Tar in the road pavement frequently rises to the surface in very hot weather. Spots where tar "bleeds" to the surface are very slippery.

Use Your Seatbelt! The driver's seat should have a seat belt. Always use it for safety.

With the stab braking method, you apply your brakes all the way and release brakes when wheels lock up.

You cannot inspect sealed loads, but you should check that you don't exceed gross weight and axle weight limits.

Most good drivers look at least 12 to 15 seconds ahead. That means looking ahead the distance you will travel in 12 to 15 seconds.

As part of your Vehicle inspection, make sure the truck is not overloaded and the cargo is balanced and secured properly. You need to inspect again: after you have driven for 3 hours or 150 miles, and after every break you take during driving.

No matter how small the cargo, it should have at least two tie-downs.

Use of drugs can lead to traffic accidents resulting in death, injury, and property damage. Furthermore, it can lead to arrest, fines, and jail sentences. It can also mean the end of a person's driving career.

Poor weight balance can make vehicle handling unsafe. Too much weight on the steering axle can cause hard steering. It can damage the steering axle and tires.

Be prepared to "counter-steer," that is, to turn the wheel back in the other direction, once you've passed whatever was in your path. You should think of emergency steering and counter-steering as two parts of one driving action.

Class A is for trash, wood and paper, Class B is for liquids and gases, and Class C is for energized electrical sources, so all answers are correct.

Here are some signs of slippery roads: shaded areas, bridges, melting Ice, black Ice makes the road look wet, and just after rain begins.

Hitting overhead objects is a danger. Make sure you always have overhead clearance.

Cargo should have at least one tie-down for each ten feet of cargo. Make sure you have enough tiedowns to meet this need. For a 20-foot load you would need at least 2 tie downs.

Cargo should have at least one tie-down for each ten feet of cargo. Make sure you have enough tiedowns to meet this need.

If possible, avoid using the brakes until your speed has dropped to about 20 mph, and gently return to the road.

Covering the brake involves taking your right foot off the accelerator and holding it over the brake pedal. Your foot should hover over the pedal and not rest on it in any way.

When exiting the expressway: Make necessary traffic checks, use proper signals, decelerate smoothly in the exit lane.

You should always be able to stop within the distance you can see ahead. At night, you can't see as far with low beams as you can with high beams. When you must use low beams, slow down.

Check wheel bearing seals to make sure they are not leaking.

Convex mirrors present a view of people and objects that does not accurately reflect their size and distance from the vehicle.

Some liquid tanks are divided into several smaller tanks by bulkheads. When loading and unloading the smaller tanks, the driver must pay attention to weight distribution.

Vehicles must be equipped with emergency equipment. Look for: fire extinguisher(s), spare electrical fuses (unless equipped with circuit breakers), and warning devices for parked vehicles.

Here are some rules to follow in putting out a fire: When using the extinguisher stay as far away from the fire as possible and aim at the source or base of the fire not up in the flames.

Wait for normal air pressure, release the parking brake, move the vehicle forward slowly about five mph, and apply the brakes firmly using the brake pedal. Note any vehicle "pulling" to one side, unusual feel, or delayed stopping action.

Gasoline fires may be extinguished by smothering with wet rags, woolen cloth, sand, earth or ashes.

When driving in heavy rain or deep standing water, your brakes will get wet. Water in the brakes can cause the brakes to be weak, to apply unevenly, or to grab. This can cause lack of braking power, wheel lockups, pulling to one side or the other, and jackknife if you pull a trailer.

Identify, Predict, Decide, and Execute (IPDE) is the step-by-step process behind the principles of defensive driving and complexities of visual perception in traffic.

On packed snow, reduce speed by a half, or more. If the surface is icy, reduce speed to a crawl and stop driving as soon as you can safely do so.

Tie-downs must be of the proper type and proper strength. Federal regulations require the aggregate working load limit of any securement system used to secure an article or group of articles against movement must be at least one and one-half times the weight of the article or group of articles.

Dry bulk tanks require special care because they have a high center of gravity, and the load can shift. Be extremely cautious (slow and careful) going around curves and making sharp turns.

Your best hope is an escape ramp. If there is one, there will be signs telling you about it. Use it. Ramps are usually located a few miles from the top of the downgrade. Escape ramps save lives, equipment and cargo.

Never remove the radiator cap or any part of the pressurized system until the system has cooled. Steam and boiling water can spray under pressure and cause severe burns.

It's natural to want to brake in an emergency, however, braking when a tire has failed could cause loss of control. Once the vehicle has slowed down brake very gently, pull off the road, and stop.

Drivers of modern trucks may have to use lower gears going down a hill than would be required to go up the hill.

Skids caused by acceleration usually happen on ice or snow. Taking your foot off the accelerator can easily stop them. If it is very slippery, push the clutch in. Otherwise, the engine can keep the wheels from rolling freely and regaining traction.

Some drivers make the mistake of always using low beams. This seriously cuts down on their ability to see ahead. Use high beams when it is safe and legal to do so. Use them when you are not within 500 feet of an approaching vehicle.

It will take longer to stop, and it will be harder to turn without skidding, when the road is slippery. Reduce speed by about one-third on a wet road. On packed snow, reduce speed by a half, or more. If the surface is icy, reduce speed to a crawl and stop driving as soon as you can safely do so.

There are two basic reasons for covering cargo: to protect people from spilled cargo, and to protect the cargo from weather. Spill protection is a safety requirement in many states. Be familiar with the laws in the states you drive in.
