What is speed north-carolina?

As an AI language model, I do not have up-to-date information on current speed limits or traffic conditions in North Carolina, but according to the North Carolina Department of Transportation website, the maximum speed limit on most NC highways and interstates is 70 mph for passenger cars and 55 mph for trucks and combination vehicles over 26,000 lbs. However, there may be lower speed limits in areas such as residential neighborhoods or school zones. Drivers should always obey speed limit signs and adjust their speed according to road and weather conditions for safety.
