HOV 2+ Plaque Sign - R3-5c
High-occupancy vehicle (HOV) lanes play a critical role in traffic management and transportation efficiency. This R3-5c plaque sign provides clear guidance for drivers regarding lane eligibility, specifying the two-person minimum occupancy requirement for HOV lane access. Manufactured to meet DOT and MUTCD state and federal standards, the sign features high-intensity and diamond grade reflectivity on a standard aluminum blank. The durable construction ensures maximum visibility under various driving conditions, helping to reduce accidents and improve traffic flow by clearly communicating lane usage requirements. The sign comes standard with reflective materials on an aluminum base, featuring the official R3-5c designation that transportation departments recognize for HOV lane signage. Its design promotes safer roadways by providing drivers with immediate, unambiguous information about vehicle occupancy restrictions.
