What is the consequence of being convicted of driving more than 15 mph over the posted speed limit twice within a twelve-month period?

The correct consequence of being convicted of driving more than 15 mph over the posted speed limit twice within a twelve-month period is a 60-day revocation of your driver license. This penalty is designed to address repeated violations and encourages safer driving behavior. The revocation period is clearly outlined in North Carolina's traffic laws, which impose stricter penalties for repeat offenders, particularly in cases of significant speeding. By enforcing this 60-day revocation, the law aims to deter individuals from continuing to speed excessively, thereby promoting public safety on the roads.

The other options do not accurately reflect the stipulated consequences for this specific infraction based on North Carolina regulations. Understanding the implications of such driving behavior is crucial for maintaining compliance with traffic laws and ensuring personal safety as well as the safety of others on the road.
