If you haven’t checked your state’s traffic laws lately, 2026 is the year to start. Across the country, and especially in California, legislators have passed a wave of new driving laws that tighten impaired driving penalties, expand protections for roadside workers, crack down on distracted driving, and give car buyers new tools against shady dealership practices.
Here’s what’s changing and what it means for you behind the wheel.
Tougher DUI Rules and Ignition Interlock Expansion
California’s ignition interlock requirements just got broader. Under Assembly Bill 366, which took effect January 1, 2026, the state’s Statewide Ignition Interlock Device (IID) program now covers a wider pool of DUI offenders, including certain first-time offenders who previously would not have been required to install the device.
An IID requires a driver to blow into a breathalyzer before the car will start. If alcohol is detected, the engine stays off. The idea is to keep offenders on the road legally, under supervision, rather than simply revoking their licenses and hoping they don’t drive anyway.
A related measure, Senate Bill 720, reinforces that approach by shifting away from automatic license revocation for some DUI convictions. Instead, driving privileges are tied to compliance with IID requirements and other court-ordered conditions. The California courts’ own summary of 2026 traffic law changes describes this as a move toward technology-based monitoring over blanket suspensions.
California is not alone. According to Mercury Insurance’s analysis of 2026 driving laws, tougher DUI treatment for high-risk drivers is one of several factors putting upward pressure on auto insurance premiums nationwide. States including Colorado, Virginia, and Texas have also expanded or strengthened their own interlock programs in recent legislative sessions.
“Slow Down, Move Over” Laws Now Cover More Vehicles
Most drivers know to change lanes for a police car on the shoulder. Fewer realize the same duty has applied to tow trucks, Caltrans vehicles, and other emergency responders for years. Starting in 2026, California’s “Slow Down, Move Over” law covers significantly more situations.
Assembly Bill 390 expands the requirement to include any stationary vehicle displaying emergency or warning lights on a highway, not just traditional emergency responders. That means a utility truck with amber flashers, a disabled car with its hazards on, or a highway maintenance crew all now trigger the same obligation: move over a lane if you safely can, or slow down significantly if you can’t.
The California Highway Patrol flagged AB 390 as one of the most important public safety laws taking effect this year. Legal analysts at Aitken Aitken Cohn note that the expansion also increases liability exposure: if you strike someone near a stopped vehicle with flashing lights, the fact that you failed to slow down or move over can be used against you in court.
The practical rule of thumb is simple. If you see flashing lights on the shoulder or in a lane ahead, treat it as a “move over” situation regardless of the vehicle type. The fine for a violation can reach several hundred dollars, and the consequences of a collision are far worse.
Stricter Distracted Driving Enforcement and Automated Speed Cameras
Hands-free driving laws have been on the books in dozens of states for years, but 2026 marks a turning point in how aggressively they’re enforced. Grace periods that gave drivers warnings instead of tickets have expired in several states, and police departments are now issuing citations for any handheld phone use, including holding a phone at a red light.
The bigger shift is technological. California is expanding automated speed enforcement through pilot programs authorized under Assembly Bill 645, which originally launched camera-based speed detection in select cities in 2024. As of 2026, additional cities, including Malibu, are joining the program, and local agencies have broader authority to deploy cameras at intersections and corridors with high crash rates.
These cameras don’t just catch speeders. The data they generate feeds into traffic safety analyses that can lead to lower posted speed limits, redesigned intersections, and targeted enforcement campaigns. For drivers, the takeaway is straightforward: automated systems don’t take breaks, don’t exercise discretion, and don’t forget to write the ticket.
Nationally, the trend is similar. Several states have introduced or expanded automated enforcement tools in 2026, and the National Highway Traffic Safety Administration has signaled support for technology-assisted speed management as part of its long-term safety strategy.
Stronger Consumer Protections in Car Sales and Vehicle Tech
The changes aren’t limited to what happens on the road. California is also overhauling how cars are sold.
The centerpiece is the CARS Act, a state-level consumer protection law that prohibits dealers from misrepresenting key facts during a vehicle sale, including the condition of the car, its pricing, and any add-on products or fees. The law targets so-called “junk fees,” those line items for paint protection, VIN etching, or nitrogen-filled tires that appear on the final bill without a clear explanation or the buyer’s informed consent.
Under the CARS Act, dealers who misrepresent a vehicle or slip in unwanted extras face civil penalties. For shoppers, this means stronger legal footing if a dealer inflates the price of a used SUV with undisclosed add-ons or misrepresents the history of a certified pre-owned sedan.
On the technology side, a law that took effect in 2025 is gaining new relevance as connected car features become standard. Senate Bill 1394, authored by Senator Dave Min, requires vehicle manufacturers to let drivers terminate remote access to their car if they suspect the tracking or connected-service features are being misused. The law also limits how long manufacturers can retain or share location data and requires disclosure when third parties have accessed a vehicle’s features or location.
The law was driven in part by concerns about domestic abuse and stalking. Connected car systems can reveal a driver’s real-time location, travel history, and even whether the doors are locked. For someone fleeing an abusive partner, the ability to cut off that access quickly is not a convenience; it’s a safety measure.
What’s Ahead for Autonomous and Emerging Vehicles
California and several other states are also updating their frameworks for autonomous vehicles and advanced driver-assistance systems in 2026, though the regulatory picture remains fragmented. The California Department of Motor Vehicles continues to issue and revise permits for companies testing self-driving vehicles on public roads, and the National Highway Traffic Safety Administration is expected to finalize updated guidance on how automakers must report crashes involving automated driving systems.
For most drivers, the immediate impact is limited. But the regulatory groundwork being laid now will shape how quickly fully autonomous vehicles move from controlled pilots to everyday roads, and what insurance, liability, and safety standards will apply when they do.
The Bottom Line for Drivers in 2026
The common thread across all of these changes is accountability. Legislators and regulators are betting that a combination of tougher penalties, expanded technology, and clearer consumer rights will reduce crashes, protect vulnerable roadside workers, and curb abuses in the car market.
For drivers, the checklist is short but worth reviewing: know your state’s updated DUI and interlock rules, treat any vehicle with flashing lights as a “move over” situation, keep your phone out of your hands, watch for speed cameras in pilot zones, and read every line of your next car purchase agreement.
None of these laws are optional, and as of spring 2026, most are already in effect.
