Always turn off your vehicle's engine before loading or unloading explosive materials. Never drop, throw, or roll packages containing explosives.

A trailer tends to swing around, potentially resulting in a trailer jackknife, if its wheels lock up.

If your vehicle "pulls" to one side when braking, you may have brake trouble. If there is an issue with your brakes, you should fix the issue before driving. Operating an unsafe vehicle is against federal and state laws.

Be cautious when driving near people who are working on disabled vehicles. The task will likely consume their attention, so they may not be aware of traffic or other hazards on the road.

Before a trip, be sure to inspect all couplings. There should be no space between the upper and lower fifth wheel.

While shippers of hazardous materials are responsible for providing necessary placards, it is the driver's responsibility to actually place them on the vehicle.

The added weight of a heavy load will make a vehicle sit lower than usual. A vehicle will often be taller when carrying a light load than when carrying a heavy load. If your vehicle fits under an overpass while carrying a full load, it is not guaranteed that it will fit under the same overpass if it is empty.

If you must make a quick stop to avoid an accident while transporting liquid cargo, it may be a good idea to use the stab braking method. Remember that attempting to steer quickly while braking may cause your vehicle to tip over, especially if it has a high center of gravity.

The right lanes of a roadway are generally intended for vehicles traveling more slowly than surrounding traffic. If being slowed down by a heavy load, you should stay in the right lane.

Being properly rested is essential to the safe operation of a CMV. To maintain alertness, most people need eight to nine hours of sleep per night.

Always slow down before entering a foggy area. Use low beam headlights, avoid passing others, and avoid stopping on the side of the roadway. It is safest to completely avoid driving under foggy conditions, if possible.

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.

Bulkheads divide a large tank into multiple smaller tanks. A driver must pay special attention to weight distribution when driving a tank vehicle that has been separated by bulkheads.

Fatigue and lack of alertness are major hazards when driving at night. Most people are the least alert at night, especially after midnight.

If there is enough water on the road, hydroplaning can occur at speeds as low as 30 mph. It is most likely if the tires' air pressure is too low or if tires' tread is worn.

Stopping distance is affected by a vehicle's speed. The faster you are driving, the longer your stopping distance will become.

Commercial drivers are required by federal and state laws to inspect their vehicles before every trip. Regular inspections can help drivers identify issues before they become dangerous and costly.
