Mississippi CDL DMV Knowledge Test Class A 2

When approaching your vehicle before an inspection, make note of its general condition and ensure that it is not damaged or leaning. Look under the vehicle for fresh leaks of oil, grease, or fuel. Check around the vehicle for hazards to movement, such as people, other vehicles, or low-hanging wires or tree limbs.

Over-length, over-width, and/or overweight loads may require special permits from the Department of Transportation.

When doing a pre-trip inspection during the winter, you should pay extra attention to the coolant level and amount of antifreeze; the defrosting and heating equipment; the wiper blades and windshield washer; the tires and tire chains; the lights and reflectors; the windows and mirrors; the hand holds, steps, and deck plates; the radiator shuttles and winterfront; and exhaust system.

Because live animals can lean during curves, and otherwise move in transit, the weight distribution of a cargo of livestock is unstable. Driving with livestock requires special care.

It is important for you to be aware of your surroundings at all times. To do this, regularly check your mirrors.

A dual air brake system is made up of two separate air brake systems. The systems share a single set of brake controls, but each has its own air tanks, hoses, and lines. One system typically operates the regular brakes on the rear axle or axles while the other system operates the regular brakes on the front axle.

If you are twice convicted of violating any state law regarding hand-held mobile phone use, your CDL will be disqualified. Consequences will become more severe with subsequent violations.

Regrooved, recapped, or retreaded tires are prohibited on the front wheels of a bus.

Driving while fatigued is dangerous. Warning signs of fatigue include difficulty focusing; repeated yawning or rubbing of the eyes; daydreaming or wandering thoughts; and drifting out of your lane.

Bridges will generally freeze before other parts of the roadway. Be careful on bridges when temperatures are around the freezing point.

After a tire has been changed, the driver should stop a short distance later to recheck the tightness of the tire's lug nuts.

When checking your tires as part of a pre-trip inspection, it is important to verify that the tire pressure is neither too low nor too high.

The added weight of a heavy load will make a vehicle sit lower than usual. A vehicle will often be taller when carrying a light load than when carrying a heavy load. If your vehicle fits under an overpass while carrying a full load, it is not guaranteed that it will fit under the same overpass if it is empty.

Before starting down a hill, you should shift into a lower gear. This will help get your vehicle to a speed that you can control without having to use your brakes too much.

If you must drive in reverse, you should first walk around your vehicle to look at the path of travel and check for obstacles. Because mirrors have blind spots, you cannot rely exclusively on them. It is recommended to use a helper whenever possible.

If there is a fire in your vehicle, the first thing you need to do is leave the road and stop. Park in an open area away from anything that could catch fire, such as plants or other vehicles. Do not pull into a service station.

If you begin to feel tired while driving, the only safe action to take is to stop and get some sleep. Trying to fight the fatigue and press on is very dangerous and can result in a fatal crash. You should not rely on artificial stimulants; these may help keep you awake a while longer, but they won't make you more alert.

All U.S. states share information about CDL and CLP licenses in a computerized database. If you apply for a license in one state, a state will check this database to verify that you do not already have one such license in another state.

At times when visibility is low, you should turn your headlights on to the low beam setting. If you are having a difficult time seeing others, they are probably having a difficult time seeing you.

Fatigue and lack of alertness are major hazards when driving at night. Most people are the least alert at night, especially after midnight.

As long as the brakes are properly maintained, using air brakes is a safe and effective method of stopping large, heavy vehicles.

Anti-lock brakes on only a single axle still provides a driver with more control while braking than they would have without any anti-lock brakes.

Always change lanes slowly and smoothly to maintain control of your vehicle. Doing this will also allow a driver that you did not see time to move out of the way of your vehicle. Use the proper turn signal to communicate with other road users.

If you must back up, it is safest to back toward the driver's side of the vehicle. This way, as the driver, you will have the best possible view of your path of travel.

To obtain a hazardous materials endorsement, you will be required to submit your fingerprints and undergo a TSA background check.

In an air brake system, the air compressor governor controls when the air compressor pumps air into the air storage tanks.

When checking the oil pressure gauge as part of a vehicle inspection test, you must ensure that it is working. The gauge should show increasing or normal oil pressure, or the oil pressure warning light should turn off. If equipped with one, the oil temperature gauge should begin a gradual rise to the normal operating range.

If you encounter an aggressive driver, the most important thing to do is get out of their way, if possible. Do not provoke the driver by challenging them or making eye contact, and do not let yourself be provoked by rude gestures they might make.

Always signal your intentions before turning or changing lanes. Do not assume that other drivers will move out of your way simply because you are signaling to turn.

Areas with heavy traffic, road construction, large numbers of pedestrians, or severe weather demand extra attention from a driver. The driver should avoid all possible distractions while in such areas, including cell phone use.

When performing a static leakage test on a single vehicle with air brakes, the leakage rate should be no more than 2 psi in a minute. If air leaks from the air brake system at a quicker rate, the vehicle should not be driven because something likely needs to be repaired.

To keep an engine fire from spreading, you should turn off the vehicle's engine as soon as possible. Do not open the hood if you don't have to.

In newer vehicles with air brakes, the parking brakes are controlled by a diamond-shaped yellow knob. Pull the knob out to activate the parking brakes and push it in to release them.

Tar in road pavement often rises to the surface of the road, or "bleeds," in very hot weather. Watch for such areas because they can be very slippery.

Parking brakes should be used whenever you park. If necessary, chock your wheels.
