Vermont CDL DMV Endorsement Double 2

You should never assume that you will hear an approaching train. The train operator may fail to sound the horn, or the use of a train's horn may be prohibited in a specific area. Even if the train does sound its horn, noise from inside your own vehicle may prevent you from hearing the train until it is dangerously close.

It is best to avoid driving through large puddles or moving water. If there is no way to avoid driving through water, you should slow down, shift into a low gear, and gently apply the brakes. Pressing linings against the brake drums or discs will keep water, mud, silt, and sand from getting inside the brake mechanisms.

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.

When approaching a long downgrade, you should shift into a lower gear then use proper braking techniques. Using the brakes alone could cause them to overheat and fail. The braking power of the engine, which is maximized by being in a lower gear, will be the principal way of controlling your speed on a downgrade.

If the low pressure warning signal activates while you are driving, it is important that you safely exit the roadway as soon as possible and park your vehicle. If the air pressure gets too low, the brakes will no longer work well enough for you to stop safely.

For safe driving, it is essential that you maintain cushions of space on all sides of your vehicle. This helps to ensure that you will have time to take appropriate action if a problem arises.

Incorrect coupling and uncoupling of combination vehicles can have extremely dangerous consequences.

When doing a pre-trip inspection on a vehicle with power steering, be sure to check the hoses, pumps, and fluid level. In particular, you should check the hoses for leaks.

If you encounter a driver who seems distracted on the road, you should give them plenty of room and maintain a safe following distance.

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.

You should always slow down and shift into a lower gear before starting down a hill. If you do not begin to drive down a hill at a low enough speed, you risk overusing your brakes, causing them to overheat and fade.

A vehicle that is equipped with air brakes must also be equipped with a supply pressure gauge. This gauge tells the driver how much air pressure is in each of the vehicle's air tanks.

Texting while driving is particularly dangerous because it is both a mental and physical distraction to the driver. In addition to diverting a driver's mental attention away from the road, texting requires a person to remove at least one hand from the vehicle's controls.

It is essential that your low pressure warning light functions properly. After allowing the system to charge, you can test the warning signal by rapidly applying and releasing the brake pedal. This will release air from the braking system and the warning signal should come on when pressure drops to a dangerous level.

When driving a vehicle with ABS, you should brake in the same manner as you would in a vehicle without ABS.

When inspecting a vehicle equipped with power steering, you should inspect the hoses, pumps, and fluid levels. Specifically check the hoses for leaks.

Check hydraulic brakes by pumping the brake pedal three times before applying firm pressure to the pedal for five seconds. The pedal should not move. If it does, there may be a leak or some other problem in the braking system.

A trailer may swing out and strike other vehicles if its wheels lock up. This is especially likely with lightly-loaded trailers.

Pressing and releasing the brake pedal unnecessarily can let air out of the braking system faster than the compressor can replace it. Air brakes may cease to work effectively if the pressure becomes too low.

B:C fire extinguishers are designed to work on electrical fires and burning liquids. Don't pour water on an electrical fire.
