One Way Signs

One way signs improve pedestrian safety by letting pedestrians look for traffic in only one direction rather than two, improve unidirectional traffic flow by reducing stop-and-go driving in congested areas, create smoother-moving traffic by preventing cut-through traffic, and improve parking lot safety by directing drivers to the correct path to a parking space or exit.

A one way sign is needed anywhere traffic should only travel in a single direction, such as a narrow street, alleyway, or parking lot, to help prevent head-on collisions and keep traffic moving smoothly and predictably.

Yes, one way signs are regulatory signs, meaning they inform road users of a legal traffic requirement. The MUTCD R6-1 one way sign must be at least 36" x 12" on single-lane roads and 54" x 18" on multi-lane roads or freeways, while the MUTCD R6-2 one way sign starts at 18" x 24" and scales up to 48" x 60" on freeways. Since size and mounting requirements can vary by state, checking local traffic laws before ordering is recommended.

The MUTCD R6-1 one way sign is a horizontal black rectangle with a white border, with "ONE WAY" in black over a large white arrow. The MUTCD R6-2 one way sign is a vertical white rectangle with a black border, with "ONE WAY" in black above a black arrow.

One way signs come in three reflectivity grades: Engineer Grade, the standard option lasting at least 7 years outdoors; High Intensity Grade, offering up to three times the reflectance; and Diamond Grade, offering ten times the reflectivity and at least 12 years of outdoor life, best suited for busy city streets.

One way magnetic signs are die-cut arrow shapes made from 32 mil rubber embedded with magnetic ferrite particles, giving them a flexible magnetic backing that applies to any metal surface and repositions easily without residue. They're a good fit for temporary uses like one-way store aisles, and a reflective version is also available for nighttime visibility.
