A bunch of California roadway rules changed on January 1, 2026 — but two updates stand out because they can trigger four-figure penalties.
One targets license-plate tricks that defeat toll cameras and plate readers. The other goes after high-tech tools often used in car break-ins.
1) License-plate “obscuring” devices (AB 1085) — up to $1,000
What changed: California tightened rules around products that block the visual or electronic reading of license plates, including items used for toll evasion and to dodge enforcement. California DMV
How the $1,000 hit happens:
- Manufacture or sell a plate-obscuring product/device in California: $1,000 fine per item.
- Operate a vehicle using a prohibited product/device (or alter the plate to defeat capture): $250 fine per violation. Legislative Information
What can get you in trouble (common examples):
- Tinted/shaded plate covers or films
- “Flipper” mechanisms that hide/reveal the plate
- Frames/casings that block characters or interfere with electronic readers
2) Key-programming devices and signal extenders (AB 486) — up to $1,000
What changed: Possessing certain high-tech tools with intent to commit burglary is now explicitly covered, including:
- key programming devices
- key duplicating devices
- signal extenders California Highway Patrol
Why drivers should care: These items are frequently associated with vehicle theft methods, so traffic stops or investigations can surface them…
