What the shift check covers
The standard names the parts. Check that each is there, working, and undamaged:
- Service brakes, including trailer brake connections.
- Parking (hand) brake and the emergency stopping/braking system.
- Tires — inflation, tread, cuts, and no missing lugs.
- Horn.
- Steering mechanism.
- Coupling devices — hitch, pintle, fifth wheel, safety chains.
- Seat belts.
- Operating controls and all safety devices (lights, wipers, alarms, mirrors).
Add fluids, leaks, and mirror/glass condition to the loop — anything that would stop you seeing or stopping.
