Most Drivers Think They Know the 'Move Over' Law — Traffic Safety Data Says Otherwise

Almost every American driver believes they understand what to do when emergency vehicles are nearby. You pull over. You wait. You let them pass. Simple enough, right?

Except that's not actually what the law says in most states. And the gap between what drivers think the rule is and what it actually requires has contributed to hundreds of roadside deaths and tens of thousands of dollars in fines that drivers never saw coming.

The Assumption Most Drivers Share

When researchers and traffic safety organizations survey drivers about Move Over laws, a consistent pattern emerges: the overwhelming majority of respondents say they're aware of the law. They describe it as pulling over or slowing down for ambulances, fire trucks, and police cars with active lights and sirens.

That description isn't wrong, exactly. But it's dramatically incomplete — and the parts that are missing are the parts that actually get people killed and ticketed.

A 2021 survey conducted by the National Safety Commission found that while roughly 70 percent of drivers claimed familiarity with Move Over laws, fewer than one in four could accurately describe what the law required in their specific state. Most didn't know it applied to stopped vehicles. Most didn't know it covered non-emergency workers. And almost none knew the fine structure.

What 'Move Over' Laws Actually Require

Every U.S. state now has some version of a Move Over law on the books — the last holdout, Hawaii, passed its version in 2012. But the specifics vary considerably, and assuming your state's version matches what you learned in driver's ed is a gamble.

The core requirement in most states goes beyond responding to a moving emergency vehicle with sirens wailing. The law typically applies to stopped vehicles on the side of the road — and that's where most drivers get tripped up.

In the majority of states, if you're traveling on a multi-lane road and you see a stopped emergency vehicle with its lights activated on the shoulder, you are legally required to either:

• Move over one full lane away from the stopped vehicle, or
• If changing lanes isn't safely possible, slow to a speed significantly below the posted limit — often 20 mph under, depending on the state.

The critical word there is stopped. You don't need to hear a siren. You don't need to be in the vehicle's path. If there's a police cruiser parked on the shoulder with its lights flashing, the law applies to every driver passing it in the nearest lane.

It's Not Just Police and Ambulances

Here's where the law gets even broader than most drivers expect: in a growing number of states, Move Over requirements now extend well beyond traditional emergency responders.

As of recent years, states including Florida, Texas, Georgia, and more than two dozen others have expanded their statutes to include tow trucks, utility vehicles, highway maintenance crews, and in some cases, any vehicle displaying amber warning lights. In Texas, the law covers any vehicle with hazard lights activated on the shoulder — including a fellow motorist who's pulled over with a flat tire.

This expansion came directly in response to data. Tow truck operators and highway workers are killed at roadside at alarming rates. The Emergency Responder Safety Institute has documented hundreds of incidents in which workers were struck by passing vehicles while attending to stopped vehicles on the shoulder. Expanding Move Over coverage was a direct legislative response to that pattern.

If you're in a state with an expanded statute and you didn't know about it, you've likely passed plenty of tow trucks in the right lane without moving over — and technically broken the law each time.

The Fines Are Not Small

Move Over violations aren't the kind of infraction that comes with a $50 slap on the wrist. In most states, a first offense runs between $100 and $500. In Florida, fines can reach $500 for a first violation and escalate sharply if the offense results in injury or property damage. In some states, a Move Over violation that injures a worker is classified as a misdemeanor or worse.

Georgia and North Carolina have both made headlines for aggressive Move Over enforcement campaigns, with officers specifically deployed to ticket violators near construction zones and incident scenes. Drivers who assumed they were in compliance — because they slowed down slightly or moved a few feet toward the center line — found out the hard way that the law required a full lane change.

Why Awareness Campaigns Haven't Worked

Traffic safety researchers point to a specific psychological barrier that makes Move Over education unusually difficult: drivers are already convinced they understand it.

This is what researchers call the "illusion of knowing" — a well-documented cognitive pattern where partial familiarity with a topic makes people resistant to learning more about it. If someone asks whether you know the Move Over law and you say yes, you're unlikely to read the brochure. You already know.

Public awareness campaigns run by state DOTs and highway safety organizations have repeatedly found that messaging framed as "learn about Move Over laws" underperforms dramatically compared to messaging framed as "the Move Over law is different than you think." The second framing creates a gap in confidence that motivates people to actually pay attention.

The problem, as one traffic safety researcher put it, is that drivers don't know what they don't know — and nothing in their daily driving experience flags the gap for them until they're holding a citation.

What to Actually Do

The practical takeaway here is straightforward, even if it requires unlearning a habit. Whenever you see any vehicle stopped on the shoulder with lights flashing — emergency or otherwise — your default should be to check your mirrors, signal, and move one full lane away if traffic allows. If it doesn't, slow down meaningfully before you pass.

Look up your specific state's statute. Most state DMV websites publish the current version, and it takes about three minutes to read. Given the fines involved, and more importantly given the people standing on those shoulders, it's three minutes well spent.
