Question: Why should we hook the emergency and air lines up before we back up under a trailer, as stated in #57? They didn't teach me this in school, but if this question is correct according to DOT, then that's fine.

[@AlexTruckUS]

You must lock the trailer brakes before backing beneath the trailer, which requires that you first confirm that the trailer brakes are operating. After testing the trailer brakes, connect the emergency and service airlines.

Please someone could tell me about these questions that all r correct im ready to take combustion test

[@2nd2none73]

I'm in trouble. I can't understand questions #48. And I've been a truck driver for 27 years

[@AlexTruckUS]

explanation Step 8: Supply Air to Trailer: From cab, push in \"air supply\" knob or move tractor protection valve control from the \"emergency\" to the \"normal\" position to supply air to the trailer brake system. After you connect the air lines but before backing under the trailer, the correct order of operations is essential for safety and functional reasons. Firstly, it's important to make sure the trailer brakes are engaged to prevent the trailer from moving unexpectedly when you back under it. After supplying air to the trailer system, and before coupling, check to ensure there are no people, obstacles, or any issues that could cause an accident or damage; this is when you'd walk around the vehicle. Lastly, pull the air supply knob to supply air to the system, and then couple the tractor with the trailer. This process ensures that the brakes are functioning correctly and that the trailer is safely connected.

[@05fordgtx1]

I disagree with question 57 you should lock your trailer in first

[@AlexTruckUS]

explanation Step 7: Connect Air Lines to the Trailer • Check the glad hand seals and connect the tractor emergency air line to the trailer emergency glad hand. • Check the glad hand seals and connect the tractor service air line to the trailer service glad hand. • Make sure the air lines are safely supported where they will not be crushed or caught while the tractor is backing under the trailer.

Is number 33 is correct ?

[@AlexTruckUS]

The trailer hand valve should be used only to test the trailer brakes. Do not use it in driving because of the danger of making the trailer skid. The foot brake sends air to all of the brakes on the vehicle (including the trailer(s)).
