Regulatory signs say what you must or must not do, and ignoring them is an offence. These signs protect bridges, tunnels and roads from vehicles that are too heavy, too high or unsuitable.
- Check any height or mass limit before you drive under or over the structure.
- Where a road is signed as unsuitable for certain vehicles, use another route.
