An Act amending Title 75 (Vehicles) of the Pennsylvania Consolidated Statutes, in rules of the road in general, further providing for prohibiting use of hearing impairment devices.

HB 646 amends Pennsylvania's vehicle code to prohibit drivers from using hearing impairment devices, such as hearing aids or cochlear implants, while operating a motor vehicle. This law directly affects drivers who rely on such devices, making it illegal to use them while driving. The key provision updates the "rules of the road" under Title 75 to explicitly ban the use of these devices behind the wheel. The bill became law as Act No. 43 of 2025 after receiving gubernatorial approval on November 6, 2025.
