You should accelerate very gradually when driving under conditions that create poor traction.
31 . If you’re feeling tired before a drive, you should:
Drive as fast as possible so you get to the destination quickly.
Stimulant drugs, including caffeine, are not helpful as a way of avoiding fatigue. They may help keep you awake, but will not make you any more alert. Feeling tired is a sign that your body needs sleep, and the only way to properly address it is to stop driving and get some sleep.
32 . If you are being tailgated, you should:
Allow the vehicle to pass.
If you are being tailgated, it is best to allow more room to open up in front of your vehicle. This will help you avoid the need for sudden stops, which could result in the tailgater rear-ending you, and will make it easier for the tailgater to pass. Speeding up may only make things more dangerous by prompting the other driver to continue tailgating you at a higher speed.
33 . When driving a vehicle equipped with an Anti-Lock Braking System (ABS), you should:
Brake with less force than you would in a vehicle not equipped with ABS.
When driving a tractor-trailer combination that is equipped with an Anti-Lock Braking System (ABS), you should brake in the same manner that you would if the vehicle was not equipped with ABS.
34 . When adjusting your mirrors before a trip:
When properly adjusted, your mirrors should each display some part of your vehicle. Being able to see your own vehicle in your mirrors will give you a point of reference when judging the positions of other objects.
35 . Rims with welding repairs:
Wheels or rims that have had welding repairs should never be used.
