Optional when transporting hazardous materials.
With some exceptions, you must have a tank endorsement to transport liquids or gases. This applies to both hazardous and non-hazardous substances.

The ABS needs to be activated.
Vehicles with Anti-Lock Braking Systems (ABS) have yellow malfunction lights to alert the driver if something is wrong with the braking system. If these lights activate, the driver may have lost ABS on one or more wheels.

The brake knob should be pushed in.

Brakes are designed to take a lot of heat, but drivers should not rely solely on the brakes to slow their vehicle. Brakes may fade and lose their ability to slow down the vehicle if they become too hot, so drivers should also rely on the engine braking effect.
12 . Emergency brakes are:
Only required when transporting hazardous materials.
All trucks, truck tractors, and buses must be equipped with emergency brakes and parking brakes.
