On American highways, the most dangerous moments often happen after the lights are already on. A traffic stop, a tow, or a breakdown leaves people working inches from fast traffic, and many states have tightened Move Over rules to build a safer buffer. In 2026, the strictest versions do two things: they widen who is protected and they spell out what drivers must do, with clear speed drops, lane changes, and meaningful penalties. The result is a patchwork that rewards attention and punishes autopilot.
Connecticut
Connecticut’s Slow Down, Move Over rule is strict because it applies to any vehicle stopped on or next to a highway, not only to emergency lights, broadened in 2017. On multilane roads, drivers are expected to shift one lane away when it is reasonable and safe, and, either way, immediately reduce speed to a reasonable level, often below the posted limit. That extra scope changes the feel of I-95 and the Merritt after dark, when hazard lights can signal a medical scare, a dead battery, or a tow in progress, and the law treats that shoulder as occupied space where a brief lapse can turn a minor problem into a crash.
New York
New York’s move over requirement became harder to ignore after its Mar. 27, 2024 expansion to cover any vehicle parked, stopped, or standing on the shoulder of a controlled-access highway or parkway. The practical rule is to change lanes away when traffic allows, and otherwise slow down and drive with due care, rather than squeezing by at full speed or hugging the fog line. On the Thruway and other corridors, that shift matters because it protects stranded drivers before help arrives, when the shoulder is most vulnerable and a passing car’s “close enough” can become a life-changing impact in a second in darkness or winter spray.
Virginia
Virginia ties its rule to the warning scene, not the uniform. On highways with four or more lanes, drivers must move over or slow down for stationary vehicles displaying emergency or amber warning lights, and the state also calls out hazard lights, caution signs, flares, and similar signals. It is strict because it treats roadside warnings as a protected space, even when the stopped vehicle is not a cruiser or a tow truck. That framing fits the reality of fast interstates where rain and headlight glare erase depth, and the safest moment to create a buffer lane is well before a door opens or a person steps into the shoulder.
Florida
Florida’s law is strict in two ways: it protects a wide mix of roadside workers, and it adds disabled vehicles to the covered group, not just official responders. When a stopped vehicle is on the side of the road, drivers should move over a lane if it is safe, and when they cannot, state guidance sets a clear slowdown of 20 mph under the limit, with a drop to 5 mph on roads posted at 25 mph or less. That clarity matters on long, straight stretches where speed feels routine, because sanitation trucks, utility crews, tow operators, and stranded families can all appear with almost no warning in the headlight wash.
New Jersey
New Jersey makes the expectation blunt: when stationary emergency vehicles, tow trucks, garbage trucks, or other highway safety vehicles show red, blue, or amber lights, the nearest lane is no longer a casual passing lane. Drivers must move over one lane when possible, and if moving over is unsafe, they must slow down below the posted limit and pass with care instead of riding the line or darting back in at the last second. In a dense, high-merge state, that matters because amber lights are common on the Turnpike and the Parkway, and the rule treats a shoulder scene like a live work zone where space is part of the safety equipment.
Illinois
Illinois treats Move Over violations as a serious offense under Scott’s Law, and the penalties explain why drivers feel the pressure. The duty is to change lanes away from vehicles with flashing lights, including emergency response and service vehicles, or slow down and proceed with caution when a lane change is not possible. State police spell out consequences that escalate fast: fines from $250 to $10,000, license suspensions that lengthen when damage or injury occurs, and charges that can rise to a Class 4 felony when a person is injured or killed, with extra court consequences that keep it from feeling like a routine ticket.
Tennessee
Tennessee’s rule is stricter than many drivers expect because it includes more than responders. State law covers stationary emergency and recovery vehicles with flashing lights, and it also addresses a stopped vehicle using flashing hazard lights, requiring a lane change when possible or a careful slowdown when it is not. The penalty language can include a fine of up to $500 and possible jail time, which keeps the rule from being treated as a suggestion. On rolling interstates where a stopped car can hide just beyond a crest, the law’s broad scope pushes drivers to make room early, not at the last instant.
Colorado
Colorado is strict because it puts numbers on the slowdown and expanded coverage to any vehicle stopped on the roadside. Drivers are expected to move over at least one lane when possible, and when that cannot be done safely, they must slow to a defined “safe speed,” including a reduction of at least 20 mph in higher-speed zones. That specificity removes the common excuse of guessing what courtesy looks like at 70 mph, a change reinforced by the 2023 update. On I-70 grades and sudden weather shifts, the law treats every shoulder stop as a potential rescue scene, whether it is a trooper, a tow, or a stranded driver waiting in the cold.
Washington
Washington’s law is strict because it pairs a move-over duty with a clear speed target when moving over is unsafe. If drivers cannot change lanes away from a stopped emergency or work vehicle using flashing warning lights, they must reduce speed to at least 10 mph below the posted limit, with a cap that effectively forces 50 mph when limits exceed 60 mph. That hard number changes behavior in rain, darkness, and heavy traffic, when lane changes can be risky and late braking causes chain reactions. It matches the state’s reality: tow operators and responders work in narrow margins, and a predictable slowdown gives them a fighting chance.
Texas
Texas leans strict through reach and recent updates. Drivers must move over a lane or slow down when approaching law enforcement, tow trucks, utility vehicles, TxDOT vehicles, and other covered responders with activated overhead lights, and state guidance points to slowing 20 mph under the limit when a lane change is not possible. Since Sept. 1, 2025, coverage expanded to include animal control officers and parking enforcement employees, widening the everyday roadside scenes protected by the same rule. On long rural corridors and crowded metros alike, the message is consistent: overhead lights mean space, every time.
