Connecticut CDL DMV Knowledge Test Class A 2

Wheels and rims with welding repairs are not safe to be used. Replace any damaged wheels and rims.

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.

Be sure to check your mirrors before beginning a drive. Your posture may change day to day and your mirrors may need to be adjusted.

The first hazardous materials class includes explosives such as ammunition, dynamite, and fireworks.

On a vehicle with air brakes, pressing and releasing the brake pedal unnecessarily may let air out of the braking system faster than the compressor can replace it. This may cause the system's air pressure to become too low and the brakes to stop working.

When inspecting your vehicle's engine, check the belts for tightness and excessive wear. The amount of "give" that is safe for each belt in a given engine will vary, so learn what is appropriate for your vehicle.

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.

At speeds below 40 mph, you should allow at least one second of following distance for every 10 feet of your vehicle. Follow the same formula when traveling at faster speeds, then add one additional second to your following distance. Remember that larger vehicles require more space to stop than smaller vehicles.

If the low air pressure warning signal comes on while you are operating a vehicle with air brakes, you should stop and safely park the vehicle as soon as possible. It is essential that you are able to stop safely while you still have some braking power remaining.

Distractions while driving can be physical (such as reaching for an object), mental (such as making conversation with a passenger), or both (such as holding a phone to send texts). Strategies to help you avoid distracted driving include pre-programming radio stations; planning out your route in advance; avoiding complex or emotionally taxing conversation while driving; adjusting your mirrors before setting out; and not eating, drinking, or smoking while behind the wheel.

The height of a vehicle's center of gravity is very important to a driver's ability to safely handle the vehicle. Always distribute the weight of cargo as low as possible.

There are two indicators that determine when you need to shift into a higher gear. One indicator is the engine speed (rpm). You should read your vehicle's manual to learn its rpm range and shift up when you reach the top of that range. The other indicator is road speed (mph). You should learn which speeds each gear can accommodate, then keep an eye on the speedometer and shift up as needed.

When braking a vehicle equipped with an Anti-Lock Braking System (ABS), you should not brake any differently than you would if driving a vehicle with a different braking system.

When exiting 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 vehicle control skills test.

Blocking may be used on all sides of a piece of cargo to keep it from sliding while the vehicle is in motion.

Distractions while driving can be physical (such as reaching for an object), mental (such as making conversation with a passenger), or both (such as holding a phone to send texts).

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.

It is important to know the maximum air loss rate that is safe for your specific vehicle. A double combination vehicle should have a leakage rate no higher than 4 psi in a minute during an applied leakage test.

While it is best to entirely avoid driving in fog, you should turn on your low beam headlights if you must drive in foggy conditions. Using high beams is a bad idea because the lights will reflect off of the fog and back into your eyes, making the road and its surroundings even more difficult to see.

Escape ramps are constructed in areas with steep downgrades to allow a means of safely stopping runaway vehicles. They consist of a long bed of loose, soft material, and sometimes an uphill slope.

When turning on your vehicle's engine, the lights on the dash should come on and then turn off. If the ABS malfunction light stays on, the system is not working properly. In the case of a truck with a trailer, if the yellow light on the left rear of the trailer stays on once the engine has been started, the system is not working properly.

Alcohol consumption impairs muscle coordination, reaction time, depth perception, vision, judgement, and inhibition. For some people, signs of impairment may begin with the first drink of alcohol. It is safest to not operate any motor vehicle after consuming alcohol in any amount.

While regular mirror checks should be part of your normal driving routine, checking your mirrors is especially important when turning, changing lanes, merging, and performing tight maneuvers.

For safety, you must wear your seat belt at all times while operating a CMV.

In an air brake system, the application pressure gauge shows how much air pressure is being applied to the brakes. Not all vehicles with an air brake system have this gauge.

You must tell your employer within 30 days if you are convicted of any traffic violation, aside from a parking violation, no matter which vehicle you were driving at the time of the violation. If your license is suspended, revoked, or canceled, or if you are otherwise disqualified from driving, you must tell your employer within two business days.

Cargo on a flatbed trailer should be secured by at least one tie-down for every 10 feet of the cargo's length. Cargo should be secured by a minimum of two tie-downs, regardless of size.

After the engine is started, the warning lights and buzzers should deactivate immediately. The charging circuit warning, oil, coolant, and Anti-Lock Braking System (ABS) lights should all turn off.

If confronted by an aggressive driver, it is most important to get out of their way. Avoid making eye contact and do not gesture at them. Report them to the appropriate authorities once you can safely do so.

Hydroplaning occurs on surfaces where water has collected. If there is enough water, vehicles can hydroplane at speeds as low as 30 mph. Hydroplaning becomes more likely if tires are under-inflated or if the tread is worn.

Retarders help to slow vehicles, reducing drivers' need to use brakes.

If you must come to a stop before making a turn during the driving skills test, you should come to a smooth stop behind any stop line, crosswalk, or stop sign. Keep your front wheels aimed straight ahead and do not let your vehicle roll. If stopping behind another vehicle, stop where you are still able to see the rear tires of the vehicle ahead of you.

An Individual Vehicle Distance Record (IVDR) must include information about the distance traveled by a vehicle and the amount of fuel purchased. The required distance information includes the dates of a trip and the total distance traveled by the vehicle.

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. You should be very careful when temperatures are below freezing and the road looks wet.

During a trip, you should regularly check the gauge and instrument panels, mirrors, tires, cargo, and lights for signs of trouble.
