When must a driver use turn signals in Texas?

Using turn signals is a crucial aspect of safe driving as it communicates a driver's intentions to other road users. In Texas, the law requires drivers to signal at least 100 feet before making a turn or changing lanes. This distance allows other drivers, pedestrians, and cyclists ample time to react to the driver's intended movement. Signaling too late could increase the risk of accidents, as other road users may not anticipate the turn or lane change.

The requirement to signal in advance is part of promoting road safety and ensuring smooth traffic flow. By indicating their intentions early, drivers help maintain awareness and cooperation on the road, reducing confusion and potential conflicts.

While there are other contexts in which turn signals might be used, such as when changing lanes or in residential areas, the law specifically mandates the 100-foot rule to cover all scenarios of making turns or lane changes. This ensures a standard practice that enhances safety for everyone on the road.
