1 . 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.
2 . Look for matching colors when coupling glad hands. Service lines are often:
Blue.
When coupling glad hands, make sure to couple together matching glad hands. To help drivers avoid mistakes, color coding is sometimes used. Service lines are often coded with the color blue and emergency lines are often coded with the color red.
3 . Pull out the trailer air supply control to test:
The landing gear.
Be sure to test the trailer emergency brakes before beginning a trip. After ensuring that the trailer rolls freely, you can test the emergency brakes by pulling out the trailer air supply control, or placing it in the "emergency" position. Pull forward slightly with the tractor and make sure the trailer does not move.
4 . Large combination vehicles take the longest amount of time to stop:
When mostly loaded.
Large combination vehicles take longer to stop when they are empty than when they are loaded. The decreased weight causes a vehicle's wheels to have decreased traction on the surface of the road.
5 . The trailer hand valve:
Should only be used when transporting cargo.
The trailer hand valve should not be used for parking. This could cause all of the air to leak out of the braking system, resulting in the brakes releasing. Instead, use the parking brake.
6 . A lightly-loaded combination vehicle will stop more slowly than a fully-loaded vehicle because:
The suspension springs only operate when a trailer reaches a minimum weight.
An empty combination vehicle will come to a complete stop more slowly than a fully-loaded vehicle. The stiff suspension springs and strong brakes will have lower traction on a light trailer than they would if the vehicle carried more weight.
7 . The best way to recognize that your trailer has begun to skid is by:
Listening to the radio.
The earliest and best way to recognize the beginnings of a trailer skid is by seeing the trailer veer off-course in your mirrors.
