City/County Patrol car will sit in median turn lanes on 321, especially past the rise of hills and uses instant-on radar at oncoming traffic. The speed limit on this four-lane divided highway varies from 65 to 45, but there are a minimal number of speed limit signs(1-2) on a 9-mile length of 321 between Granite Falls and Lenoir. Therefore, drivers are not properly informed of the legal speed limit – where there is speed limit variation of about 20mph.
