The expanded "Slow Down, Move Over" law creates new challenges for CDL holders on I-80 near Roseville, CA.
Under Assembly Bill (AB) 390, you must now move over for all stationary vehicles. This amendment applies to any disabled vehicle along I-80 displaying hazard lights or warning devices.
“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.”— AB-390, Wilson. Vehicles: Highway Safety.
This new law could create a double hazard for commercial drivers who are required to use the right-hand lane for travel and the second lane only for passing. Most commercial vehicles are prohibited from using the third lane or beyond.
Understanding the AB 390 Expansion on I-80
Previously, this law mainly protected emergency vehicles and tow trucks with flashing lights.
Starting in 2026, the CHP enforces this rule for every vehicle on the shoulder. Whether it is a delivery van or a stranded motorist, you must give them space.
This change aims to reduce the rising number of roadside fatalities in Placer County and across California.
What to Do During a Roadside Stop
If you see a vehicle with hazards on I-80, you must act immediately.
You are required to move into an available lane that is not adjacent to them. If changing lanes is unsafe, you must slow to a reasonable and prudent speed.
Failure to follow these steps can lead to a costly commercial traffic ticket.
Consequences of a Move Over Violation for Your CDL
A violation of AB 390 is a moving violation that can harm your driving record in California and your PSP at the DOT FMCSA level.
For commercial drivers, violations can be assessed against them both at the federal and state level. The new vehicle code violation is a moving violation that will remain on the driver’s PSP for up to three years, and count against the carrier’s SMS percentile for two.
Why a Clean PSP Matters
A paid fine for this violation leads to CA DMV NOTS points and possibly FMCSA notification.
Your carrier will see CSA severity points time-weight multiples that stay on their record for two years. This conviction also leaves a scar on your PSP for up to 36 months, which impacts your future employment potential.
We help you fight these CDL tickets to keep your career moving forward. Plus, a clean record means the driver can negotiate higher pay and better benefits.
