Flashcard 11 - Doubles/Triples Flashcard Set for the CDL
Back
Pull the tractor close to the trailer and connect the emergency brake line, charge the air tank, and then disconnect the line.
Explanation:
Connecting double and triple trailers can be very dangerous if they are not equipped with spring brakes. If you have any doubt about the brakes being set, chock the wheels.
