Road and traffic signs
The STOP sign has a unique shape that no other sign uses. Why is this shape important?
- It helps the sign reflect light better at night
- It shows the sign belongs to a motorway
- It means the order only applies to large vehicles
- You can still recognise it if snow or dirt covers the writingCorrect
Why?
The STOP sign is the only octagonal (eight-sided) road sign. This special shape means you can recognise it even if snow, mud or dirt covers the word 'STOP'. Rule 171 of The Highway Code says you must stop behind the line at a STOP sign and wait until it is safe before entering the junction.
