New Mexico CDL Permit Test - Tank

When driving at dawn, at dusk, or in inclement weather, you should use your headlights on their low beam setting to increase your visibility.

Your truck may block the views of drivers behind you, making them unaware of any upcoming hazards that require you to stop. For this reason, it is a good idea to flash your brakes and warn other drivers before slowing or stopping.

Black ice is a thin layer of ice that is clear enough for the road surface to be seen through it. A road covered in black ice may look like it is merely wet. You should be very careful when temperatures are below freezing and the road looks wet.

Many hazardous materials classified as poisonous are also flammable.

Smooth bore tanks lack internal baffles. Compared to other types of tanks, unbaffled tanks are the most prone to front-to-back surge.

Always change lanes slowly and smoothly. If you did not see drivers who are already using the lane you wish to occupy, this will give them a chance to get out of your way or honk their horns to alert you. Always signal when changing lanes.

Defects in an exhaust system are very dangerous because they can cause poisonous fumes to enter the cab or sleeper berth.
