Their motto is: Know the Law; Obey the Law. In an effort to promote traffic safety around North Carolina schools, school buses and school bus stops, the Highway Patrol will conduct “Operation Stop Arm” this week through Friday, October 49, 2012. On average, each school bus is illegally passed once every day. According to the National Highway Traffic Safety Adminstration, 21 children under the age of 19 die every year getting on and off buses. The mission of Operation Stop Arm is to make school bus stops safe for our children. Again, the operation will be conducted statewide this week through Friday, 19 October.
