The securement of cargo must be checked before beginning a trip, within the first 50 miles of a trip, and then again every three hours or 150 miles.

If you must stop on the side of the road, it is important to turn on your four-way emergency flashers to warn other road users.

Be cautious when driving near people who are working on a disabled vehicle on the side of the road. They may be focused on the repair and not paying attention to nearby traffic.

The faster you drink, the higher your blood alcohol content (BAC) will become. The liver removes alcohol from a body at a fixed rate of about one drink per hour.

Hydroplaning is most likely to occur when driving on wet roads with tire pressure that is too low and tire tread that is too worn. If there is enough water on the road, hydroplaning can occur at speeds as low as 30 mph.

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.

When examining the air and electrical lines as part of your vehicle inspection test, you must listen for leaks. Ensure that the air hoses and electrical lines are not cut, chafed, spliced, or worn. Make sure air and electrical lines are not tangled, pinched, or dragging against tractor parts.

To maintain proper control of your vehicle, the steering wheel should be held firmly with both hands. Your hands should be positioned on opposite sides of the wheel.

An Anti-Lock Braking System (ABS) is in place as an addition to a braking system. It intervenes to prevent brakes from locking up during hard braking. If ABS is not working, the basic braking functions on a vehicle will still remain, so the driver can continue to drive and brake normally.

When inspecting an exhaust system, you should verify that parts of the system are not loose, broken, or missing. The system's parts must be properly mounted and should not be rubbing against moving parts of the vehicle.

You should not refuel a bus while passengers are on board, unless it is absolutely necessary to do so. In particular, never refuel a bus carrying passengers while inside an enclosed building.

When checking your vehicle's tires, you should confirm that air pressure is neither too low nor too high; that there is at least 4/32 of an inch of tread depth in every major groove on the front tires; and that radial and bias-ply tires are not used together.

If you are involved in a crash, the three basic things you need to do are protect the area, notify the proper authorities, and care for anyone injured. It is important to protect the accident site immediately after the accident occurs to help prevent another crash from happening in the same location.

Aggressive driving is defined as operating a motor vehicle in a selfish, bold, or pushy manner, without regard for the rights or safety of others.

When driving a bus, be aware of how quickly it can accelerate and much space it takes up on the roadway. Always wait for a gap in traffic that is large enough to accommodate your vehicle before you leave a stop.

In construction zones, do not exceed the posted safe sped limit. Slow down even more when workers are near the roadway.

During the on-road driving skills test, make sure you do not put your vehicle over curbs, sidewalks, or lane markings. Stop behind stop lines, crosswalks, or stop signs. On multiple-lane roads, complete turns in the proper lane. Always move to or remain in the rightmost lane, unless the lane is blocked.

A maximum posted speed limit is the fastest a vehicle may travel under ideal circumstances. A driver should decrease their driving speed as conditions require. A driver should never exceed the legal speed limit.

When doing a pre-trip inspection on a vehicle with power steering, be sure to check the hoses, pumps, and fluid level. In particular, you should check the hoses for leaks.

If your vehicle begins to hydroplane, do not apply the brakes. Instead, slow down by releasing the accelerator and pushing in the clutch.
