1 . When you need to stop in an emergency, you should:

Lock the wheels and skid to a stop.

Stop in a way that keeps your vehicle in a straight line.

Stop in a way that turns your vehicle.

Expect your vehicle to slow down more quickly than usual.

If you need to make an emergency stop, you can use either the controlled braking method or the stab braking method. It's important to brake in a way that keeps your vehicle traveling in a straight line while still allowing you to turn, if necessary.

2 . In a dual air brake system:

Air tanks are shared between both systems.

Each system has its own air tanks.

You must designate which system you are using.

There are two air brake systems in a dual air brake system. The systems share a set of brake controls, but each system has its own tanks, hoses, and lines.

3 . If the low pressure warning light comes on while you are driving:

Braking will only occur if there is enough air in the tanks.

You can brake 14 times before the air in the system runs out.

You should continue to drive normally and check the brake system when it is convenient.

You should continue driving, but turn the emergency flashers on to warn other motorists.

If the low air pressure warning light turns on, you should stop and safely park your vehicle as soon as possible. Controlled braking will be possible only as long as enough air remains in the tanks.

4 . If the spring brakes are on, you should:

Not use the brake pedal.

Press the accelerator.

Move the steering wheel.

Be especially careful because the brakes may fail.

You should not apply the brake pedal if the spring brakes are activated. The brakes could be damaged if they are subjected to the force of air pressure and the springs at the same time.

5 . To ensure normal stopping power, drivers of vehicles equipped with a front brake limiting valve should:

Set the control to normal.

Set the control to the off position.

Set the control to the neutral position.

Some older vehicles have front brake limiting valves with "normal" and "slippery" settings. Setting a brake limiting valve to "slippery" reduces the vehicle's stopping power, so a driver should make sure the valve is in its "normal" position. Front wheel braking has proven to be effective in all driving conditions.

6 . If your tractor is equipped with ABS but your trailer is not, the ABS:

Will not be effective.

Will still improve your steering control.

Will make jackknifing easier.

Will allow others to see when you brake.

In a tractor-trailer combination, if the tractor is equipped with an Anti-Lock Braking System (ABS) but the trailer is not, the ABS will still improve the driver's steering control. The driver should keep an eye on the trailer and let up on the brakes if the trailer begins to swing out.
