This is true. It is best to get to the inside cab early. If you do not make it to the inside can you can automatically fail for not doing the CDL air brakes test.

All these items will all appear on your CDL pre-trip. The correct answer is none of these.

Both the fuel and air tanks should be checked for proper mount, no leaks, and good hoses. Only the fuel tank will have a cap so you may fill the tanks.

Make sure the steps are properly mounted, no damage, and bolts are present and secure.

Handrails will need to be tight and secure, properly mounted, all bolts in place, and no excessive damage.

We suggest checking the seat and belt for securement and damage before sitting down. You will be in a hurry, and it is best to mention them when you see them.

As soon as you sit in the driver's seat please buckle your seatbelt. If you move the vehicle at all without your seatbelt fastened it is an automatic fail.

If you checked them for mounts, cracks, and clean while outside of the vehicle there is no need to state those again. Adjustment can only be checked from the driver's seat, but if you forgot to mention the mirrors on the outside of the vehicle you can check them now for everything.

If you just mention the wipers and do not check to make sure they work you will not get credit for them. This is true with all the answers here.

Steering wheels should not have more than 2" of play or 10 degrees in a 20" wheel.

Making sure the vehicle is in neutral, parking brake set, and seat belt on is steps to a safe start of the vehicle. You should also apply the clutch if equipped before starting.

We do not check the water pressure gauge, instead you should check the water temperature gauge.

Air pressure should rise to between 120-140 PSI.

The voltmeter should be between 12-14, and in the green to be working properly.

The temperature gauge will more than likely not move until the vehicle starts to warm up.

You need to make both the air and city horns work to get credit for checking them.

You will need to check and make each light indicator work in order to get credit. While you are checking lights, it might not be a bad idea to check the dome light as well.

The parking brake will need to be out or engaged to test the parking brake.

The vehicle will need to be stopped with parking brake applied, and the trailer air supply pushed in. Put the vehicle in gear and gently pull against the parking brake with no movement.

Best to make sure you check the handrails, steps, fuel tank, and air tanks at this time.
