New Jersey Statutes Title 39. Motor Vehicles and Traffic Regulation 39 § 5-30.9

Points recorded against a licensee shall be reduced at the rate of three points for each 12 consecutive months in which the licensee has not committed any violation either resulting in the assessment of points or in the suspension of driving privileges. Points recorded against a licensee shall also be reduced by three points, where the licensee attends and satisfactorily completes an approved license improvement course; provided, however, that no licensee may receive point reduction credits for completion of the same or a similar course within two years of having completed the original course. Points recorded against a licensee shall also be reduced by two points if the licensee attends and satisfactorily completes an approved motor vehicle defensive driving course pursuant to section 55 of P.L.1990, c. 8 (C.17:33B-45), except that no licensee may receive point reduction credits for completion of an approved motor vehicle defensive driving course within five years of having completed a previously approved motor vehicle defensive driving course. No point totals shall be reduced below zero. Computation of the time periods used in granting point reduction credits shall in all cases be based upon the respective dates of commission of the offenses for which the licensee was convicted and assessed points.
