Yes, it is illegal to speed up when someone is passing you. Every U.S. state’s traffic code requires the driver being overtaken to hold a steady speed or slow down until the pass is complete, and accelerating to block the maneuver violates that rule. The prohibition comes from the Uniform Vehicle Code, the model law nearly every state has adopted, which says the overtaken driver “shall not increase the speed of the vehicle until completely passed by the overtaking vehicle.” Depending on how the behavior unfolds, it can draw anything from a basic traffic citation to a criminal reckless driving charge.
What the Law Requires of You
When another vehicle moves to pass you, your legal duty is simple. Don’t speed up. Every state’s version of the rule traces back to Section 11-303 of the Uniform Vehicle Code, which directs the overtaken driver to give way to the right and maintain or reduce speed until the pass is finished.
In practice that comes down to three things:
- Hold your speed. Keep your foot steady. Even a small increase extends the time the passing car spends exposed, and on a two-lane road that time is spent in the oncoming lane.
- Move right when it’s safe to do so. If your lane gives you room, drift toward the right side of it. You’re not required to leave the travel lane.
- Stay predictable. No sudden braking, no swerving. The passing driver committed to the maneuver based on where you were and how fast you were going.
Your obligation doesn’t depend on whether you think the pass was wise, whether the other driver signaled, or whether they honked first. The rule applies the moment they begin to overtake you.
Penalties for a Basic Violation
Charged as a straightforward traffic infraction, speeding up while being passed carries the same kind of penalties as most moving violations.
- Fines. First-offense fines in most jurisdictions fall between $85 and $250, though court costs and surcharges push the final total higher. The base amount varies by state and sometimes by county.
- License points. States with point systems typically assess two to four points for an improper passing or failure-to-yield conviction, depending on how the offense is classified.
- Suspension exposure. A single violation won’t normally cost you your license. Points accumulate, though, and in most states hitting 12 to 15 points within a set period puts your license at risk.
The numbers look modest on their own. They compound quickly when a driver picks up two or three moving violations in a short window, and each conviction feeds into an insurance history that lasts far longer than the citation itself.
When It Becomes Reckless or Aggressive Driving
Doing this once might get you a basic citation. Doing it deliberately, repeating it, or combining it with tailgating, brake-checking, or gesturing at the other driver puts you in a different legal category.
About a dozen states have specific aggressive driving statutes, which generally define the offense as committing multiple moving violations in a single incident while endangering other people. Failure to yield to an overtaking vehicle and improper lane behavior show up on these lists. Virginia’s statute, for instance, explicitly includes failing to give way to a passing vehicle as a qualifying violation. In states without a dedicated aggressive driving law, the same conduct usually falls under the broader reckless driving statute, which covers operating a vehicle with willful disregard for safety.
The difference matters. A failure-to-yield infraction is a ticket with a fine and points. A reckless driving conviction is a criminal misdemeanor in most states, with potential jail time, higher fines, and a permanent criminal record. If the behavior causes a crash that injures someone, the charges can escalate again from there.
If You Hold a Commercial Driver’s License
Commercial drivers face a second layer of consequences that applies even when they’re driving a personal vehicle. Federal law defines “serious traffic violations” for CDL holders, and the list includes improper or erratic lane changes, reckless driving, and excessive speeding—any of which can describe accelerating to block a pass, depending on how the officer writes the citation.1Office of the Law Revision Counsel. 49 USC 31301 – Definitions
The federal disqualification schedule is unforgiving:
- Two serious violations within three years: 60-day CDL disqualification.
- Three or more serious violations within three years: 120-day CDL disqualification.
These disqualifications apply even when the offense happened in a personal vehicle.2eCFR. 49 CFR 383.51 – Disqualification of Drivers For someone whose income depends on a CDL, two citations in a three-year window can mean two to four months unable to work. That financial hit dwarfs any fine attached to the underlying ticket.
Insurance and Civil Liability
A conviction for improper passing or failure to yield almost always triggers an insurance rate increase. Industry data suggests an improper passing conviction raises premiums by roughly 14 percent on average, and a failure-to-yield conviction by about 9 percent. Those are averages, so half of drivers see larger increases. The surcharge typically lasts three to five years from the conviction date.
If speeding up contributes to a crash, the civil side gets worse fast. A traffic violation that causes an accident can establish negligence in a lawsuit, which means the injured driver may not need to prove you were unreasonable; the violation itself can carry that weight. Damages can include medical bills, lost wages, vehicle repairs, and pain and suffering. Your insurance covers some of this up to the policy limit. Anything above that limit comes out of your own assets.
What to Do Instead
The urge to speed up is more common than most drivers realize, and it often isn’t conscious. You’re cruising at 55, another car pulls out to pass, and your foot presses down slightly because some part of your brain reads the pass as a challenge. Noticing that reflex is most of the work.
When you see a vehicle move into the oncoming lane to pass, ease off the accelerator a little. You don’t need to brake hard or pull onto the shoulder. Hold steady, or let your speed drop by a few miles per hour. The pass will be over in seconds. If the passing driver misjudged the gap and is running out of room, slowing more firmly gives them space to get back in safely. That isn’t a favor to them. It’s the move that keeps a routine maneuver from turning into a head-on collision, a criminal charge, or a lawsuit with your name on it.
