Middle Lane Hogging: Common, Illegal, Barely Enforced
Last checked
Middle lane hogging is reliably near the top of every list of things that annoy British drivers, and about a third of us admit to doing it. It has been a specific offence for over a decade. Almost nobody is ever fined for it.
The Rule
Rule 264 of the Highway Code is one line long: keep in the left lane unless overtaking, and when you have overtaken, return to the left lane when it is safe to do so. Rule 137 says the same for dual carriageways.
Sitting in the middle lane with an empty inside lane is not a grey area. It reduces a three-lane motorway to two, pushes other traffic into undertaking manoeuvres that are themselves unsafe, and in heavy traffic it is one of the reasons queues form where there is no obstruction at all.
The Penalty
Since 2013 the police have been able to issue a fixed penalty notice for careless driving, which covers lane hogging and tailgating: £100 and three penalty points, on the spot. That figure has not risen since it was introduced. More serious cases go to court, where the fine can be far higher and the points can reach nine or a ban.
How Common It Is
National Highways research with Ipsos found 32% of drivers admit to middle lane hogging at least occasionally, and 34% had seen it on their most recent journey. Nearly a quarter admitted to tailgating, and around three-quarters thought both behaviours were likely to cause collisions.
So this is not a minority of bad drivers. It is roughly one in three of us, and most people doing it do not think of themselves as doing anything wrong.
The Excuse, And Why It Does Not Hold
Drivers say they feel safer in the middle lane — away from vehicles joining at junctions, away from stopped cars on the inside, away from the constant moving in and out. On a busy motorway with traffic entering every few miles, staying out is genuinely less work.
The counter is simply that the road is not designed for it. And since learner drivers have been allowed to take motorway lessons with an instructor since 2018, the old excuse that nobody was ever taught motorway discipline is running out.
Will Cameras Catch It?
Probably, eventually. Camera systems that detect tailgating have been trialled in England — a two-month trial on the M1 in Northamptonshire identified around 26,000 tailgating incidents, and a further trial ran in Warwickshire. But those trials sent warning letters, not fines, and there has been no national rollout. As things stand in 2026 the technology remains at trial stage.
For now the most effective enforcement is other drivers with dash cams submitting footage, which is how a great deal of lane discipline and tailgating evidence now reaches the police.
One Thing That Has Changed
New smart motorways are no longer being built — the programme was cancelled in 2023, with money redirected to safety improvements on existing all-lane-running stretches, including additional emergency areas and stopped-vehicle detection. Those existing stretches remain, so on many motorways the inside lane is a live traffic lane with no hard shoulder.
That makes lane discipline more important, not less. If a vehicle is stopped in the left lane ahead, the drivers who move over calmly and in good time are the ones who have been checking their mirrors — not the ones who have parked in the middle lane for the last twenty miles.
