A vehicle inspection report keeps the carrier informed about any problems that need to be fixed.

The liver removes alcohol from the body at a fixed rate, so the only way to sober up after consuming alcohol is to allow your body time to remove the alcohol on its own.

As you exit 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 control skills test.

When inspecting your tires, verify that there is tread depth of at least 4/32 of an inch in every major groove on the front tires and tread depth of at least 2/32 of an inch in grooves on the other tires. Be sure that your tires are not too worn, are not cracked, have proper air pressure, and are all equally sized.

If you begin to feel drowsy while driving, the best thing to do is to stop and get some sleep. A driver trying to push on and finish a trip while fatigued is a major cause of fatal accidents.

Many large vehicles have curved, convex mirrors. Convex mirrors allow drivers to see a wider area than flat mirrors. However, they also make objects seem smaller and farther away than they really are.

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

The body removes alcohol at a fixed rate. The more alcohol consumed, the longer it will take for the body to remove the alcohol from its system.

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.

If your hydraulic braking system will not build up the pressure needed to slow or stop your vehicle, there are a few possible solutions. Try shifting into a lower gear, pumping the brakes, and/or using the emergency brake.

However you choose to deal with a brake failure on a downhill slope, it is important that you make your decision as quickly as possible. The longer you wait to act, the faster your vehicle will be moving, and the harder it will become to stop.

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 your vehicle for an inspection, you should look underneath the vehicle for fresh leaks of oil, coolant, grease, or fuel. Seeing a fresh puddle of any of these fluids could indicate a safety issue with your vehicle.

Missing clamps, spacers, studs, or lugs are dangerous, as are mismatched, bent, or cracked lock rings. Be sure your tires and rims are in good condition before operating your commercial motor vehicle.

After starting the engine of a vehicle equipped with an Anti-Lock Braking System (ABS), the indicator light should come on and then turn off. If the light stays on, something is wrong with the ABS.

When stopped, a bus driver should warn exiting passengers to watch their step when leaving the bus.

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

Explosives are placed in hazardous materials Class 1.

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.

The person driving a vehicle is responsible for its safe operation. Be sure to perform routine vehicle inspections before operating a commercial motor vehicle.
