1. Frame of any bus, truck, tractor truck is cracked, loose, broken or sagging. Frame of any trailer or semi-trailer has any broken cracked, loose, or sagging top or bottom frame rails or frame is cracked or broken.

2. Engine, transmission or cab mounts, to include all hardware, bolts, and bushings used to connect the mount to the vehicle, frame, engine, or transmission are broken or missing. Any engine or transmission mount shall be rejected if it allows the power train to come in contact with the firewall or other body parts. Cab mounts should be rejected if they do not properly secure the body to the frame.

3. Trailer hitch or pintle hook is not securely attached. Reject if the pintle eye or trailer drawbar has any cracks or if any welding repairs have been made to the pintle eye.

4. Chains, cables, etc., used to attach a towed vehicle are not securely attached, or are broken, worn or abraded.

9. Any cracks, breaks or damaged parts in the stress or load bearing areas of a coupling device.

10. Trailer is not equipped with emergency chain(s) or steel cable(s).

NOTE: Fifth wheel assembly does not require emergency chain or steel cable. A fifth wheel is defined as a device that interfaces with and couples to the upper coupler assembly of a semitrailer. The upper coupler assembly is a structure consisting of an upper coupler plate, king pin and supporting framework which interfaces with and couples to a fifth wheel. Ball and socket connections also referred to as hitch and coupling connections are not fifth wheel assemblies and do require an emergency chain or steel cable.

11. Sliding trailer tandem or multi-axle assemblies do not lock in place or have worn, broken or missing parts.
