Thibaut (HB 1258) Act No. 439 Existing law requires that all law enforcement agencies involved in traffic enforcement establish guidelines for the operation of seat belt checkpoints and proof of compulsory motor vehicle liability security checkpoints. New law adds motor vehicle inspection checkpoints to existing law. Existing law provides that checkpoint guidelines include location, time, and duration, and they shall be established in written form by supervisory or administrative personnel rather than field officers. New law provides that the location of a motor vehicle inspection checkpoint cannot be less than 500 feet from an intersection between a state and federal highway. Effective Aug. 1, 2014.
