Maine CDL DMV Knowledge Test Class A 2

The best thing to do when confronted with an aggressive driver is to get out of their way, if possible. Avoid making eye contact, which could further provoke the driver. Ignore any hand gestures made by the driver.

Placards must be placed on the front, the rear, and both sides of a vehicle carrying hazardous cargo. They must be readable from any direction.

On flatbed trailers, cargo must be secured by tie-downs to keep it from shifting or falling off while the vehicle is in motion. Tie-downs may also be used to prevent cargo shifting in closed vans. Shifting cargo could affect the handling of a vehicle.

If you are asked to complete an offset back/left parking maneuver, you should first pull straight forward, then back up to the left. Your vehicle must be parked completely within the boundaries of the parking space.

It is a driver's responsibility to make sure their vehicle is not overloaded. They must be aware of legal weight limits and the maximum weight that their vehicle is rated to carry, including the weight capacity rating of the suspension system.

You should always slow down to a safe speed and shift into a lower gear before entering a curve.

If you see a crash involving an aggressive driver, you should stop a safe distance from the crash scene, wait for police to arrive, and inform them of the aggressive behavior you witnessed.

Drowsy driving is most common during the night because people are naturally prone to be less alert in the hours during which they are normally asleep. If you must drive at night, take every precaution to prevent fatigued driving.

If you are asked to complete an offset back/right parking maneuver, you should first pull straight forward, then back up to the right. Your vehicle must be parked completely within the boundaries of the parking space.

When using your turn signals, you should signal well before the turn or lane change, signal continuously throughout the turn or lane change, and cancel the signal after you have completed your move.

It is important to inspect your tires before every drive. Rust around wheel nuts may indicate that they are loose.

Texting while driving a CMV is prohibited. "Texting" is defined as manually entering text into, or reading text from, an electronic device.

On a wet road, it is possible for a vehicle's tires to lose traction with the road surface and begin to glide along on the layer of water. This is referred to as hydroplaning. Hydroplaning can occur at speeds as low as 30 mph.

If you encounter an aggressive driver, you should not let yourself be provoked by any angry gestures they make toward you. Avoid making eye contact with the other driver and do not try to race them.

In newer vehicles with air brakes, the parking brake is controlled by a yellow, diamond-shaped knob. The driver should pull the knob outward to apply the parking brakes and push the knob inward to release them.

Splitting driving responsibilities with a second driver lowers the chance that either of you will drive while fatigued. You can also reduce the risk of fatigue by avoiding heavy foods and keeping the interior of the cab cool.

If a vehicle is equipped, an application pressure gauge shows how much air pressure is being applied to the brakes. This gauge can help a driver identify if their brakes are beginning to fade.

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.

When performing a static leakage test on a double combination vehicle with air brakes, the leakage rate should be no more than 3 psi in one minute. If the air leaks from the air brake system at a quicker rate, the vehicle should not be driven because something likely needs to be repaired.

Tire load is defined as the maximum safe weight that a tire can carry at a specified pressure.

To reduce the risk of developing aggressive driving behavior, you should take measures to manage your stress. One strategy to do this is to simply take a deep breath and accept your circumstances if you realize you will be late to your destination.

If you are asked to alley dock, you should first pull past the alley and stop your vehicle in a position that is parallel to the outer boundary. From there, you should back your vehicle entirely into the alley parking area. Your vehicle should be parked in a straight position within the boundaries of the parking space.

You should not brake while making a quick turn to avoid a hazard. Doing so could cause your wheels to lock and make your vehicle skid out of control.

A dual air brake system is made up of two separate air brake systems. If there is an air leak in one system, it may not affect the other.

When pressing the brake pedal in a vehicle with S-cam brakes, air will enter the brake chambers. The added air pressure will push out the rods and move slack adjusters, twisting the brake camshafts.

When performing a static leakage test on a triple combination vehicle with air brakes, the leakage rate should be no more than 5 psi in one minute. If the air leaks from the air brake system at a quicker rate, the vehicle should not be driven because something likely needs to be repaired.

If you find yourself being tailgated by another driver, you should increase your following distance and avoid making quick moves. Increasing your speed may only result in the other driver continuing to tailgate you at a higher speed. Do not turn on your taillights or flash your brake lights at the other driver.

When stopped on the side of the road, be sure to turn on your vehicle's four-way emergency flashers, especially during times of lowered visibility. Place warning devices within 10 minutes of being stopped.

If an emergency vehicle using its flashing lights is stopped on the side of a multilane road, move over laws require drivers to vacate the lane directly next to the vehicle, if possible. If a driver cannot move over safely, they must slow down and proceed with caution.

All commercial motor vehicles are required to be equipped with the proper emergency equipment. This may include 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 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.

When inspecting a vehicle's suspension, you should look for broken or missing leaves in the leaf springs. Any defect of this kind is dangerous. If one-fourth or more of the leaves are missing from any leaf spring, the vehicle must be put out-of-service.

Truck tractors with air brakes built on or after March 1, 1997, and other vehicles with air brakes built on or after March 1, 1998, must be equipped with anti-lock brakes.

A pre-trip vehicle inspection should be done in the same way every time. Consistency will help a driver learn all of the proper steps and decrease the possibility of the driver forgetting to inspect something.

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