The Slippery Road Temporary road sign (TW333) is a W Series warning sign used to alert drivers that the road surface ahead may be slippery. It is used during temporary conditions such as roadworks, surface treatments, spills, seasonal mud or sand, or temporary drainage issues.
Purpose and function
This sign provides advance warning so drivers reduce speed and adjust driving behaviour to maintain control. It supports safer stopping, smoother steering, and reduced skid risk where traction is temporarily compromised.
Typical applications
- Roadworks where loose material, wet tar, or temporary surfacing increases skid risk
- Temporary hazards such as oil, diesel, or chemical spills
- Sections affected by mud, sand, or standing water after storms
- Temporary diversions with reduced traction or uneven surfaces
Permanent alternative
Commonly used with
- Roadworks ahead Temporary road sign (TW336)
