A vehicle being equipped with anti-lock brakes on only the tractor or only the trailer provides additional control during braking.

The tractor and trailer can still be used together.

The truck should not be driven because ABS needs to be on both the tractor and trailer.

The truck should be driven more slowly than usual.

The tractor should not be used and a new tractor with ABS should be located.

The tractor and trailer can still be used together.

If an Anti-Lock Braking System (ABS) is not working, the vehicle's basic braking functions are still intact. The driver should continue to drive and brake in a normal fashion.

Use their parking brake to stop.

To correct a drive-wheel braking skid, you should first remove your foot from the brake pedal to allow the locked wheels to begin rolling again. Quickly steer in the direction you want to go, then countersteer to prevent your vehicle from skidding in the opposite direction.

Remove your foot from the brake pedal.

Turn quickly in the direction of the skid.

Countersteer after the vehicle is back on course.

Because there are many different types of tanks, each of which with its own specific features, a driver should always consult the operator's manual for information on how to inspect a particular tank.

Refer to their specific vehicle’s operator manual.

Look online for information about the vehicle.

Make sure there is no rust on the outside of the tank.
