Texas Move Over / Slow Down Law 2026: §545.157 Fines & What You Must Do for Emergency Vehicles

The Texas Move Over / Slow Down Law: Saving Lives on the Roadside

Every year, emergency responders, tow truck operators, highway maintenance workers, and stranded motorists are killed or seriously injured on Texas roadsides because passing drivers failed to move over or slow down. The Texas Move Over / Slow Down law — codified in Transportation Code §545.157 — exists to protect these vulnerable individuals.

Despite being on the books for over two decades, this law remains one of the most frequently violated — and least understood — traffic regulations in Texas. Many drivers are unaware of the specific requirements, which vehicles are covered, or the severe penalties for non-compliance.

This 2026 guide covers everything you need to know: the exact legal requirements, which vehicles trigger the obligation, the penalty structure, enforcement methods, and practical tips for compliance.

What the Law Requires: Your Two Options

When you approach a stopped vehicle displaying flashing warning lights (red, blue, amber, or a combination) on the shoulder or roadside, you must take one of two actions:

Option 1: Move Over

• Vacate the lane closest to the stopped vehicle by changing to an adjacent lane
• This applies to multi-lane roads (highways, interstates, and roads with two or more lanes in your direction of travel)
• You must move over only if it is safe to do so — if traffic conditions prevent a safe lane change, you must use Option 2 instead

Option 2: Slow Down

• Reduce your speed to 20 mph below the posted speed limit
• On roads with a posted speed limit of 25 mph or less, reduce to 5 mph
• Maintain the reduced speed until you have completely passed the stopped vehicle

Both Options May Apply

On multi-lane roads, the safest approach is to both move over AND slow down. The law requires at minimum one of the two actions, but combining them provides the greatest margin of safety for roadside personnel.

Which Vehicles Are Covered?

The Move Over / Slow Down law has been expanded significantly over the years to cover a wide range of vehicles beyond just police and fire. As of 2026, the following vehicles trigger the obligation when stopped and displaying flashing lights:

Key expansion: The 2023 legislative session expanded the law to include any stationary vehicle displaying hazard lights or flashing warning lights on the roadside. This means the move over or slow down obligation now applies even to a regular passenger car with its hazard lights on — not just marked emergency and service vehicles.

Penalty Structure: Fines and Jail Time

The penalties for violating the Move Over / Slow Down law escalate based on the consequences of the violation:

Total Cost Beyond the Fine

As with other traffic violations, the courtroom fine is only the beginning:

How the Move Over Law Is Enforced

Texas law enforcement uses several methods to enforce the Move Over / Slow Down law:

Direct Officer Observation

The most common enforcement method. When officers are conducting a traffic stop, working an accident scene, or assisting a stranded motorist, they observe passing traffic and can note vehicles that fail to move over or slow down. A second officer may be positioned nearby specifically to cite violators, or the original officer may note the license plate and issue a citation later.

Dedicated Enforcement Operations

DPS and local agencies periodically conduct targeted Move Over enforcement operations:

• A marked patrol vehicle is parked on the shoulder with its lights activated (often with a mannequin or an actual officer standing nearby)
• Spotters upstream identify vehicles that fail to move over or slow down
• Officers downstream stop and cite the violators
• These operations are common during National Move Over Day (typically in October) and during awareness campaigns throughout the year

Dashcam and In-Car Video

Many emergency vehicles and tow trucks are equipped with dashcams and rear-facing cameras that capture approaching traffic. This footage can be used as evidence to support Move Over violations, even if the driver is not pulled over immediately.

TxDOT Awareness Campaigns

TxDOT runs regular "Be Safe. Drive Smart." campaigns that include Move Over awareness messaging on highway dynamic message signs, social media, and media partnerships. These campaigns often coincide with increased enforcement activity.

Real-World Scenarios: When Must You Move Over?

Understanding the law through real-world scenarios helps clarify your obligations:

Scenario 1: Police Car on Highway Shoulder

Situation: You are driving on I-35 at 70 mph. A police car is stopped on the right shoulder with flashing red and blue lights, conducting a traffic stop.

Your obligation: Move to the left lane if safe. If you cannot safely change lanes (heavy traffic, no gap available), slow down to 50 mph (20 below the 70 mph limit) until you have passed the police car.

Scenario 2: Tow Truck on Two-Lane Road

Situation: You are on a two-lane road with no passing lane. A tow truck with amber flashing lights is loading a disabled vehicle on the right shoulder.

Your obligation: Since there is no adjacent lane to move into, slow down to 20 mph below the posted limit. If the speed limit is 45 mph, reduce to 25 mph. If the limit is 25 mph or less, slow to 5 mph.

Scenario 3: Car with Hazard Lights on Freeway

Situation: A regular passenger car is stopped on the left shoulder of a freeway with its hazard lights flashing. A person is standing next to the car, apparently changing a tire.

Your obligation: Under the expanded law, the move over or slow down requirement applies to any vehicle displaying hazard lights. Move away from the left shoulder to a right lane if safe, or slow to 20 mph below the posted limit.

Scenario 4: Fire Truck Blocking a Lane

Situation: A fire truck is parked in the right lane of a three-lane highway at an accident scene, with flashing lights and cones directing traffic around it.

Your obligation: Follow the emergency scene traffic direction. Move to the farthest available lane from the fire truck. Slow down significantly. Follow any instructions from fire personnel or police officers directing traffic.

Scenario 5: TxDOT Crew on Median

Situation: A TxDOT maintenance truck with amber lights is parked on the median of a divided highway. Workers are trimming vegetation.

Your obligation: Move over or slow down, even though the vehicle is on the median rather than the right shoulder. The law applies to stopped vehicles displaying flashing lights on any part of the roadway or roadside, including medians.

Move Over Law and Large Vehicles: Special Considerations

Drivers of large vehicles (semi-trucks, buses, RVs) face additional challenges with Move Over compliance:

• Lane changes take longer — large vehicles need more time and space to safely change lanes. Plan ahead when you see flashing lights in the distance.
• Aerodynamic effects: Large vehicles create significant wind displacement when passing at speed. Even at reduced speeds, the aerodynamic wake of a semi can push a person standing on the roadside. This is one reason why slowing down is important even if you cannot move over.
• CDL implications: A Move Over violation for a CDL holder adds to their violation history and may affect CSA scores and employability.

What If You Cannot Safely Move Over?

The law explicitly recognizes that moving over is not always possible. You are not required to make an unsafe lane change. If you cannot safely vacate the lane closest to the stopped vehicle, you must slow down instead.

Situations where moving over may not be safe:

• Heavy traffic with no gap in the adjacent lane
• Two-lane road with oncoming traffic preventing a pass
• Road design — no adjacent lane exists (single-lane road, ramp, etc.)
• Another emergency scene on the opposite side of the road that also requires clearance
• Construction zone with lane closures preventing movement

In all of these situations, slowing to 20 mph below the posted limit satisfies your legal obligation. If the posted limit is 25 mph or less, slow to 5 mph.

How a Move Over Ticket Affects Your Driving Record and Insurance

Driving Record

• A standard Move Over violation (Class C misdemeanor) adds 2 points to your Texas DPS driving record
• If the violation involved property damage (Class B) or bodily injury (Class A), the conviction is more serious and may trigger additional DPS action
• The conviction remains visible on your 3-year record and permanently on your lifetime abstract

Insurance Impact

• Insurance companies treat a Move Over violation as a moving violation
• Expect a premium increase of 10%–25% for a standard violation
• If the violation resulted in an accident with property damage or injury, the insurance impact is significantly greater — potentially 30%–60%+
• The insurance increase typically lasts 3 years from the date of conviction

Can You Fight a Move Over Ticket in Texas?

Yes. A Move Over violation can be contested through the same options available for other traffic tickets:

Defensive Driving

A standard Move Over ticket (Class C misdemeanor, no property damage or injury) is eligible for defensive driving dismissal under the normal eligibility rules. This avoids a conviction and keeps the violation off your record.

Deferred Disposition

Available at the court's discretion. Plead no contest, complete probation conditions, and the ticket is dismissed.

Contesting at Trial

Common defense angles include:

• It was not safe to move over: If traffic conditions made a lane change dangerous, and you did slow down appropriately, you complied with the law
• The stopped vehicle was not displaying flashing lights: The law requires the vehicle to be displaying activated warning lights. If the lights were off, the obligation is not triggered.
• You did slow down: If you reduced speed to 20 mph below the posted limit (or 5 mph on low-speed roads) but the officer believed you did not slow enough, speedometer calibration and officer estimation errors can be challenged
• The vehicle was not on the roadside: If the stopped vehicle was in a parking lot, driveway, or private property adjacent to the road, the Move Over law may not apply

Roadside Safety: Protecting Yourself If You Are the Stopped Vehicle

If you are ever stopped on the roadside — whether for a breakdown, flat tire, or any other reason — you are in a vulnerable position. Protect yourself:

• Pull as far off the road as possible — get completely clear of travel lanes and as far onto the shoulder as you can
• Activate your hazard lights immediately — this triggers the Move Over obligation for passing drivers and increases your visibility
• Stay inside your vehicle if possible — you are safer inside a vehicle with hazards on than standing outside on the shoulder
• If you must exit, exit on the side away from traffic — the passenger side if you are on the right shoulder
• Use reflective triangles or flares if you have them — place them behind your vehicle to warn approaching drivers
• Wear bright or reflective clothing if you must stand outside, especially at night
• Call for help — 911 for emergencies, roadside assistance for breakdowns. A professional tow truck with amber flashing lights provides much greater visibility and safety than a car with only hazard lights.

Texas Move Over Statistics: Why This Law Matters

The human cost of failing to move over is real and documented:

• According to TxDOT, dozens of roadside workers, first responders, and stranded motorists are struck and killed on Texas roads annually
• The National Law Enforcement Officers Memorial Fund reports that being struck by a vehicle is consistently among the top causes of law enforcement line-of-duty deaths nationwide
• Tow truck operators have one of the highest fatality rates of any profession in the United States — roadside strikes are a primary cause
• Texas consistently ranks among the top states for total traffic fatalities, and roadside incidents are a significant contributor

The Move Over law is not just a revenue-generating traffic regulation — it exists because people are dying on Texas roadsides. Compliance takes only a few seconds and costs nothing. Non-compliance can cost a life — and potentially your freedom.
