Please make sure that you point at or touch both tanks to insure you receive credit for them, and they both need checked for security, bands and grommets, the lines between tanks, and leaks.
3 / 20
A. False
B. True
This is true, on each side of the vehicle you need to check the light lenses and reflectors, and you should get credit for both the tractor and the trailer if you tell the examiner you would check both at this time. The lenses and reflectors need to be mounted, clean, and not damaged or missing.

D. The connection at the tractor, the lines for breaks cracks frays, the connection to the trailer, and that none of these are leaking
Make sure to check the connection at the tractor, the lines for breaks cracks frays, the connection to the trailer, and that none of these are leaking. Group them together at the tractor, between the vehicle, and at the trailer to make this part go quickly.
5 / 20
A. Frame, catwalk, exhaust, and cab mounts
B. Frame, catwalk, and exhaust
C. Frame, catwalk, exhaust, cab mounts, and driveshaft
D. Frame, catwalk, exhaust, and driveshaft
Frame needs checked for cracks, bends, illegal welds, that it is secure, and mounting bolts. Catwalk needs to be in good condition with all mounting bolts in place. Exhaust needs to be secure; all pipes and connections need to be secure and free of leaks. The driveshaft needs to be properly mounted, tight sand secure, u-joints in good condition and move freely, and there is no excessive play.

A. That it is not bent, damaged, or cracked, has no illegal welds, and that it is securely mounted
B. That it is not bent, damaged, cracked, and that it is securely mounted
C. That it is not bent, and that it is securely mounted
D. That it is not bent, damaged, or cracked
The apron itself should not be bent, cracked, or damaged. It will be welded to the bottom of the trailer, but it should not have welds on the surface that the 5th wheel contacts, and it should be securely mounted.

9 / 20
A. True
B. False
This is true. The 5th wheel tilts so that the coupling can withstand unlevel surfaces, it cannot have welds or cracks, and needs to be secure.
10 / 20
A. True
B. False
This is true. The kingpin needs to be completely extended and around the shank of the kingpin.
11 / 20
A. False
B. True
To have a properly connected vehicle there can be no gap between the 5th wheel and the apron. If there is a gap you should disconnect the tractor, lower the front of trailer, and recouple the tractor. A gap could mean the locking jaws went around the head of the kingpin instead of the shank. This is dangerous because a large bump may cause the trailer to lift, and the kingpin to slide out of the locking jaws.
12 / 20
A. completely in with the locking mechanism released
B. completely out with the locking mechanism secured
C. completely out with the locking mechanism released
D. completely in with the locking mechanism secured
The release arm needs to be pushed completely in with the locking mechanism secured. You want to make sure this is secure because if it is not the trailer might break free of the locking jaws.
