According to ungerandkowitt.com, a person's driving record is essentially permanent. A speeding ticket received at age 16 will still be on the record at age 60. Most states, however, use a point system to determine the period of time in which tickets will have an effect on judicial repercussions.
DMV.org explains that the DMV point system used by most states has a refresh period of anywhere from one to three years. Certain driving related violations, such as DUIs, may remain on your record beyond this period and be factored into future court decisions. One example given by dmv.org is of the state of Wisconsin, in which a DUI will stay on the record and be taken into direct consideration for a period of 55 years.
