After windshield replacement or front camera repairs, drivers may notice that road sign information is no longer displaying correctly. This is often due to the need for Traffic Sign Recognition Calibration, which ensures the camera system accurately reads and interprets speed limits and road signs. Without proper calibration, the vehicle may show incorrect or missing sign data, which can affect driving decisions and safety. A certified technician uses specialized tools to realign and reset the system according to manufacturer guidelines. Once completed, the system can reliably detect traffic signs, helping drivers stay informed, follow road rules, and improve overall driving safety.
