Regulatory sign
No overtaking sign
What does the No overtaking sign mean?
You must not overtake from this sign until you pass a sign that cancels the restriction.
Also known as: No overtaking sign
What it means
Overtaking is prohibited along the stretch of road that starts at this sign.
The restriction continues until you pass a sign that cancels it, so stay behind slower traffic even if the road ahead looks clear.
Where overtaking isn't banned, the Highway Code still lists places where you shouldn't, such as approaching a junction, where the road narrows and at a level crossing.
Rules to know
You must not overtake after a 'No Overtaking' sign until you pass a sign cancelling the restriction.
The Highway Code, Rule 165
Don't overtake where you might come into conflict with other road users, for example approaching a junction, where the road narrows or at a level crossing.
The Highway Code, Rule 167
Common mistakes
Mistake: Overtaking once you can see the road ahead is clear.
Instead: The ban continues until a sign cancels it, whatever you can see.
