The Aluminum DO NOT PASS Sign (R4-1) features two top and bottom centered, pre-punched mounting holes and can be easily installed on a post, wall, or fence. Used to alert drivers to an area where passing is unlawful. With standard federal radius corners and 3M™ reflective sheeting, this sign meets MUTCD specifications and is designed to be a durable traffic control solution.
| Grade | Sheeting |
|---|---|
| Engineer Grade (EG) | Increases visibility of signs when light hits their surface. Ideal for parking lots and driveways. |
| High Intensity Prismatic (HIP) | Enhances visibility when viewed at an angle. Recommended by MUTCD as the “best practice” reflective option for roadways and other high traffic areas. |
| Diamond Grade (DG) | Has greater luminescence than EG and HIP and can be seen from greater distances. Ideal for potentially hazardous intersections, high traffic areas, and large signs that need to be seen from a distance. |
