AB 390: Vehicles: highway safety.

Official summary

Legislative Counsel’s Digest (official, as of the latest version). Written by nonpartisan legislative staff; reproduced verbatim.

Existing law requires a driver approaching, among others, a stationary marked Caltrans vehicle that is displaying flashing lights to approach with due caution and either change lanes to a lane not immediately adjacent to the vehicle, or, if unable to safely do so, slow to a reasonable and prudent speed, as specified. Existing law makes a violation of that provision an infraction, punishable by a fine of not more than $50.

This bill would expand that requirement to apply to all marked highway maintenance vehicles, as defined, and would also make that requirement applicable to any other stationary vehicle displaying flashing hazard lights or another warning device, including, but not limited to, cones, flares, or retroreflective devices. By expanding the scope of a crime, this bill would impose a state-mandated local program.

The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.

This bill would provide that no reimbursement is required by this act for a specified reason.
