The No Abnormal Vehicles road sign (R233) is a regulatory prohibition sign used to indicate that abnormal vehicles, including oversized or overmass vehicles requiring special routing or permits, are not permitted beyond the sign.
Purpose and function

Typical applications
- Routes with height, width, or turning constraints
- Bridges, underpasses, and restricted structures
- Urban or estate roads with limited manoeuvring space
Temporary alternative
A temporary version is available where restrictions apply for a limited period:
