ONE DIRECTION LARGE ARROW (RIGHT) Sign Requirements

1. When a ONE DIRECTION LARGE ARROW (RIGHT) Sign Is Used

The W1-6R One Direction Large Arrow (Right) sign is a horizontal warning sign with a single large arrow that directs traffic to turn or bear right at a sharp change in roadway alignment. It is mounted on the outside of the curve or turn, facing approaching drivers, so the arrow points in the direction the road goes.

• Mounted on the outside of a sharp right change in horizontal alignment
• Used to guide traffic around a curve, turn, or work-zone diversion to the right
• Sized and placed per the CA MUTCD and the roadway type

2. How and Where It Applies

In the field, W1-6R One Direction Large Arrow (Right) is typically positioned at the on the outside of a sharp change in horizontal alignment, facing approaching traffic. Common deployments include mounted on the outside of a sharp right change in horizontal alignment; used to guide traffic around a curve, turn, or work-zone diversion to the right; sized and placed per the CA MUTCD and the roadway type. 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 W1-6R on the outside of a sharp change in horizontal alignment, facing approaching traffic.

• 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" × 24" on conventional roads; 60" × 30" on expressways and freeways.

• Choose size based on roadway speed, sight distance, and mounting location.
• Maintain high retroreflectivity for maximum night and adverse-weather visibility.

5. California Notes

W1-6R One Direction Large Arrow (Right) is used in California per the CA MUTCD at sharp changes in alignment and around work-zone diversions.

6. Common Field or Planning Mistakes

• Sign not shown at the correct advance distance for the posted speed.
• Advance warning sign missing or out of sequence on the TCP.
• Wrong size specified for the roadway classification (conventional vs. expressway).
• Sign sheeting / retroreflectivity class not noted on the plan.
