If it was your son's first ticket, he might not see any change in his rates. Some states have laws governing when and why auto insurers can change policyholders' premiums; often, insurers are not allowed to raise your rates after just one speeding ticket or other citation. Different companies have different practices when it comes to raising premiums. Some companies will consider the severity of your violation and raise your rates accordingly; others will raise rates a specific amount per violation.

Typically, an auto insurance company has the right to review the driving record of anyone who applies for an auto insurance policy from that company. If a review of your driving record uncovers negative information, there's a chance your insurance rates will increase. Insurers typically use their own "point" system to determine the amount of the increase (if any). Although these systems can vary, most insurers use a system based on the Safe Driver Insurance Plan, which is issued by the Insurance Services Office (ISO).
