WAIT ON STOP - GO ON SLOW Sign Requirements

1. When a WAIT ON STOP - GO ON SLOW Sign Is Used

Instructs road users at a flagger station to wait when the flagger displays STOP and proceed slowly when the flagger displays SLOW.

• Flagger stations on one-lane, two-way control
• Used with the STOP/SLOW paddle (W20-8) and Flagger (W20-7)
• Alternating one-way flagging operations

2. How and Where It Applies

In the field, R1-7a Wait on Stop - Go on Slow is typically positioned at the advance warning area, ahead of the work. Common deployments include flagger stations on one-lane, two-way control; used with the STOP/SLOW paddle (W20-8) and Flagger (W20-7); alternating one-way flagging operations. 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 R1-7a advance warning area, ahead of the work.

• 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: 24" × 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

Posted at a California flagger station to reinforce how drivers must respond to the STOP/SLOW paddle, used with the flagger operation in a one-lane, two-way TTC setup.

6. Common Field or Planning Mistakes

• Temporary regulatory control not warranted or conflicts with existing control.
• Reduced speed limit posted without proper speed-setting authorization.
• Wrong-way protection (DO NOT ENTER / WRONG WAY) missing at closed approaches.
• Sign size not appropriate for the facility.
