From today's ARRL Letter:
* Amateur Radio Exempt from California's New "Hands Free" Law: On July 1, the State of California will have new laws on the books to deal with the use of wireless telephones while driving. There has been some confusion as to whether California amateurs who operate in their car will be affected by the new law. According to the California Department of Motor Vehicle's Web site http://www.dmv.ca.gov/cellularphonelaws/dl208_03cell_phone.pdf, "the use of dedicated two-way radios such as walkie-talkies or Citizen Band (CB) radios is not affected by the new law" for drivers 18 or older.
