Suspension and Revocation
Beyond that, if you are dinged 11 points for traffic convictions in an 18-month period, the New York DMV may suspend or revoke your license for (usually) 31 days. You may be given the option to appear for a hearing with an administrative law judge to argue that someone else committed the offense instead of you, but be careful: The judge may actually increase the period of suspension or revocation originally imposed by the DMV. Points are assessed according to the date of the offense, not the date of the conviction.
NEW YORK DMV POINT SYSTEM

* Speeding (11-20 MPH over posted limit): 4 points

The point system is not the only way to lose your license; there are mandatory suspensions and revocations outside this classification. For example, your license will be suspended for three speeding violations within 18 months even if your total is less than 11 points. And serious offenses such as driving while under the influence of alcohol or drugs carry serious consequences, starting with a six-month license revocation.
While the traffic convictions themselves remain on your record for at least three years, the points are automatically removed from your total 18 months after committing an offense. You may also remove four points from your total by completing an accident-prevention course approved by the DMV (read the DMV's Point and Insurance Reduction Program brochure).
The DMV has provided a summary of the state point system, and you might also want to read in detail about other traffic offenses and reasons you might lose your license.
