Trailer safety check before towing

Before you hitch up, do a walk-around: check that the trailer hitch is locked tight, safety chains are crossed and snug, and the coupler is secure. Verify that tire pressure and lights work, including brake and turn signals. Don't forget to test the breakaway cable and ensure the load is balanced and tied down. A few minutes of inspection can prevent a serious accident on the road.
