The use of a CB radio is no longer subject to any licence or tax. However, it is subject to regulations and standards which vary depending on the country. In general, it is regulated by the government and is limited to certain frequency and emission powers to prevent interference with other radio users and ensure the quality of communication.

At the European level, it is imperative to modulate with a device that meets the essential requirements of the European Directive R & TTE No. 1999 / 5 / EC, according to EN 300433 and/or EN 300135: 4 W PEP 40 channels AM/BLU.

In France, CB radio legislation is defined by Decree No.2000-625 of 5 July, 2000, which provides for the use of the band of frequencies reserved for amateur radio and mobile radio. The transmissions are carried out legally on 40 fixed channels from 26,965 MHz to 27,405 MHz. The use of the CB is authorized without a licence, but CB radio devices must be approved and comply with current standards. CB radio must also be used responsibly and should not be used to transmit messages of a defamatory, racist, violent nature or that affect the dignity of the person. Advertising or commercial messages are also prohibited. Finally, it is recommended to respect the courtesy rules and not monopolize the channel or disrupt communications of other users.

It is therefore important to learn about the rules and regulations in force in each country before using this communication device and to respect these rules to ensure the safe and responsible use of the CB.
