Never use the right lane.

The gearshift should be in first gear.
Before inspecting the engine compartment, make sure that the parking brakes are on and/or the wheels are chocked. Check the engine compartment before entering the cab and starting the engine.
18 . You should always be able to stop within:
A minute of hitting the brakes.
You should always make sure that your vehicle will be able to stop within the area of the road that you are able to see. This means that you must slow down whenever conditions reduce visibility.
19 . Why are roads especially slippery right after it begins to rain?
Tires are not usually designed to drive in rain.
In rainy weather, roads are often at their most slippery when the rain first begins to fall. Fresh rainwater mixes with oil and grease on the road to form a slick film. As the rain continues, this mixture will eventually wash away.
20 . The service brake system:
Applies and releases the axle brake.
Air brakes consists of three separate braking systems: the service brake system, the parking brake system, and the emergency brake system. The service brake system applies and releases the brakes when you use the brake pedal while driving normally.
