Insurance after a ticket: what a course can change

Insurers set their own rates. A few states write numbers into law: a minimum discount for a defensive driving course, or a rule about what insurers may see. This guide lists the figures states publish. Where none is published, the discount varies by insurer.

Your driving record is part of your premium

Insurers read your driving record when they price a policy. The California Department of Insurance says insurers use the record of every driver in the household to decide whether to insure you and at what price, and that a surcharge usually follows an accident or a moving violation that was the covered driver's fault. Source: California Department of Insurance, Automobile Insurance, Form 101 revised February 5, 2025.

California also sets a floor. A Good Driver, licensed for at least three years in a row with no more than one point on the record, must pay at least 20% less than a driver who does not qualify, at the same company. One ticket can carry a point, and the California rule keeps the point of one masked ticket in any 18 months off the record insurers see (checked October 2026).

Defensive driving discounts written into state law

Five state rules put a number on the discount for a voluntary course (checked October 2026). Each figure holds on the terms its source sets, often an age floor, and your insurer applies it.

Published insurance figures for a voluntary course, checked October 2026
StatePublished figureSource
ConnecticutAt least 5% for at least 24 months, for drivers 60 and olderConn. Gen. Stat. 38a-683, Premium discount for senior citizens completing an accident prevention course
LouisianaUp to 10% for 36 months, where the insurer has filed a reductionLouisiana R.S. 22:1457 Discounts; rate reductions
MinnesotaAt least 10% for drivers 55 and older, renewed every 3 yearsMinn. Stat. 65B.28, Accident prevention course premium reductions
New York10% off the base rate of liability and collision premiums for three yearsPoint and Insurance Reduction Program (PIRP), NY DMV (Internet Archive capture of 2026-08-13)
PennsylvaniaAt least 5% for drivers 55 and olderMature Driver Improvement Course, PennDOT Driver and Vehicle Services

Two of the figures come with conditions. Louisiana's reduction does not apply when a court ordered the course. New York's figure comes with the Point and Insurance Reduction Program, the same course that lets the DMV subtract up to 4 points when it counts toward a suspension (New York rule, checked October 2026).

Everywhere else, the discount varies by insurer

Another 15 state rules mention a voluntary course that can count toward an insurance discount, with no figure: California, Delaware, Washington, DC, Florida, Georgia, Idaho, Kentucky, Maine, Montana, New Jersey, Oklahoma, Oregon, Texas, Virginia and Washington. In those states, and in every other, whether you get a discount, how much and for how long varies by insurer.

The checker prints a figure under an answer only where the state publishes one. Otherwise it says: Insurers set their own rates; ask yours.

What to ask your insurer

  • Does a moving violation change the premium, by how much, and for how long?
  • Do you give a discount for a defensive driving or accident prevention course, which courses count, and for how many years?
  • Does a course taken for a ticket count, or only a voluntary one? Louisiana's law leaves out a course a court ordered.
  • Which record do you read, and does it show a dismissed or masked ticket?

Questions

Does traffic school lower car insurance?
Where a state or your insurer says so. Five state rules publish a figure for a voluntary course, each on its own terms: at least 5% in Connecticut and Pennsylvania, up to 10% in Louisiana, at least 10% in Minnesota, and 10% off the base rate in New York. California and Michigan keep a masked ticket from insurers. Elsewhere it varies by insurer.
How long does a ticket affect car insurance?
Your insurer decides, and the rules we read publish no single period. How long points count on your license is a separate question each state answers; the state pages list it.
Does one ticket cost the California Good Driver discount?
A Good Driver in California has no more than one point on the record and must pay at least 20% less than a driver who does not qualify, according to the California Department of Insurance. A second point puts a driver over that line. Traffic Violator School keeps the point of one ticket in 18 months off the record insurers see.
