveling alongside yours, there's always a chance that the vehicle might try to move into your lane and accidentally hit your vehicle. Also, the vehicle is blocking you from changing lanes. It's safer to find an open spot where there are no vehicles on either side of you. (Of course, that may not be possible in heavy, congested traffic.)

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 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 only if getting off the bus would be more risky for the riders.

Passengers should not be aboard a bus while it is being towed unless it would be more dangerous for them to exit the vehicle. Passengers can remain aboard the bus only until it is towed or pushed to the nearest safe location.
