Utah CDL DMV Knowledge Test Class B 2

Aggressive driving is the act of operating a motor vehicle in a selfish, bold, or pushy manner and without regard for the rights or safety of other road users.

When inspecting a vehicle, you should check for required emergency equipment, including at least one fire extinguisher.

A vehicle inspection report allows a driver to inform the motor carrier of issues that could affect the safe operation of a vehicle. If required, the driver should fill out a vehicle inspection report after every day of driving. They should make note of any issues that could affect the safety of the vehicle or that could lead to a mechanical breakdown.

Hydroplaning is an effect in which a vehicle's tires lose traction with the surface of the road and instead glide along a layer of water. There does not have to be a large amount of water on the road for this to occur. Hydroplaning can begin at speeds as low as 30 mph.

Cargo covers should not flap in the wind. A flapping cover could tear loose entirely, exposing the cargo, and potentially blocking your view or the view of other drivers.

To avoid becoming fatigued on a long trip, you should take a break after every 100 miles or two hours of driving. Driving through the night, or during any other time when you would normally be asleep, raises the danger of fatigue.

Backing a truck is always dangerous because the driver may not be able to see everything behind them. CMV operators should avoid backing whenever possible.

The faster you are driving, the longer your stopping distance will become. Brake accordingly.

Cargo needs to be secured appropriately to prevent it from moving in transit. Cargo should be arranged to keep the vehicle's center of gravity low and well-distributed.

If you are convicted of any traffic violations while driving any vehicle, you must notify your employer within 30 days of the conviction. This rule excludes parking violations.

Roads are particularly slippery when it first begins to rain. The water mixes with oil drippings on the road that have not yet washed away, creating a slippery and dangerous mixture.

The parking brake in a vehicle with air brakes should be used every time the vehicle is parked.

A broken exhaust system is extremely dangerous because it may introduce toxic fumes into the cab or sleeper berth.

Most heavy-duty vehicles use dual air brake systems. A dual system has two separate air brake systems with a single set of controls.

Be sure to activate the appropriate turn signal well in advance of a turn or lane change. Signal continuously throughout the turn and make sure to cancel the signal after the turn is completed, if your vehicle doesn't have self-canceling signals.

If your license to operate your personal vehicle is revoked, canceled, or suspended, you may not obtain a hardship license to operate a CMV.

The purpose of an Anti-Lock Braking System (ABS) is to prevent wheels from locking up during hard applications of the brakes, especially on slippery surfaces.

Without a working Anti-Lock Braking System (ABS), your vehicle will still have normal brake function. Continue to drive and brake as you normally would and have your ABS serviced as soon as possible.

When operating a new vehicle, you should familiarize yourself with its features and equipment before getting behind the wheel.

In an air brake system, the air storage tanks must be drained to remove accumulated water and compressor oil. Failing to do so can cause damage. Manually operated drains should be used at the end of each day of driving.

It is important for you to be aware of your surroundings at all times. To do this, regularly check your mirrors.

It is illegal to operate a CMV if your blood alcohol concentration (BAC) is 0.04 percent or higher. A first offense will result in the loss of your CDL for one year. A second offense will result in the loss of your CDL for life.

When turning or changing lanes, you should signal early and signal continuously. Cancel your turn signal once the turn or lane change is complete.

In general, a smaller vehicle will be able to come to a complete stop faster than a larger vehicle. Keep this in mind when determining your following distance.

If you are convicted of any traffic violations while driving any vehicle, you must notify your employer within 30 days of the conviction. This rule excludes parking violations.

Vehicles with Anti-Lock Braking Systems (ABS) have yellow malfunction lamps.

Controlled braking is the method of applying a vehicle's brakes as hard as possible without locking the wheels. A driver should keep steering wheel movements very small if braking while using this method.

When accelerating, speed up smoothly and gradually so the vehicle does not jerk. Rough acceleration can cause mechanical damage.

On flatbed trailers and trailers without sides, cargo needs to be tied down. There should be at least one tie-down for every 10 feet of cargo. Regardless of the size of the cargo, at least two tie-downs must be used.

Always decrease your speed when traveling through a construction area. Slow down even further if there are workers on or near the roadway.

You will be denied a hazardous materials endorsement, or lose an existing endorsement, if you renounce your U.S. citizenship; are not a lawful permanent U.S. resident; are wanted for, indicted for, or convicted of certain felonies; are judged mentally defective or are committed to a mental institution; or are deemed by the Transportation Security Administration (TSA) to pose a security threat.

If you are fatigued, you will not see or react to hazards as quickly as you would if you were fully energized and awake. You will be impaired in making critical decisions.

Most good drivers consistently look down the road 12 to 15 seconds ahead of their vehicles. Watching ahead of your vehicle will allow you to react to upcoming hazards before meeting them.

If you must drive in reverse, you should first walk around your vehicle to look at the path of travel and check for obstacles. Because mirrors have blind spots, you cannot rely exclusively on them. It is recommended to use a helper whenever possible.

Operating oil pressure should be between 35 and 75 psi. Do not operate a vehicle if it has oil pressure that is low, dropping, or fluctuating.
