Install it in parking garages, on gate arms, and at narrow posts where a square symbol plate is the only thing that fits.
R8-3 Questions
Why is the R8-3 square?
It carries the no parking symbol alone with no text, so a square blank fits the graphic without wasted space. That makes it usable where a vertical rectangle will not fit.
Where does a square symbol no parking sign work best?
Parking garages, gate arms, and narrow posts, where the mounting position dictates the sign shape.
R8-3 Important Information
A No Parking Symbol is a regulatory traffic sign that indicates an area where parking is prohibited, often featuring a red circle with a red diagonal line crossing over a black letter P. The sign is used to enforce parking restrictions, maintain traffic flow, and ensure that parked vehicles do not obstruct emergency access or impede the movement of other road users.
R8-3 Reflective Sheeting Options
Because the R8-3 is often posted along open curbs and travel lanes where drivers approach at speed, the T-11500 OmniCube - up to 60 percent brighter with a 12-year outdoor durability rating - is the safer choice when night visibility matters most, while the T-6500 High Intensity Prismatic delivers proven 10-year durability.
- Most Common Reflective Finish
- Very Reflective At Night
- Required for Most Highway Signs
- 10 Year Outdoor Durability
- Brightest and Most Visible
- Most Reflective At Night
- Up to 60 percent brighter than HIP
- 12 Year Outdoor Durability
The R8-3 puts a red/black legend on a white reflective background, and white returns more light than any other color under ASTM D4956, so nearly the entire face lights up under headlights. That is why stepping up to the T-11500 OmniCube produces such a visible change on this sign: you are brightening the color that already dominates the sign face.
