A failure to use a turn signal is a traffic infraction in every state, with base fines that generally run from $50 to $200 before court fees and surcharges are added. The ticket itself is only the start. Points on your driving record, higher insurance rates at renewal, and a clear finding of fault if you cause a crash all mean this “minor” violation can cost far more than the citation suggests.
When the Law Requires a Signal
Signaling is not just for intersections. You have to signal before changing lanes, merging onto a freeway, pulling away from a curb, and exiting a roundabout. Any lateral movement or change of direction has to be signaled first.
The standard distance in most states is at least 100 feet before the turn or lane change, roughly five or six car lengths. Some states require more distance at higher speeds, but 100 feet is the floor almost everywhere.
If your signal lights are burned out or malfunctioning, you’re still required to signal, and every state recognizes hand signals as a legal substitute. A broken signal light can itself draw a citation, though in many jurisdictions it’s treated as a correctable or “fix-it” violation: repair the light, show proof to the court, and the ticket gets dismissed. Simply not signaling when your equipment works is not correctable.
What the Ticket Actually Costs
Base fines land in the $50 to $200 range in most states. Iowa sits near the low end; California and Michigan push toward the top. Several states use a tiered structure that raises the fine for repeat offenses within a set period.
The base fine is rarely the number you write the check for. Court processing fees, state surcharges, and penalty assessments can double or triple it. A $100 base fine often becomes $250 or more once everything is added. Contest the ticket and lose, and some jurisdictions tack on hearing costs too.
Points on Your License
Most states assign one or two points for a turn signal violation. Points are how the state tracks risky driving, and each one narrows the margin before something worse happens.
How long they stay on your record varies. Some states clear them after two years, others hold them for three to five, and a few keep them visible longer for insurance purposes. The real problem is accumulation. Every state sets a threshold where too many points in a given window triggers a suspension. One signal ticket won’t get you there. Combine it with a speeding ticket and a rolling stop, and the line gets closer than most drivers expect.
Traffic School Can Keep the Point Off
Most states let you attend a defensive driving or traffic school course to keep a minor violation from adding a point. The court usually has to approve your enrollment, and you’ll pay a course fee on top of the fine. This option is typically available once every 12 to 18 months, so it’s worth saving for a ticket that would do the most damage. The course doesn’t erase the citation, but it prevents the point from surfacing when insurers pull your record.
How It Hits Your Insurance
Insurers look at patterns more than single events. A lone turn signal ticket on an otherwise clean record may not move your premium much. But insurance companies check your driving history when you apply, get a quote, or come up for renewal, and any violation sitting there at that moment feeds into their risk calculation.1Car and Driver. How Often Do Car Insurance Companies Check Your Driving Record
Two or three moving violations within a couple of years read as a pattern to underwriters, and that’s where you start seeing real rate increases. Completing a defensive driving course sometimes qualifies you for a discount that offsets part of the damage, though availability and size depend on the insurer.
Fighting the Ticket
You can contest any traffic citation, and turn signal tickets are among the easier ones to challenge because whether you signaled is often a judgment call. The officer has to have observed the specific moment you failed to signal, and heavy rain, sun glare, or obstructed sight lines can undermine that observation.
To contest, notify the court by the deadline printed on the citation. At the hearing, both you and the officer present your accounts. Dashcam footage, witness statements, or photos showing conditions at the intersection are all useful evidence. If the citing officer doesn’t appear, many courts dismiss the ticket outright.
Common arguments include that you did signal but the officer’s vantage point made it hard to see, that road conditions made signaling unsafe (an emergency maneuver that required both hands on the wheel, for instance), or that the officer misidentified your vehicle. Success rates vary, but contesting is worth considering when the facts back you up.
If You Hold a CDL, the Stakes Are Higher
Commercial drivers operate under stricter federal rules. “Making improper or erratic traffic lane changes” is classified as a serious traffic violation for anyone who holds or is required to hold a commercial driver’s license.2eCFR. 49 CFR 383.51 – Disqualification of Drivers One conviction is a mark on your record. The second is where it bites.
Two serious traffic violation convictions within three years result in a 60-day disqualification from operating any commercial motor vehicle. A third within the same window extends that to 120 days.2eCFR. 49 CFR 383.51 – Disqualification of Drivers For a truck driver or bus operator, that’s lost income and potentially a lost job. The disqualification applies even if the violation happened in a personal vehicle, as long as it resulted in a suspension or revocation of the driver’s non-commercial privileges.
If a Missing Signal Causes a Crash
Failing to signal and then colliding with another vehicle is one of the clearest negligence fact patterns there is. You had a duty to signal, you didn’t, and someone got hurt. That satisfies every element: duty, breach, causation, damages.
In a personal injury lawsuit, the missed signal becomes powerful evidence. The injured driver can seek medical bills, lost wages, vehicle repair costs, and pain and suffering. Courts weigh police reports, witness accounts, and any camera footage. The citation itself, while not conclusive proof of fault, is typically admitted and carries weight with juries.
Comparative Negligence Can Reduce What You Owe or Recover
Crashes are rarely 100% one driver’s fault. If the other driver was speeding or distracted, a court may split responsibility. Most states follow some version of comparative negligence, which reduces recovery by the injured party’s percentage of fault.3Legal Information Institute. Comparative Negligence
Rules vary. Pure comparative negligence lets you recover even if you were 99% at fault, though your award shrinks to match. Most states follow a modified version that bars recovery entirely once your fault hits 50% or 51%, depending on the state.3Legal Information Institute. Comparative Negligence If you failed to signal but the other driver ran a red light, a court might assign 30% fault to you and 70% to them, adjusting damages accordingly.
When It Can Turn Criminal
A turn signal violation on its own never results in criminal charges. But when the missed signal contributes to a crash that injures or kills someone, prosecutors may fold it into a broader charge like reckless driving or vehicular manslaughter. The signal failure alone isn’t enough. Prosecutors need a pattern of dangerous driving or a level of recklessness beyond a single oversight. Changing lanes without signaling while speeding and weaving through traffic starts to look like the kind of disregard for safety that supports a reckless driving charge.
Vehicular manslaughter laws vary significantly by state, but penalties for a fatal crash caused by reckless driving generally include substantial fines, license revocation, and imprisonment. Sentences can range from one year to fifteen years or more depending on the jurisdiction and the charges filed. These cases are rare in the context of a simple missed signal, but they show how a small violation can become part of a much larger legal problem when it contributes to serious harm.
