When inspecting a vehicle's exhaust system, be alert to a number of potential problems, including loose, broken, or missing exhaust pipes, mufflers, tailpipes, or vertical stacks; loose, broken, or missing mounting brackets, clamps, bolts, or nuts; exhaust system parts rubbing against fuel system parts, tires, or other moving parts of the vehicle; and exhaust system parts that are leaking.

You may be able to tell that another driver is distracted if you can see them drifting within a lane or across lane dividers; traveling at inconsistent speeds; being preoccupied with a cell phone, a map, food, or other items; or engaging in conversation with passengers.

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.

Commercial vehicles must be equipped with the appropriate emergency equipment. Equipment should include a fire extinguisher, emergency reflectors, and spare fuses, if applicable.

While driving, you should consistently check the road ahead for hazards. Develop a plan to deal with any hazards that could arise.

Increasing your vehicle's speed will increase your vehicle's striking power and braking distance. Doubling your vehicle's speed from 20 to 40 mph will multiply its braking distance by four.

Even under ideal weather conditions, a bus being driven at the posted design speed for a curve could either roll over or slide off the road. For safety, you should reduce your speed before driving a bus around a curve.

The driver's seat on a bus must be equipped with a seat belt, which the driver should always use.

Before a bus is brought to a complete stop at its destination, it is best for the driver to remind exiting passengers to take their carry-ons with them.

When inspecting an enclosed trailer as a part of the vehicle inspection test, check the front area of the trailer for signs of damage, such as cracks, bulges, or holes.

When approaching a curve during the on-road driving test, you should thoroughly check traffic in all directions. Before entering the curve, reduce your speed sufficiently so that further braking or shifting is not required. Keep your vehicle in its lane and continue checking traffic in all directions.

While a bus is traveling, passengers may not stand any farther forward than the rear of the driver's seat. To mark this barrier, a bus that is designed to allow passengers to stand must have a two-inch line on the floor (or some other means of showing passengers where they cannot stand). This is known as the standee line.

During the vehicle inspection test, you will need to show emergency equipment, including spare electrical fuses; three red reflective triangles, six fuses, or three liquid burning flares; and a properly charged and rated fire extinguisher.

If you observe a crash involving an aggressive driver, you should stop a safe distance from the crash scene, wait for police to arrive, and inform them of the aggressive behavior you witnessed.

When driving during the winter, it is particularly important that your tires have adequate tread. You need a tread depth of at least 4/32 of an inch in every major groove on the front tires, and at least 2/32 of an inch on the back tires. Check the tread depths by using a gauge.

If you must stop and park on the side of the road, make sure to turn on your emergency flashers. This is especially important at night. Taillights are not an adequate when alerting other drivers because the drivers may mistakenly think your vehicle is moving normally and collide with it.

Mandatory emergency equipment includes: at least one fire extinguisher; spare electrical fuses (unless the vehicle is equipped with circuit breakers); and warning devices for parked vehicles (such as reflective triangles).

Drivers are usually less alert when driving at night, especially after midnight.

A steering wheel with play of more than 10 degrees may be defective. On a 20-inch wheel, this is equal to about two inches of movement at the rim of the wheel.

A driver is allowed to exit their vehicle to check its position during any basic control skills test exercise. This action is called a "look." During the straight line backing exercise, a driver may not exceed one look. During any other exercise, a driver may not exceed two looks.
