1 . To correct a drive-wheel braking skid, a driver should do all of the following, except:
Accelerate.
To correct a drive-wheel braking skid, you should first remove your foot from the brake pedal to allow the locked wheels to begin rolling again. Quickly steer in the direction you want to go, then countersteer to prevent your vehicle from skidding in the opposite direction.
2 . If another driver is following you too closely, you should do all of the following, except:
Avoid relying on tricks to help others pass.
If you are being followed too closely, you should increase your following distance, avoid making quick moves, and avoid relying on tricks (such as flashing your lights) to help other drivers pass. Speeding up may only increase the danger by causing the tailgater to continue tailgating you at a higher speed.
3 . Talking on a hands-free phone while driving:
While speaking on a hands-free phone while driving is less dangerous than speaking on a hand-held phone, it is just as likely to mentally distract a driver. Simply engaging in conversation takes their mental focus away from the task of driving.
4 . Brake linings should be:
Brake linings should not be loose or soaked with oil or grease. They shouldn't be dangerously thin.
5 . What kind of brakes do most newer heavy-duty trucks use?
Most newer heavy-duty vehicles use dual air brake systems. A dual air brake system has two separate air brake systems which use a single set of brake controls.
6 . When making a left turn, you should start the turn:
When making a left turn, you should wait until you reach the center of the intersection before actually beginning to turn. Due to off-tracking, the left side of your vehicle could hit another driver if you begin turning too early.
7 . What do air brakes use to make the brakes work?
Many large CMVs are equipped with air brakes. An air braking system uses compressed air to operate.
