Talk to other people.

Attend hazardous materials training courses.

Guess.

Load the containers by hand.

Use the vehicle’s emergency brake.

Ask someone to help you.

3 . Shippers must label hazardous materials. If an item is smaller than its label, how should the item be labeled?

The item may be tied together with other hazardous materials and labeled with a sheet of paper on the outside of the bundle.

The label may be attached to a tag that is securely attached to the package.

The item may be marked with a large orange dot.

The item may be placed in a box displaying a warning label.

Shippers must place diamond-shaped hazard warning labels on most packages of hazardous materials. If the label won't fit on the package, it can be placed on a tag that is securely attached to the package.

4 . When a driver is not in their vehicle, hazardous materials' shipping papers should be:

Kept on the driver's person.

Kept on the driver’s seat.

Kept under the passenger’s seat.

Placed on the dashboard.

5 . When approaching a railroad crossing while transporting chlorine:

You must stop before crossing the tracks.

You must reduce your speed before crossing the tracks.

You can proceed without stopping if no warning lights are flashing.

You can proceed without stopping if no other vehicles are within sight.

6 . If you are transporting explosives and your vehicle breaks down, you may notify other drivers:

With flares.

With electric lights.

By standing on the roadway and waving your arms.

By keeping the driver's side door open.

If your vehicle breaks down on the road while you are transporting explosive materials, you must warn other drivers. Put out warning signals like reflective triangles or electric lights if you are carrying Division 1.1, 1.2, or 1.3 explosives. Do the same if you are driving a tank used to transport Class 3 flammable liquids or Division 2.1 flammable gases, even if the tank is empty. If transporting flammable materials, do not use warning signals that could cause your cargo to catch fire.
