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.

Smoking, eating, or drinking are distracting activities and should be avoided while you are driving. Instead, plan ahead and allow yourself time to stop to eat when making a lengthy trip.

You may be asked to complete a conventional parallel parking maneuver into a parking space that is to the right of your vehicle. You should drive past the parking space before backing into it while bringing the rear of your vehicle as close to the rear of the space as possible. Your vehicle should be completely within the boundaries of the space.

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

An Anti-Lock Braking System (ABS) intervenes to reduce brake pressure if there is a risk of wheel lockup. If the ABS isn't working, the vehicle's basic braking functions are not affected. A driver should continue to drive and brake in a normal manner.

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.

To help avoid frustration, which can lead to aggressive driving behavior, you should begin a trip with realistic expectations about your travel time. Plan ahead to allow time for potential traffic delays. Other strategies to help prevent aggressive driving behavior include driving an appropriate speed and keeping a reasonable following distance; avoiding making gestures at other drivers; and keeping your hands on the steering wheel.

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.

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.

For safe operation, a commercial motor vehicle needs a tread depth of 4/32 of an inch in every major groove on the front tires, and a tread depth of 2/32 of an inch on other tires.

When backing with a trailer, begin by turning the steering wheel in the direction opposite of the turn. Once the trailer starts to turn, reverse the direction of the steering wheel to follow the trailer.

To keep an engine fire from spreading, you should turn off the vehicle's engine as soon as possible. Do not open the hood if you don't have to.

You should accelerate very gradually when driving under slippery conditions. Using too much power in such conditions may cause you to lose control of your vehicle.

It is essential that a vehicle's engine have adequate oil pressure. An engine can be destroyed rapidly if it is run without oil.

Reduce your speed when traveling on surfaces that provide reduced traction. Reduce your speed by one-half or more when traveling on packed snow.

To avoid a loss of control, you should accelerate slowly when driving in poor-traction conditions, such as rain or snow.

You should stay in the right lane of a multilane road if your vehicle is being slowed down by a heavy load. Allow other vehicles to pass your truck using the left lane.

The main factors that determine a person's blood alcohol concentration (BAC) are how much alcohol has been consumed, how quickly it was consumed, and the person's body weight.

During a trip, you should regularly make checks to ensure that your vehicle is operating properly. Check the instrument panel and gauges; look at your mirrors; and examine the tires, cargo, and lights. Use all of your senses and be alert for anything that could be an early indication of trouble.

Regrooved, recapped, or retreaded tires are prohibited on the front wheels of a bus.
