What should you do if you're parked and waiting a long time in heavy traffic with your turn signal on to re-enter traffic?

The appropriate action when you're parked and waiting to re-enter traffic while your turn signal is on is to continue waiting and yielding to traffic in the lane. This is the safest approach because it allows you to assess the situation continuously and ensures that you do not interrupt the flow of traffic or create confusion for other drivers.

Maintaining your turn signal indicates to other drivers that you intend to merge, allowing them to adjust their speed or position accordingly. It is essential to remain aware of the traffic around you, ensuring it is safe to merge before proceeding. Patience in heavy traffic is key, as rushing or making sudden movements can lead to accidents or dangerous situations.

While other options might seem convenient, they do not prioritize safety or proper traffic etiquette. For instance, turning off your signal might mislead others about your intentions, while changing lanes immediately could create hazards if other vehicles are still in your blind spot. Turning around and going in the opposite direction does not address the issue at hand and may complicate your route further. Therefore, waiting and yielding is the best and most responsible choice.
