There aren't any laws prohibiting installation of CB radios in vehicles, and you don't need a special license to operate a CB station. CB radio rules are under the jurisdiction of the FCC.
A CB radio is a wireless transceiver that operates on the frequency band called Citizen Band, CB. This band has been reserved for the public. In some countries license is required and in some countries no license is required to operate CB radio. The maximum power limit is 5 Watts. There are 40 channels around 27 MHz in this band.
(In the United States) you do not need a license to own a HAM radio. You may Listen to communications on a HAM radio without a license. However, you may NOT transmit on a HAM radio without a license.

No. See http://wireless.fcc.gov/services/index.htm?job=service_home&id=cb, which says "License documents are neither needed nor issued and there are no age or citizenship requirements. As long as you use only an unmodified FCC certificated CB unit, you are provided authority to operate a CB unit in places where the FCC regulates radio communications."
