Utah CDL DMV Endorsement Passenger 1

If a pre-trip inspection reveals anything unsafe about your vehicle, you must get it repaired. It is illegal to operate an unsafe vehicle.

In some emergencies, the best strategy for avoiding a hazard may be to drive onto the shoulder. Most shoulders are strong enough to support the weight of a large vehicle.

When using a fire extinguisher, you should stay as far away from the flames as possible and aim at the base of the fire.

On a steep downgrade, you must use the engine's braking effect as your primary method of speed control. Be sure to decelerate and downshift appropriately before beginning to drive down the hill.

A bus should not be refueled while passengers are on board unless it is absolutely necessary to do so. In particular, a bus with riders on board should never be refueled inside an enclosed building.

Truck tractors with air brakes built on or after March 1, 1997 must be equipped with an Anti-Lock Braking System (ABS).

Your vehicle pulling to one side or the other while you are braking can indicate trouble with the brakes.

The suspension system holds up a vehicle and its load while keeping the axles in place. Faults in a vehicle's suspension system are extremely dangerous.

It is illegal to operate a CMV with a blood alcohol concentration (BAC) of 0.04 percent or more. Operating a CMV while under the influence of alcohol will result in license disqualification.

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.

After starting a vehicle's engine, the warning lights and buzzers for oil, coolant, charging circuits, and the Anti-Lock Braking System (ABS) should go out right away.

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.

Always observe posted speed limits for work zones. Slow down if road or weather conditions are adverse, and slow down even more if workers are on or near the road.

After finishing a day of driving, you may have to complete a written report on the condition of your vehicle. Be sure to mention anything that could affect safety or lead to mechanical breakdown.

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.

The three main factors that determine a person's blood alcohol concentration (BAC) are how much alcohol was consumed; how fast it was consumed; and the person's body weight. The only thing that can lower a person's BAC is waiting for the alcohol to leave their system naturally.

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.

The suspension system holds up a vehicle and its load while keeping the axles in place. Defects in this system are extremely dangerous.

If you stay in neutral for too long while double clutching and have difficulty switching your vehicle into the next gear, don't force it. Return to neutral, release the clutch, increase the engine speed to match road speed, and try again.

If you must drive so slowly that you will impede the flow of traffic, you should turn on your four-way flashers to alert drivers behind you (as long as local laws allow the use of flashers).
