What is the required distance to signal a lane change in Texas?

In Texas, the law requires drivers to signal their intention to change lanes at least 100 feet before making the maneuver. This distance allows other drivers ample time to notice the signal and react safely, which is important for maintaining safe driving conditions. Signaling in advance helps to prevent potential accidents by making your intentions clear, thereby allowing other road users to adjust their speed or position accordingly.

While the other options suggest shorter or longer distances, only the 100-foot requirement balances the need for clarity with the practicality of real-world driving situations. Signaling too early or too late may reduce the effectiveness of the signal, potentially leading to confusion or unsafe driving environments. Therefore, signaling at least 100 feet in advance is a critical component of safe driving practices in Texas.
