9 . Test the low pressure warning signal:
Before every trip.
It is essential that your low pressure warning light function properly. After allowing the system to charge, you can test the warning signal by rapidly applying and releasing the brake pedal.

The driver can choose which state’s laws to follow.
Commercial vehicle weight, securement of cargo, covering of loads, and where large vehicles can be driven are all regulated by federal, state, and local laws. These vary from place to place, so you must be aware of the rules that apply where you will be driving. State laws in the state in which you are driving take precedence.
13 . If something is found to be unsafe during a pre-trip inspection, you should:
Not use the items found to be unsafe, but may continue driving normally.
If a pre-trip inspection reveals anything unsafe about your vehicle, you must get it repaired. It is illegal to operate an unsafe vehicle.
14 . If a CMV driver operates a CMV with a detectable blood alcohol concentration (BAC) that is lower than 0.04 percent, they will be:

If you are found to be operating a CMV with any detectable amount of alcohol in your system, but you are still below the legal limit of 0.04 percent, you will be placed out-of-service for 24 hours. It is both illegal and dangerous to operate a motor vehicle while under the influence of alcohol.
