Operating your ham radio while driving is now against the law

Attention California Mobile Operators and Rovers! Recent changes to California Vehicle Code 23123.5 CVC, effective January 1, 2017, regarding use of handheld electronic communication devices, may affect your mobile operation. The code, which previously exempted Amateur Radio, now does not include such language. Amateur Radio operation while driving may now be considered the same as talking on your cell phone and subject to the same restrictions. The California Highway Patrol has reportedly notified the courts that "they intend to issue citations to anyone they see holding a device, which includes your mobile radio microphone."
