Oklahoma's Move Over Law and Roadside Crash Claims

Oklahoma's Move Over Law requires every driver who approaches a stopped vehicle displaying flashing lights — an emergency vehicle, a highway maintenance truck, a licensed wrecker, or simply another motorist stopped with hazard lights on — to change into a lane that is not next to the stopped vehicle when it is possible and safe to do so, and otherwise to slow to a safe speed and proceed with due caution. The rule lives at 47 O.S. § 11-314, which Oklahoma has called Bernardo's Law since 2021 and the Bernardo-Mills Law since November 1, 2023 — the date the Legislature first attached real fines to it. If you or a family member was hit while stopped on the shoulder — changing a tire, waiting for a tow, or working a roadside job — the statute matters twice: once as the traffic rule the passing driver may have broken, and again as part of the civil fault analysis.

This article is general legal information, not legal advice about any specific crash. Whether the Move Over Law applies, and what a violation means for a claim, depends on facts that need individual review.

What the Law Requires

Section 11-314 splits the duty by road type. On a highway with two or more lanes running the same direction, the approaching driver must proceed with due caution and, "if possible and with due regard to the road, weather, and traffic conditions," change into a lane that is not adjacent to the stopped vehicle. If the driver cannot change lanes safely, the fallback duty applies: proceed with due caution and reduce speed to a safe speed. On any other road — including the two-lane state highways that connect most Oklahoma towns — the duty is to slow to a safe speed and proceed with due caution.

The statute lists who is protected. It covers a stationary authorized emergency vehicle, a Department of Transportation maintenance vehicle, a Turnpike Authority maintenance vehicle, a licensed wrecker displaying flashing amber, red, or blue lights in any combination — and, in the catchall that surprises many drivers, "a stationary vehicle that is displaying flashing lights." According to the Oklahoma Department of Transportation, that language came from Senate Bill 89 in 2019, which extended the safety-zone law to any vehicle with flashing lights, including a civilian car with its hazards on, effective November 1, 2019.

In plain terms: the family stopped on the I-35 shoulder with a blown tire and hazard lights flashing is inside the statute's protection, just like the trooper working a crash scene.

The Bernardo-Mills Law: What Changed in 2023

The section already had a name before 2023: Bernardo's Law, given to it by the Legislature in 2021. What House Bill 2684 added, effective November 1, 2023, was a second name and — for the first time — real money. Before that amendment, § 11-314 stated the duty but carried no fine schedule of its own. The bill's House author said the added name honors John Mills, a tow truck operator killed while working along U.S. Highway 69, according to Capitol Beat OK.

Under the current statute, a driver who violates the move-over duty commits the offense of endangerment of an emergency worker. When no emergency worker is injured or killed, the fine is a flat $1,000 for a first offense and $2,500 for a second. When the violation injures an emergency worker, the offense becomes aggravated endangerment, with a fine of up to $5,000 — and up to $10,000 if an emergency worker is killed, in addition to any other penalty authorized by law.

Two things here are worth knowing. First, the enhanced fines turn on injury or death of an "emergency worker," but neither § 11-314 nor Title 47's definitions define that term. The duty in subsection B plainly runs to an ordinary car stopped with its hazards on. Whether the person standing beside that car is an "emergency worker" for purposes of the $5,000 and $10,000 fines is an open question, and it is the kind of gap a prosecutor and a defense lawyer will read in opposite directions.

Second, the statute contains an escape hatch — but only on the ticket side. Under subsection F, a driver cannot be cited or convicted of endangerment if the violation resulted, in whole or in part, from mechanical failure of the driver's own vehicle or from the negligence of another person or an emergency worker. That provision decides whether a traffic charge sticks. It does not decide who pays for an injury. Civil fault is a separate question under ordinary negligence and comparative-fault rules.

Why the Statute Matters in an Injury Claim

A traffic citation is not a lawsuit, and a fine paid to the court does not compensate the person lying in a hospital bed. But a statutory violation can do heavy lifting in a civil negligence case through the doctrine of negligence per se.

The Oklahoma Supreme Court explained the doctrine in Howard v. Zimmer, Inc., 2013 OK 17, an answer to a certified question from the Tenth Circuit in which the court held — in the injured plaintiff's favor — that Oklahoma law permitted a negligence per se claim built on a federal regulation. Along the way, the court restated the elements: negligence per se substitutes a statutory standard for the common-law duty of reasonable care, and it applies when the claimed injury was caused by the violation, the injury is of the type the statute was intended to prevent, and the injured person is one of the class the statute was intended to protect.

A person struck while stopped on the shoulder with flashing lights is squarely inside what § 11-314 exists to prevent. Two cautions, though. Oklahoma courts decide for themselves whether a statute is a fit standard for civil liability, and the Court of Civil Appeals has held that a negligence per se instruction is not appropriate where a statute's terms do not impose positive, objective standards. Chartney v. City of Choctaw, 2019 OK CIV APP 26. That matters here because § 11-314 contains two different duties. The command to change lanes is concrete and objective. The fallback — proceed with due caution and reduce speed to a safe speed — reads a great deal like the ordinary reasonable-care standard, and a defendant will say so. We are also not aware of a published Oklahoma appellate decision applying negligence per se to § 11-314 in either direction. This is a question for your lawyer to evaluate early because the answer shapes what the jury is told about the passing driver's duty.

Even without negligence per se, the statute frames the fault story. Oklahoma juries decide comparative fault, and a defendant who ignored a duty the Legislature spelled out — move over or slow down — starts that conversation in a deep hole. Our explainer on the Oklahoma 51% bar covers how fault percentages control who can recover and how much.

If You Were the One Stopped on the Shoulder

Expect the passing driver's insurer to argue that the stopped person contributed to the crash — stopped too close to the travel lane, no flashers, walked into the roadway. Some of those arguments have force in some cases; many do not. A few points to keep in view:

• Hazard lights matter. Since the 2019 amendment, flashing lights are what trigger the approaching driver's statutory duty toward an ordinary stopped car. Evidence that your flashers were on — witness statements, dashcam footage, vehicle data — is worth preserving immediately.
• Subsection C is not aimed at an ordinary stranded driver. It says only that the move-over duty does not excuse the operator of a stopped emergency, maintenance, or wrecker vehicle "from the consequences of reckless disregard for the safety of all persons and property upon the highway." If you were in your own car with the hazards on, that provision is not about you. If you were working a wrecker or a maintenance truck, your own conduct can still be considered.
• Commercial trucks that stop on the highway have their own federal warning-device duties, which we cover in our article on stopped trucks and warning devices. In a car-versus-truck shoulder crash, both sets of rules can be in play at once.

Roadside crashes also tend to be severe, because the stopped person is often outside the vehicle — standing at a jack, loading a wrecker, or flagging traffic — with no steel around them. Injury documentation, scene photographs, and early witness identification matter more than in a typical fender case, and they disappear fast.

What to Do After a Shoulder or Roadside Crash

The first steps look like any serious wreck: get medical care, report the crash, and preserve what you can. The move-over angle adds a few specific items worth raising with a lawyer early — whether the investigating officer cited the passing driver under § 11-314, whether nearby cameras or dashcams captured your flashing lights, and whether the passing driver had room to change lanes. Traffic and lane-position evidence is exactly the kind of proof that vanishes when vehicles are repaired and camera footage cycles.

Frequently Asked Questions

Does Oklahoma's Move Over Law apply to ordinary cars with hazard lights on?

Yes. Since November 1, 2019, the statute has covered any "stationary vehicle that is displaying flashing lights," not just emergency vehicles, maintenance trucks, and wreckers. A driver approaching a civilian car stopped with hazards flashing must change to a non-adjacent lane when it is safe and possible, or slow to a safe speed.

What if I could not change lanes when I passed a stopped vehicle?

The statute builds in the answer: the lane change is required "if possible and with due regard to the road, weather, and traffic conditions." A driver who cannot change lanes safely must instead proceed with due caution and reduce speed to a safe speed. Doing neither is what violates the law.

What are the fines for violating the Move Over Law?

Under the fine schedule House Bill 2684 added effective November 1, 2023, the fine is a flat $1,000 for a first offense and $2,500 for a second when no emergency worker is injured or killed. If the violation injures an emergency worker, the fine rises to as much as $5,000; if an emergency worker is killed, as much as $10,000, in addition to any other penalty authorized by law.

Can a Move Over Law violation help my injury case?

It can. Oklahoma's negligence per se doctrine may allow a statutory violation to establish breach of duty when the statute supplies a suitable civil standard, the violation caused the injury, the injury is the type the statute was designed to prevent, and the injured person is in the protected class. Even if a court declines to treat § 11-314 as a negligence per se standard, the underlying conduct — passing a stopped vehicle with flashing lights without moving over or slowing down — is still conduct a jury can weigh under ordinary negligence. How the doctrine applies to a specific crash is a question for your lawyer.

Why did Oklahoma add Mills to the Move Over Law's name?

The bill's House author said the 2023 amendment added the name of John Mills, a tow truck operator killed while working along U.S. Highway 69. The Legislature had already called the section Bernardo's Law since 2021. The updated name reflects the people the statute most visibly protects: tow operators, first responders, and road workers who do their jobs a few feet from live traffic.
