The Traffic Signals Ahead Temporary road sign (TW301) is a temporary W Series warning sign used to alert drivers that traffic signals are ahead. It is typically deployed where signal operation is newly introduced, temporarily reinstated, or where advance warning is required for traffic management.
Purpose and function

Typical applications
- Roadworks and temporary traffic management zones
- Approaches to temporary or newly commissioned signals
- Intersections with limited visibility or higher speed approaches
- Event traffic control and short-term lane changes
Permanent counterpart
If you need a permanent version, use the Traffic Signals Ahead road sign (W301).
Commonly used with
- Traffic Control “Stop” Ahead road sign (W302)
- Traffic Control “Yield” Ahead road sign (W303)
