What does "trailering" refer to in relation to air brakes?

"Trailering" in relation to air brakes specifically refers to the act of connecting a trailer to a vehicle. This is an essential process that involves ensuring that the air brake system of the towing vehicle is properly hooked up to the trailer's brake system, allowing for synchronized braking. When a trailer is connected, it's crucial for the air brake lines to function effectively so that the brakes on both the truck and the trailer engage properly during operation, providing safe stopping and control.

If trailering is done correctly, it ensures that the air pressure from the towing vehicle adequately supplies air to the trailer's braking system. This allows the driver to maintain control over the trailer while it is being towed, thus enhancing overall safety on the road.
