Move Over Laws by State
Every state has a move-over law, but they do not all protect the same people — some cover only emergency vehicles, others now cover every stopped car with its hazards on. Pick your state to see what you must do, how much you must slow down, and what a first ticket costs. Checked against each state’s own statute in November 2026.
General information only, not legal advice. Duties and penalties checked against each state’s statute — or its official fine schedule where the statute sets no dollar amount — in November 2026. Court costs and fees are extra unless the figure shown already includes them. Never brake suddenly or stop in a travel lane to comply; slow smoothly and move over only when it is safe.
One duty, fifty-one versions
Underneath the differences, every one of these laws asks for the same two moves: take the far lane when you safely can, and slow down when you cannot. Where the 51 versions split is who they protect — a shrinking group of states still covers only emergency and road-service vehicles, while the rest now cover every stopped vehicle showing hazard lights — and how the slow-down is measured: fixed formulas in states like Florida, Michigan and West Virginia, a “reasonable and prudent” speed in others. The lookup above gives your state’s exact version, taken from its own statute.
The habit that satisfies every version
Scan the shoulder early, ease off the accelerator, and take the far lane when a safe gap allows. When it does not, slow smoothly to well under the limit and stay slow until you are completely past. That single habit complies with all 51 laws, including the strictest — and it is the habit that gets troopers, tow crews and stranded families home.
Move over law questions, answered
What exactly is a move-over law?
Every state, and the District of Columbia, requires drivers approaching a covered vehicle stopped at the roadside to give it room: change into a lane that is not next to it when that can be done safely, and slow down — in some states whether or not the lane change was possible. The laws exist because the shoulder is one of the most dangerous workplaces in America: officers, tow operators, road crews and stranded motorists are regularly killed by passing traffic.
Do I have to move over for a broken-down car, or only for police?
It depends on your state. Around thirty states now extend the duty to every stopped vehicle displaying hazard lights or other warning signals — Arizona, California, Colorado, Kansas, Maryland and Wisconsin among the most recent. Others still protect only emergency and road-service vehicles: Texas, for example, has a closed list of eight vehicle categories, and Illinois covers emergency vehicles but not ordinary disabled cars. Use the lookup above for your state rather than guessing.
What if traffic makes it impossible to change lanes?
Then the slow-down half of the law applies. Some states set a fixed formula — 20 mph below the posted limit is the most common, and Michigan requires 10 mph below even when you do change lanes — while others require a “reasonable and prudent” speed for the conditions. What no state wants is a sudden stop in a travel lane: slow smoothly, pass wide if you can, and never brake hard in front of following traffic to comply.
How much is a move-over ticket?
Anywhere from $20 — North Dakota’s fine for its stationary-vehicle duty — to a flat $1,000 for a first offense in Oklahoma. Most states add court costs on top of the figure in the lookup, many add license points, and a few treat the violation as a crime rather than a ticket: it is a Class A misdemeanor in Missouri and reckless driving in Virginia when the vehicle beside you is an emergency vehicle. Causing an injury or a death raises the penalty sharply everywhere.
Does the law apply on two-lane roads?
Yes. On a road with no spare lane, the slow-down duty is the whole law. Some states set exact caps for this case: West Virginia requires no more than 15 mph on a nondivided highway and 25 mph on a divided one, and South Dakota requires you to be at least 20 mph below the limit starting 300 feet before the stopped vehicle.
Why have so many states expanded these laws recently?
Because roadside deaths kept climbing, legislatures spent 2023–2026 widening the laws from emergency vehicles to every stopped vehicle. Colorado, Maryland and North Dakota expanded in 2022–23; South Dakota, West Virginia, New Hampshire and Nebraska followed in 2025; California’s all-vehicles rule took effect on January 1, 2026, and Wisconsin’s in December 2025. The direction of travel is one-way: if your state does not cover disabled vehicles yet, it probably soon will.
