Possession and use of radar detection devices prohibited.
(a) No person shall operate or be in actual physical control of a
commercial motor vehicle as defined in Section 6-500(6) of this Code while
the motor vehicle is equipped with any instrument designed to detect the
presence of police radar for the purpose of monitoring vehicular speed.
(b) Notwithstanding subsection (a) of this Section, a person operating a
commercial motor vehicle as defined in Section 6-500(6) of this Code, who
possesses within the vehicle a radar detecting device that is contained in
a locked opaque box or similar container, or that is not in the passenger
compartment of the vehicle, and that is not in operation, shall not be in
violation of subsection (a) of this Section.
Any person found guilty of violating this Section shall be guilty of a
petty offense. A minimum fine of $50 shall be imposed for a first offense
and a minimum fine of $100 for a second or subsequent offense.
(c) The radar detection device or mechanism shall be seized by the law
enforcement officer at the time of the violation if the offender has

radar detection device or mechanism. Any such device or mechanism shall be
taken and held for the period when needed as evidence. When no longer
needed for evidence, the defendant may petition the court for the return of
the device or mechanism; provided the defendant shall prove to the court by
a preponderance of the evidence that the device or mechanism will be used
only for a legitimate and lawful purpose.
(d) No commercial motor vehicle, or driver of such vehicle, shall be
stopped or searched by any law enforcement officer solely on the basis of a
violation or suspected violation of this Section.
