15 . When driving, keeping space between your vehicle and other vehicles is:

Optional. For the safety of everyone on the road, it is essential that you maintain adequate cushions of space between your vehicle and other vehicles. This will help ensure that if you need to stop your vehicle, you will be able to do so without hitting someone else.

16 . To prevent fatigue while driving, you should:

Close the vents. A hot, poorly-ventilated area can make a person sleepy. Opening a window, opening a vent, or using the air conditioning can help keep the cab cool and reduce the risk of fatigue.

Should be lifted with a jack. Your vehicle's engine may need to be running in order for you to check the level of its automatic transmission fluid.

18 . If a CMV driver operates a CMV with a detectable blood alcohol concentration (BAC) that is lower than 0.04 percent, they will be:

Told to drive home. 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.

19 . When should you check and adjust your mirrors?

Mirrors do not need to be adjusted. The adjustment of mirrors must be checked prior to the start of any trip.

20 . If federal inspectors judge your vehicle to be unsafe, they can:

Pull the vehicle out-of-service until it is fixed. If a federal or state inspector judges a CMV to be unsafe, they may put it out-of-service until it is fixed.

21 . While driving, if it is discovered a vehicle's ABS is not working, the driver should:

Use their parking brake to stop. 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.
