Virginia CDL DMV Knowledge Test Class A 2

Most states have an Implied Consent Law, which means that by driving a vehicle on the state's roads, you have agreed to undergo a drug or alcohol test if a police officer asks you to do so. If you refuse to submit to a test, you will lose your operating privileges. Make sure you are aware of the laws for every state in which you drive.

When making mirror checks, you should look at the mirrors fairly quickly. If you spend too much time looking in a mirror, you may travel a substantial distance down the road without seeing what is coming up ahead.

It is important to check your mirrors regularly when driving, both to be aware of other traffic and to observe problems that may arise on your own vehicle.

When stopping, you should push the brake pedal down gradually. Braking gradually will help you to maintain proper control of your vehicle.

Texting while driving is more distracting than talking on a phone because it involves both mental and physical distraction. It takes mental focus away from driving, requires you to take one or both hands off of the steering wheel to enter text, and forces you to take your eyes off the road to look at your phone screen.

If you must stop on the side of the road, make sure to use your four-way emergency flashers. This is particularly important at night.

Cargo should be inspected before beginning a trip, within the first 50 miles of the trip, and every three hours or 150 miles traveled thereafter. The driver of a truck transporting cargo is responsible for the cargo being safely secured throughout the trip.

Always watch for hazards on the road ahead. Doing this will allow you time to react to hazards before meeting them.

If you are convicted of any kind of traffic violation in any type of vehicle, you must notify your employer within 30 days of the incident. You must also inform your motor vehicle licensing agency within 30 days if the incident happened in another jurisdiction. This rule does not apply to parking infractions.

The low air pressure warning signal must activate before the air supply pressure drops below 55 psi in the air tank. If the warning signal does not turn on when being tested during an inspection, the vehicle is not safe to drive.

A vehicle inspection should be completed in the same order every time. This will make it easier for you to learn all of the steps and will make it less likely that you will forget to check something.

Explosives are placed in hazardous materials Class 1.

If you experience tire failure, you may hear the loud "bang" sound of a blowout or feel a heavy thumping or vibration in your vehicle. If steering begins to feel heavy, or if the rear of your vehicle begins to fishtail, you should stop to check your tires.

Look at your truck's gauges when starting the engine. The oil pressure in an engine should come up to a normal level within seconds of the vehicle's engine being started.

Backing is always dangerous because it is impossible to see everything that is behind your vehicle. Only drive in reverse if it is absolutely necessary.

Controlled braking is the method of applying a vehicle's brakes as hard as possible without locking the wheels. A driver should keep steering wheel movements very small if braking while using this method.

If you are not certain that your vehicle will fit under overhead objects, you should slow down and take a different route, if possible.

A common cause of vehicle fires in the aftermath of an accident is the improper use of flares near spilled fuel. Use flares with caution.

During a pre-trip inspection, you should check for emergency equipment, including spare electrical fuses; three red reflective triangles, six fuses, or three liquid burning flares; and at least one properly charged and rated fire extinguisher.

A vehicle inspection should be completed in the same order every time. This will make it easier for you to learn all of the steps and will make it less likely that you will forget to check something.

Friction inside a brake drum is caused when the brake shoes and linings push against the inside of the drum. The friction in the drums will slow and stop the vehicle.

Your vehicle's horn is a tool to warn others of your presence. Because the horn may create danger by startling other drivers, you should use it only if necessary.

During the pre-trip vehicle inspection test, you will be asked to indicate where the power steering fluid dipstick or reservoir sight glass is located. You will need to show that the power steering fluid is within a safe operating range.

If you have an Anti-Lock Braking System (ABS) equipped on only the tractor, only the trailer, or only one axle, you will still have more control over the vehicle when braking than you would without ABS. You should brake normally.

During the pre-trip vehicle inspection test, you will be asked to check the power steering, water pump, alternator, and air compressor belts, if the vehicle is equipped.

The faster you are driving, the longer your stopping distance will become. Brake accordingly.

As you exit your vehicle during the basic vehicle control skills test, you must face the vehicle and maintain three points of contact at all times. If your testing vehicle is a bus, you must maintain contact with the handrail. Exiting the vehicle incorrectly may result in automatic failure of the basic control skills test.

Maneuvers that may be included in the basic vehicle control skills test include straight line backing, offset back/right parking, offset back/left parking, driver side parallel parking, conventional parallel parking, and alley docking.

Black ice is a thin layer of ice that is clear enough for the road surface to be seen through it. A road covered in black ice may look like it is merely wet instead of icy. Always be on the lookout for black ice if a road surface looks wet and temperatures are around the freezing mark.

Whenever you pass another driver, bicyclist, or pedestrian, you should assume as a precaution that they do not see you.

If you must stop on the side of the road, you must place the appropriate emergency warning devices within 10 minutes of stopping.

Always signal before turning or changing lanes to ensure that other drivers are aware of your intentions.

It is essential that exhaust system parts are not leaking or otherwise broken. A faulty exhaust system can let poisonous fumes into the cab or sleeper berth.

When checking your vehicle's pedals during a pre-trip inspection, you should ensure that there is nothing under or around the pedals that will obstruct their use. Make sure the pedals are in proper working condition and that the surfaces of the pedals are grooved, if applicable.

If used and maintained properly, air brakes are a safe and effective way to stop large, heavy vehicles.
