Safety and your vehicle
Before towing a trailer, what should you check about its lights?
- Nothing, as a trailer does not need any lights
- Only that the trailer has a number plate fitted
- That its lights and indicators work through the car's electricsCorrect
- That the trailer lights are a different colour from the car's
Why?
A trailer's rear lights, brake lights and indicators connect to the car through the towbar electrics, and other drivers rely on them to read your signals. Annex 6 of The Highway Code says lights and indicators must work, so plug in and test them before you set off.
