Here's an exerpt of the law I alledgely broke, and yup, it does say "Properly":
27315. (a) The Legislature finds that a mandatory seatbelt law will contribute to reducing highway deaths and injuries by encouraging greater usage of existing manual seatbelts, that automatic crash protection systems which require no action by vehicle occupants offer the best hope of reducing deaths and injuries, and that encouraging the use of manual safety belts is only a partial remedy for addressing this major cause of death and injury. The Legislature declares that the enactment of this section is intended to be compatible with support for federal safety standards requiring automatic crash protection systems and should not be used in any manner to rescind federal requirements for installation of automatic restraints in new cars.
(b) This section shall be known and may be cited as the Motor Vehicle Safety Act.
(c) (1) As used in this section, "motor vehicle" means any passenger vehicle or any motortruck or truck tractor, but does not include a motorcycle.
(2) Until May 1, 2000, for purposes of this section, a "motor vehicle" also means any farm labor vehicle that was first issued an inspection certificate under Section 31401 on or after October 1, 1999.
(3) On and after May 1, 2000, for purposes of this section, a "motor vehicle" also means any farm labor vehicle, regardless of date of certification under Section 31401.
(d) (1) ( )1 A person may not operate a motor vehicle on a highway unless that person and all passengers 16 years of age or over are properly restrained by a safety belt. This paragraph does not apply to the operator of a taxicab, as defined in Section 27908, when the taxicab is driven on a city street and is engaged in the transportation of a fare-paying passenger. The safety belt requirement established by this paragraph is the minimum safety standard applicable to employees being transported in a motor vehicle. This paragraph does not preempt any more stringent or restrictive standards imposed by the Labor Code or any other state or federal regulation regarding the transportation of employees in a motor vehicle.
