When must you give a signal for lane changes?

You must give a signal for lane changes any time you change lanes because signaling is a critical safety measure that communicates your intentions to other drivers. This practice allows other road users to anticipate your movements, thereby reducing the risk of collisions. Proper signaling helps maintain a safe and organized flow of traffic, ensuring that everyone on the road can react appropriately to your actions.

In Texas, as well as in most jurisdictions, it is mandated by law to signal when changing lanes, regardless of the time of day, the impact on other traffic at that moment, or the type of vehicle you are operating. This consistent practice fosters safer driving habits and encourages mutual respect among drivers on the road.
