ROAD CLOSED Sign Requirements
This guide summarizes the MUTCD requirements and practical application guidance for the R11-2 ROAD CLOSED sign. Use this resource to understand when it is required, how to place it correctly, and how to maintain clear visibility for safe operations.
When It Is Used
Full roadway closures at the closure point
Where It Applies
At the closure point (activity area), typically on a barricade.
Placement Basics
Mount at the standard height and setback for the roadway with clear sight lines.
Visibility / Reflectivity
High reflectivity and clear sight lines are essential day and night.
1. When a ROAD CLOSED Sign Is Used
A regulatory sign stating that the road is closed to all traffic, posted at the closure point typically on a barricade across the roadway.
- Full roadway closures at the closure point
- Mounted on Type III barricades
- Used with W20-3 advance warning and detour markers
2. How and Where It Applies
In the field, R11-2 Road Closed is typically positioned at the at the closure point (activity area), typically on a barricade. Common deployments include full roadway closures at the closure point; mounted on Type III barricades; used with W20-3 advance warning and detour markers. Always confirm its size, retroreflective sheeting, spacing, and placement against the CA MUTCD 2026 and the reviewing agency before finalizing the traffic control plan.
3. Placement and Application Notes
Position R11-2 at the closure point (activity area), typically on a barricade.
- Place the sign where drivers have a clear, unobstructed view on approach.
- Mount at the standard height and setback from the edge of the traveled way.
- Do not mount with other signs on the same post unless space constraints require it.
4. Standard Sizes and Visibility Considerations
Typical minimum: 48" × 30".
- Choose size based on roadway speed, sight distance, and mounting location.
- Maintain high retroreflectivity for maximum night and adverse-weather visibility.
5. California Notes
Mounted on a Type III barricade or closure across a California roadway, used with advance warning and detour signing to fully close the road.
