15 . If being tailgated, you should open up your following distance.
If someone is tailgating you, it is a good idea to open up the space ahead of your vehicle to make it easier for the driver to pass you. Increasing your speed is not a good idea because the driver may continue to tailgate you at the higher speed, only increasing the danger.

Truck tractors with air brakes built on or after March 1, 1997 must be equipped with an Anti-Lock Braking System (ABS).
17 . In very hot weather, tires may catch fire.
Tires are especially prone to overheating in very hot weather. Under such conditions, stop driving periodically to ensure that your tires are not at risk of blowing out or catching fire.
18 . Empty trucks often take a shorter distances to come to a complete stop than fully-loaded trucks.
The brakes, tires, springs, and shock absorbers on heavy-duty vehicles are designed to work best when the vehicle is fully loaded. Empty trucks require longer distances to stop because their lighter weight allows them less traction.
19 . Noting the engine speed is one way to determine when to upshift.
There are two indicators that determine when you need to shift into a higher gear. One indicator is the engine speed (rpm). You should read your vehicle's manual to learn its rpm range and shift up when you reach the top of that range. The other indicator is road speed (mph). You should learn which speeds each gear can accommodate, then keep an eye on the speedometer and shift up as needed.
20 . How many seconds of following distance per every 10 feet of vehicle should you maintain when traveling more slowly than 40 mph?
Four seconds
When traveling at speeds below 40 mph, you should maintain at least one second of following distance for every 10 feet of your vehicle's length. At higher speeds, add an additional second.
21 . If stopped on the side of the road, how should you alert other motorists?
Keep the driver's side door open.
