North Carolina DMV Practice Test 2026 - Free DMV Practice Questions and Study Guide

Passing on the right is deemed legal in North Carolina under specific conditions, particularly on a four-lane highway that features two lanes in each direction, or when driving on a one-way street. This is because those roadway designs allow for safe navigation around vehicles that are either traveling slowly or preparing to turn left, without crossing into oncoming traffic's lane.

On a four-lane highway with clearly designated lanes, the right lane can serve as a passing lane when the left lanes are occupied by slower-moving traffic. Similarly, in the case of a one-way street, vehicles traveling in the same direction can be passed on either side since traffic is only flowing in a single direction, minimizing the risk of a head-on collision.

In contrast, passing on a narrow road may not provide the necessary space to safely maneuver around a vehicle, and on a two-lane road, the rules are more restrictive due to the potential for conflicting lanes of traffic. The provision for passing on the right primarily acknowledges scenarios where it is safe and feasible, aligning with both legal standards and road safety principles.
