Bill > HB4955

This bill modifies the Texas Transportation Code by adding a new provision about high-mounted stoplamps (the third brake light located at the top-center of a vehicle's rear) that clarifies compliance with federal motor vehicle safety standards. Specifically, the bill states that a high-mounted stoplamp will be considered compliant with current federal standards (49 C.F.R. Section 571.108) if it experiences up to four variations in light intensity while braking, as long as the lamp does not completely turn off during a braking period of two seconds or less. This technical amendment provides a precise definition of acceptable performance for vehicle brake lights, potentially giving vehicle manufacturers and owners more clarity about what constitutes a properly functioning high-mounted stoplamp. The bill is set to take effect on September 1, 2025, which gives ample time for stakeholders to understand and implement the new standard.
