Turn Signals When Towing a Trailer

The arrows on your instrument panel will flash whenever you signal a turn or lane change.

Properly hooked up, the trailer lamps will also flash, telling other drivers you’re about to turn, change lanes or stop.

When towing a trailer, the arrows on your instrument panel will flash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not. It’s important to check occasionally to be sure the trailer bulbs are still working.
