What should you use if your vehicle's directional signals fail?

When your vehicle's directional signals fail, it is important to communicate your intentions to other drivers in a clear and effective manner to ensure everyone's safety on the road. Hand signals provide a reliable method of indicating turns or lane changes when electronic signals are not functioning.

Using hand signals enables you to alert other drivers to your intended actions, similar to what a directional signal would do, thus helping to prevent accidents. The specific hand signals include extending your left arm straight out for a left turn, bending it upward for a right turn, and bending it downward to signal a stop.

While emergency flashers can indicate to others that there is an issue with your vehicle or that you are stopped, they do not effectively communicate your specific intentions for turning or changing lanes. Therefore, hand signals are the most appropriate and visible method for communicating during such circumstances.
