Demerit point

A penalty point or demerit point system is one in which a driver's licensing authority, police force, or other organization issues cumulative demerits, or points to drivers on conviction for road traffic offenses. Points may either be added or subtracted, depending on the particular system in use. A major offense may lead to more than the maximum allowed points being issued. Points are typically applied after driving offenses are committed, and cancelled a defined time, typically a few years, afterwards, or after other conditions are met; if the total exceeds a specified limit the offender may be disqualified from driving for a time, or the driving license may be revoked. Fines and other penalties may be applied additionally, either for an offense or after a certain number of points have been accumulated.

The primary purpose of such point systems is to identify, deter, and penalize repeat offenders of traffic laws, while streamlining the legal process. Germany introduced a demerit point system, in 1974, and one was introduced in New York at about that time.

In jurisdictions which use a point system, the police or licensing authorities (as specified by law) maintain, for each driver, a driving score—typically an integer number specified in points. Traffic offenses, such as speeding or disobeying traffic signals, are each assigned a certain number of points, and when a driver is determined to be guilty of a particular offense (by whatever means appropriate in the region's legal system), the corresponding number of points are added to the driver's total. When the driver's total exceeds a certain threshold, the driver may face additional penalties, be required to attend safety classes or driver training, be subject to re-examination, or lose his/her driving privileges.

The threshold(s) to determine additional penalties may vary based on the driver's experience level, prior driving record, age, educational level attained, and other factors. In particular, it is common to set a lower threshold for young, inexperienced motorists.

In some jurisdictions, points can also be added if the driver is found to be significantly at fault in a traffic accident. Points can be removed from a driver's score by the simple passage of time, by a period of time with no violations or accidents, or by the driver's completion of additional drivers' training or traffic safety training.

Major traffic offenses, such as hit and run or drunk driving may or may not be handled within the point system. Such offenses often carry a mandatory suspension of driving privileges, and may incur penalties such as imprisonment.
