In front of the driver's side of the vehicle.

2 . To make it easier to leave a parked position, you should park:

In a way that allows you to back up when exiting.

Only on the side of roadways, not in parking lots.

Backing is always dangerous and should be avoided whenever possible. When parking, look to park in a space that will allow you to pull forward when exiting.

They are working properly.

They need to be checked.

They will be the most effective.

If the brakes pull to one side or the other when used, it is an indication of brake trouble.

4 . On a shipping paper describing both hazardous and non-hazardous materials, the hazardous materials may be identified by being:

Listed first.

Written in pencil.

6 . If you plan to slow down, you can warn drivers behind you by:

Slamming on the brakes.

Tapping the brakes a few times and before braking.

Turning on one set of turn signals.

Use only the rear flashing lights.

Use only one set of turn signals.

Use your four-way flashers.

Always turn on your four-way emergency flashers if you must park on the side of the road. This is especially important when traveling at night.
