## Product Description
### Reliable, High-Visibility Stop Signs Built for Long-Lasting Performance

Our MUTCD R1-1 Stop Signs combine durable construction with exceptional nighttime visibility to help keep roads, parking lots, and intersections safe. Available in solid .080" aluminum or lightweight Aluminum Composite Material (ACM), these professional-grade stop signs feature 3M High Intensity Prismatic Reflective Sheeting for outstanding visibility in daylight, low-light conditions, and at night.

### Choose the Right Material for Your Application

**Solid .080" Aluminum:** Our traditional aluminum stop signs offer excellent strength, rigidity, and weather resistance for long-term outdoor installations. Made from solid, rustproof aluminum, they're an ideal choice for public roadways, commercial properties, and other locations where durability is a priority.

**Aluminum Composite Material (ACM):** A lightweight, economical alternative to solid aluminum, ACM features a durable polyethylene core bonded between two thin aluminum sheets. The result is a rigid, weather-resistant sign that delivers a professional appearance at a lighter weight. ACM stop signs are an excellent choice for parking lots, private roads, business parks, and commercial properties.

### High-Intensity Reflectivity for Enhanced Visibility

Every stop sign features 3M High Intensity Prismatic Reflective Sheeting that meets ASTM D4956 Type III and IV specifications and carries a 10-year performance warranty. The reflective surface helps motorists recognize stop signs from a distance, particularly at night when illuminated by headlights.

Available in 18", 24", 30", and 36" sizes, our R1-1 stop signs meet MUTCD design specifications and include pre-punched 3/8" mounting holes for convenient installation.
