North Carolina Traffic Laws, Signs, Signals, and Markings
This domain tests whether you can state North Carolina's rules of the road precisely enough to teach them, and whether you can read the control hierarchy at any intersection a student will meet.
Right-of-way and the control hierarchy
When devices conflict, authority runs: a police officer directing traffic, then a working traffic signal, then signs, then pavement markings. A green light is permission, not protection - it never cancels the duty to yield to vehicles already in the intersection and to pedestrians in a crosswalk.
North Carolina specifics to memorize
- Default limits: 35 mph in residential and business districts, 55 mph on most rural highways, 70 mph maximum on interstates; posted signs govern. School zones are 25 mph when posted or flashing.
- Right turn on red after a full stop unless a sign forbids it. NC also allows a left turn on red from a one-way street onto another one-way street after stopping.
- School buses: on a two-lane road, traffic in both directions stops for flashing red lights. Where a highway is divided into four or more lanes by a median, only traffic moving in the same direction as the bus must stop.
- Move Over: when an emergency, tow, or utility vehicle with flashing lights is stopped on the shoulder, change lanes away from it or slow substantially if a lane change is unsafe.
- Accumulating 12 driver points within three years triggers a DMV suspension; school-bus and work-zone violations carry elevated penalties.
Reading markings and shapes
Yellow lines separate opposing traffic - broken yellow allows passing, solid double yellow forbids it. White lines separate lanes moving the same direction. Shapes: octagon for stop, inverted triangle for yield, diamond for warning, pentagon for school, circle for railroad advance warning, crossbuck at the crossing itself.
Worked example
A student on a four-lane road with a raised median meets a stopped school bus showing red lights on the opposite side. Reason aloud: four lanes plus a median means the road is divided, so only same-direction traffic must stop. The student proceeds at a cautious speed, watching for children who may cross anyway.
Traps that cost marks
Confusing flashing yellow (proceed with caution) with flashing red (stop, then proceed). Assuming a green arrow protects you from a pedestrian still in the crosswalk. Stopping for a bus when the median exempts you - and, far worse, failing to stop when it does not.
