1 . To prevent a rollover, a driver should:

Turn quickly. Rollovers can happen when a combination vehicle is turned too quickly. To help prevent the risk of rollover, it is important to keep the vehicle's center of gravity low by loading cargo as close to the ground as possible.

2 . After finishing a pre-trip inspection, you should:

Leave the rear shut-off valves open. Before a trip, you should ensure that air reaches all air brakes on all trailers by opening up the rear emergency line and service line shut-off valves to listen for escaping air. Close both shut-off valves before beginning to drive.

3 . To test the trailer service brakes, you should:

Move the vehicle forward slowly and apply the brakes with the hand control. To test the trailer service brakes, you should first ensure that the braking system has a normal air pressure level, then release the parking brake. You should then move the vehicle forward slowly and apply the brakes with the hand control. If the trailer service brakes are working properly, you will feel the brakes activate.

4 . One way to prevent a rollover is to:

Keep cargo as far from the ground as possible. A rollover is more likely if cargo is unevenly loaded in a rig. To help prevent a dangerous rollover, it is important to keep a load as centered on the rig as possible.

5 . Rollovers happen when drivers:

Drive illegally. A rollover happens as a result of a driver taking a turn at too high a speed. Be sure to take turns and curves safely and slowly.

6 . To help prevent rollovers, you should:

Keep the load on one side of the trailer. To lower the risk of a rollover, load your cargo as closely to the ground as possible. To further reduce this risk, take curves and corners slowly.

7 . Starting in which year were newly manufactured trailers required to have ABS?

2004 All trailers and converter dollies manufactured on or after March 1, 1998 must be equipped with Anti-Lock Braking Systems (ABS).
