1 . 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.
2 . What happens when the wheels of a trailer lock up?
The trailer will stop.
A trailer tends to swing around, potentially resulting in a trailer jackknife, if its wheels lock up.
3 . The trailer hand valve should:
Be used on slippery surfaces.
The trailer hand valve works the trailer brakes but should only be used when testing them. Using it while driving could create a skid. Never use the trailer hand valve while parking because doing so may release the air pressure from the braking system, releasing the brakes that are holding the vehicle in place.
4 . A tractor protection valve is:
A device that allows the battery to recharge efficiently.
On combination vehicles with air brakes, the tractor protection valve keeps air in the tractor or truck brake system, should the trailer develop a bad leak or break away from the tractor.
5 . The emergency air line:
Prevents skids.
The emergency air line (also known as the supply line) has two functions. The first is to supply air to the trailer air tanks on a combination vehicle, and the second is to control the emergency brakes.
6 . 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.
7 . When glad hands are coupled, the seals should be pressed together at an angle of:
90 degrees.
When coupling, be sure to couple the proper glad hands. When glad hands are connected, the seals should be pressed together at a 90-degree angle.
