Pre-trip trailer safety inspection
https://smart-wiki.win/index.php/Pre-trip_trailer_safety_inspection
Before hitting the road, I always do a quick walk-around of my trailer. I check the hitch is locked tight, the safety chains are crossed and connected, and the breakaway cable is attached to the truck. Then I verify all lights work—turn signals, brakes, and tail lights. I give the tires a look for proper inflation and any damage, and I make sure the wheel chocks and jack are secure. It only takes a few minutes, but it’s saved me from serious trouble more than once.
