Most states penalize drivers who violate traffic and criminal laws while operating a motor vehicle by restricting, suspending, or revoking the driver’s license. For example, a state may suspend a driver’s license upon refusal to submit to a blood or breath test when suspected of driving under the influence of alcohol or drugs or when a driver is convicted of driving under the influence of alcohol or drugs.

And most states have a traffic ticket points system that assigns points to traffic offenses—with more serious offenses receiving more points. The points a driver accumulates become a part of the driver’s record with the state and a specified number of points will lead to greater driver’s license penalties—including suspension of the driver’s license—as well as higher insurance premiums charged by insurance companies.

The use and structure of traffic ticket point systems vary from state to state and are usually located in a state’s statutes.

In Nevada, the Department of Motor Vehicles (DMV) operates a demerit point system for traffic violations. When a driver is convicted of traffic offenses, points are added to their driving record. Minor infractions may carry fewer points, while more serious offenses, such as driving under the influence (DUI), can result in a higher number of points. Accumulating 12 or more points within a 12-month period will result in an automatic driver's license suspension for six months. Drivers are notified by mail before suspension takes effect and have the right to request a hearing. Regarding DUI offenses, Nevada law mandates the suspension of a driver's license upon refusal to submit to a blood or breath test, as implied by the state's implied consent law, or upon conviction of a DUI. The length of the suspension varies depending on the severity of the offense and whether it is a first or subsequent violation. Additionally, DUI convictions can lead to mandatory installation of an ignition interlock device and other penalties. Insurance premiums are likely to increase with traffic violations, as insurers consider a driver's record when determining rates.
