Left on.

Unless you must run the engine to operate a pump, you should always turn off the engine before loading or unloading flammable liquids.

An explosive.

Radioactive.

Corrosive.

The first hazardous materials class includes explosives such as ammunition, dynamite, and fireworks.

Allows you time to make a plan to avoid an upcoming hazard.

Always watch for hazards on the road ahead. Doing this will allow you time to react to hazards before meeting them.

Potential warning signs of fatigue include difficulty focusing, frequent blinking, or heavy eyelids; yawning repeatedly or rubbing your eyes; daydreaming; wandering or disconnected thoughts; trouble remembering the last few miles you've driven; missing exits or traffic signs; having trouble keeping your head up; drifting from your lane; following too closely; hitting a shoulder rumble strip; or feeling restless and irritable.

7. If there is a fire in your vehicle and you are not sure how to extinguish it, you should:

Use a fire extinguisher.

Try douse the flames with water.

Move away from the flames and wait for the firefighters.

If you are not sure which method to use when putting out a fire, do not attempt to extinguish the fire on your own. Instead, wait for firefighters to arrive and let them handle it. This is especially true if you are experiencing a hazardous materials fire.
