Warning signs are typically diamond-shaped and yellow in color. These signs warn drivers of potentially hazardous conditions, road changes, pedestrians and heights of overpasses. Additional warning signs include school crossings, lane merges, no passing zones, no shoulder and deer crossing.
Aside from stop signs and yield signs, regulatory signs are typically square or rectangular in shape, with a white background behind black or red print. Signs indicating no turns, left-turn only, no bicycles, do not enter and no u-turn are regulatory signs. Parking signs are also considered to be regulatory signs, and include handicapped parking, no parking and emergency parking only.
The North Carolina driving test consists of four parts: a written test, a sign test, a vision test and a road test. The written tests covers traffic laws and approaches to driving; the vision test is given to ensure drivers do not need corrective lenses in order to safely operate a vehicle or read road signs; and the road test demonstrates a driver's actual ability to operate a vehicle and follow the laws of the road. This test is only given after the driver passes all other components of testing.
