Michigan CDL DMV Knowledge Test Class B 2

On vehicles with Anti-Lock Braking Systems (ABS), yellow malfunction lamps alert the driver to ABS malfunction.

All states share driver information through a computerized database in order to prevent the issuance of multiple licenses to a single person. It is prohibited for a person to have more than one driver license.

Vehicles equipped with Anti-Lock Braking Systems (ABS) have yellow malfunction lights to indicate issues in the braking system.

During the vehicle inspection test, you will be required to do a complete inspection of your vehicle. During this inspection, you must explain to the examiner what you are inspecting and why you are inspecting those items.

When inspecting a vehicle's suspension, you should look for broken or missing leaves in the leaf springs. Any defect of this kind is dangerous. If one-fourth or more of the leaves are missing from any leaf spring, the vehicle must be put out-of-service.

Potential warning signs of fatigue include difficulty focusing, frequent blinking, or heavy eyelids; yawning repeatedly or rubbing your eyes; daydreaming; wandering or disconnected thoughts; trouble remembering the last few miles you've driven; missing exits or traffic signs; having trouble keeping your head up; drifting from your lane; following too closely; hitting a shoulder rumble strip; or feeling restless and irritable.

A dual air brake system is made up of two separate air brake systems. If there is an air leak in one system, it may not affect the other.

Bridges tend to freeze before other parts of the roadway. Be particularly careful on bridges when temperatures are close to the freezing point.

If you encounter an aggressive driver, you should not let yourself be provoked by any angry gestures they make toward you. Avoid making eye contact with the other driver and do not try to race them.

Texting while driving a CMV is prohibited. "Texting" is defined as manually entering text into, or reading text from, an electronic device.

The suspension system performs the vital functions of holding up the vehicle and its load while keeping the axles in place. Defects in the suspension are therefore extremely dangerous.

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.

When inspecting a vehicle with a dual air brake system, you should wait for air pressure to build from 85 to 100 psi in both the primary and secondary systems. This should take about 45 seconds.

When turning, drivers usually look in the direction of their turn. If a driver fails to signal before a turn or lane change, their body movements may still provide a clue that they are planning to turn.

The examiner will score the number of times your vehicle touches or crosses an exercise boundary line. Each encroachment will count as an error, resulting in points against your skills test score.

If used and maintained properly, air brakes are a safe and effective way to stop large, heavy vehicles.

Speeding is the leading cause of death and injury in work zones. Use extra caution when driving near workers in a work zone.

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.

Avoid being an aggressive driver by being realistic about your travel time, making allowance for delays, maintaining reasonable following distances, and not making hand gestures that could anger another driver.

Even if they did not load or secure the cargo themselves, the driver of a vehicle is responsible for inspecting the cargo and ensuring that it is properly secured.

An encroachment during the basic vehicle control skills test is when an exercise boundary line is touched or crossed by any portion of the applicant's vehicle. Every encroachment will be counted as an error.

When inspecting a trailer coupling, you should make sure the fifth wheel locking jaws are closed around the shank of the kingpin, not the head of the kingpin.

In low temperatures, bridges usually freeze before other road surfaces. When driving in cold weather, especially when weather conditions have been wet, use special caution on bridges and overpasses.

Mirror adjustment should be checked prior to the start of each trip. Any attached trailer should be straight while mirrors are being adjusted.

A header board protects a driver from moving cargo in the event of a crash or emergency stop.

Containerized loads are generally used when freight is carried partway by rail or ship. Sealed materials cannot be inspected, but a driver should ensure that the containers do not exceed safe and legal weight limits.

The safety relief valve in an air brake system releases air if necessary to prevent pressure in the system from becoming too high. If the valve starts releasing air, there is something wrong. Have a mechanic fix the problem.

While driving downhill, you should hold down the brake pedal until your vehicle reaches a speed 5 mph below your safe speed, then release the brake pedal. Repeat this process.

Rust around wheel nuts may mean that they are loose. Check the tightness of the nuts if you see any rust in the area.

If your brakes fail on a downgrade, you will need to quickly find something outside that can stop your vehicle. An escape ramp is the best option. If no escape ramp is available, use the least hazardous available option, such as driving into an open field or side road that flattens out or turns uphill.

A driver must be at least 21 years old to operate a CMV in interstate commerce. Drivers may be 18 years old to drive a CMV only within the state of Michigan.

Poorly balanced cargo can cause a vehicle to be difficult to handle. Keep weight distribution in mind when loading cargo.

When stopped on the side of the road, be sure to turn on your vehicle's four-way emergency flashers, especially during times of lowered visibility. Place warning devices within 10 minutes of being stopped.

Slow down and be especially careful when driving in and around work zones, in places where the pavement drops off sharply at the edge of the road, when foreign objects are present on the road, and on freeway on- and off-ramps.

Transporting cargo that is loaded with a high center of gravity increases the risk that the transporting vehicle will tip over. Cargo should be loaded with a safe weight distribution.
