What does BS 8442 - Miscellaneous road traffic signs cover?
BS 8442 on miscellaneous road traffic signs specifies requirements and tests for rigid and flexible portable signs, barriers, self-supporting portable signs, “Stop/Go” and “Stop/Works” signs, school crossing patrol signs, flat traffic delineators, flap signs, pedestrian crossing and refuge beacons, internally illuminated posts, twin amber flashing light units, non-retroreflecting road studs and retroreflective self-righting bollards.
NOTE: The tests given in BS 8442 are suitable for both initial type testing and production testing. Non-retroreflecting road studs incorporating an active light source are not covered by this standard.
Why should you use BS 8442 - Miscellaneous road traffic signs?
This “catch-all” revised standard on miscellaneous road traffic signs:
- Enables the manufacture of compliant road traffic signs not included in other European or British Standards
- Produces signs that are easily understood by road users and thereby contribute to road safety
- Simplifies the efficient production of standardized signs
- Widens the choice of retroreflective materials from which compliant retroreflective signs can be constructed
- Makes additional improvements that increase the safety of road traffic signs for road users
- Aligns with the government’s highway furniture decluttering initiative
- Helps manufacturers enter new markets and develop their expertise
- Increases confidence in road signs and strengthens risk management
- Can be used as a foundation for accelerated innovation in road sign manufacture
BS 8442 contributes to UN Sustainable Development Goal 9 on industry, innovation and infrastructure.
What’s new about BS 8442 - Miscellaneous road traffic signs?
This is a revision of BS 8442:2015. The major change in BS 8442 is the addition of colour requirements for yellow prismatic retroreflective sheeting.

- References to lower performance for digital printing has been removed now the technology is fully up to the standard of other methods
- The Belisha Beacon Halo and other conspicuity aids are specified to avoid confusion to road users
- Optical performance of school crossings and beacons are updated
- The references to IP ratings of bollards are updated
