Connecticut CDL DMV Knowledge Test Class A 1

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 air leaks from the air brake system at a quicker rate, the vehicle should not be driven because something likely needs to be repaired.

It is prohibited for any person to possess more than one driver license. All states share drivers' information in a computer database to help prevent issuance of licenses to drivers who already have them.

If another vehicle pulls out in front of you, it is appropriate to brake as long as there is room for your vehicle to stop while you are using the appropriate braking technique. However, if you do not have room to stop, swerving may be a safer response.

You should be cautious when you are near people who are not paying attention to the road. Be wary of drivers who are engaged in conversation with passengers, children near the road, and road workers.

Dry bulk tanks require special care to be driven, both because they have high centers of gravity and because the weight of the load can shift in transit.

Cargo with a high center of gravity makes a vehicle more likely to tip over than cargo with a low center of gravity. For this reason, it is important that the weight of cargo be distributed as low as possible.

Traffic violations classified as "serious" include excessive speeding, reckless driving, operating a CMV without a valid CDL, following other vehicles too closely, and improper lane usage. Consequences for multiple serious traffic violations can result in license disqualification.

To avoid being blinded by the lights of an oncoming vehicle at night, you can glance to the right edge of the road until the vehicle has passed.

During the on-road driving test, do not stop, change gears, pass another vehicle, or change lanes while any part of your vehicle is in a railroad crossing.

Tractors, trucks, and buses with Anti-Lock Braking Systems (ABS) have yellow malfunction lamps located on their instrument panels. Trailers have yellow ABS malfunction lamps on their left side, either on the front or rear corner.

When examining your tires during the vehicle inspection test, you should ensure that treads are evenly worn.

If your brakes fail on a downgrade, your best option is to use an escape ramp. If no escape ramp is available, it is a good idea to look for a different escape route, such as a side road or open field.

You should cover your cargo to protect people from the cargo if it spills, as well as to protect the cargo from the weather.

An operator should drive with care when transporting a cargo of hanging meat. Such a load is unstable, both because it has a high center of gravity and because the swinging of the meat can affect the driver's handling of the vehicle.

You should always complete an after-trip inspection of your vehicle at the end of a trip, day, or tour of duty. Complete a vehicle inspection report, if required.

Gross Vehicle Weight (GVW) is defined as the total weight of a single vehicle in addition to its load.

As a part of earning your CDL, you will have to pass an inspection test and demonstrate that your vehicle is safe for operation. During the vehicle inspection test, you will have to walk around the vehicle and point to or touch each item and explain to the examiner what you are checking and why. You will not have to crawl under the hood or under the vehicle.

You should be cautious when you are near people who are not paying attention to the road. Be wary of drivers who are engaged in conversation with passengers, children near the road, and road workers.

ABS is equipped in addition to a vehicle's normal braking system and it neither increases nor decreases the vehicle's braking capability. ABS activates during hard applications of the brake pedal in order to prevent wheels from locking up.

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.

The securement of cargo must be checked before beginning a trip, within the first 50 miles of a trip, and then again every three hours or 150 miles.

A driver uses a look when they open their door, leave their seated position, and walk to the back of the vehicle to check its position. During the straight line backing exercise, a driver may not exceed one look. During any other exercise, a driver may not exceed two looks.

The method of controlled braking involves applying the brakes as hard as you can without locking the wheels. If you need to make large steering adjustments while using controlled braking, you should remove your foot from the brake pedal, steer, then reapply the brakes.

Special equipment, such as warning flags or flashing lights, may be required if you are transporting an over-length load. When transporting such a a load, you will need to acquire the necessary permits. Driving is often limited to certain times.

A passive railroad crossing is a crossing that lacks control devices, like gates or warning lights. Before crossing a passive railroad crossing, you should search the tracks for approaching trains coming from either direction.

Cargo on flatbed trailers or trailers without sides must be tied down to prevent it from shifting or falling in transit.

Cargo and its securing devices must be inspected before starting a trip. After beginning a trip, the driver should check the load and securing devices within the first 50 miles on the road, every three hours or 150 miles traveled, and after every break.

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.

Compressed air in an air brake system usually contains a certain amount of water and compressor oil. The water and oil can damage the brakes if left to accumulate in the system. Manually operated air tank drains must be opened daily to remove this build-up.

In the event of an engine fire, turn off the engine as soon as possible. Do not open the hood if you can avoid doing so.

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.

To correct a drive-wheel braking skid, you should first remove your foot from the brake pedal to allow the locked wheels to begin rolling again. Quickly steer in the direction you want to go, then countersteer to prevent your vehicle from skidding in the opposite direction.

Overuse of the brakes may cause them to overheat, making them less effective. This is known as "fade."

Your vehicle's engine may need to be running in order for you to check the level of its automatic transmission fluid.

Air expands as it gets warmer, so the air pressure in your tires could reach dangerously high levels while being used in very hot weather. If this happens, stop and let your tires cool. Do not let air out of the tires, as this could result in the pressure dropping to an unsafe level once the tires cool down.
