KESQ reported in February 2026 that California's Slow Down, Move Over law had expanded to require drivers to slow down and change lanes for any stationary vehicle displaying hazard lights or warning devices such as cones, flares, or reflective triangle markers, according to KESQ. The on-the-ground reporting walked drivers through how the new duty applies to everyday roadside scenes.
Operator takeaway
Cone, flare, and reflective triangle markers now trigger the Move Over duty in California. Make sure your truck's standard scene-setup kit reflects what the law now treats as a legal trigger for passing drivers.
