If a tractor-trailer is so equipped, the trailer brake hand valve can be used to stop the vehicle from rolling back when being started from a stop.

Always signal continuously through a turn. Do not cancel a signal until the turn is finished.

To reduce the chances of becoming fatigued on a long trip, a driver should stop for a break at least once every two hours or 100 miles driven.

A common cause of vehicle fires in the aftermath of an accident is the improper use of flares near spilled fuel. Use flares with caution.

Check your tires regularly when looking in your mirrors. This helps ensure that you will notice a tire fire, if one should happen. Tire fires may occur when a tire is under-inflated, if dual tires are touching, or if the tires are otherwise overheated.

Driving while fatigued can be extremely dangerous. Strategies for preventing drowsiness while driving include getting a full night's sleep before a trip; having someone ride with you so you can take turns driving; scheduling trips for times during which you are normally awake; and avoiding medications that may cause drowsiness.

Many large vehicles have curved, convex mirrors. Convex mirrors allow drivers to see a wider area than flat mirrors. However, they also make objects seem smaller and farther away than they really are.

To reduce the risk of distraction, do not engage in complex or emotionally intense conversations while driving. Pre-programming radio stations before your trip and avoiding eating, drinking, or smoking while at the wheel can also help you avoid becoming distracted while driving. Remember that mental distractions that take your attention away from the task of driving can be just as dangerous as physical distractions.

Many charter and intercity carriers have rules about passengers smoking, drinking, and using music players while on the bus. Explaining passenger rules at the start of a trip is often an effective way to avoid trouble later on.

Ice becomes wet when the weather is just warm enough to melt the ice slightly. Wet ice is much more slippery than ice that is not wet.

The average driver has a reaction time of between three-quarters of a second and one second.

When stopping a bus at a railroad crossing, you should open your forward door if doing so will improve your ability to see or hear an approaching train.

Good drivers scan the road at least 12 to 15 seconds ahead of their vehicles. Looking ahead will allow you to identify and react to hazards before meeting them. Be sure to specifically look for vehicles that are coming onto the highway, entering into your lane, or turning.

When driving in reverse, it is always recommended that a driver backs their vehicle toward its left side. This will allow the driver the best possible view of the rear of their vehicle.

While buses may carry some hazardous materials under certain conditions, they must never be used to transport tear gas or irritating materials.

People sometimes damage unattended buses. Before beginning a trip, a bus driver should check the interior of a bus to verify that key systems are in good condition for rider safety.

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.

You should only sign a previous inspection report if defects were either noted and certified to have been repaired or if repairs were not needed.

Keep an eye on the gauges after starting the engine. The coolant temperature gauge should begin a gradual rise to the normal operating range.

A vehicle inspection report keeps the carrier informed about any problems that need to be fixed.
