The AA is calling for a national lane discipline campaign after new research found that eight out of 10 drivers regularly witness risky lane behaviour on motorways. The findings highlight ongoing concerns about how motorists use multi-lane roads, with common issues including middle lane hogging, undertaking and drivers changing lanes without signalling.
According to the research, 85% of drivers report seeing middle lane hogging, while 80% say they frequently notice undertaking. Nearly four in five motorists also report drivers changing lanes without signalling, and a similar number see last-minute moves across lanes to reach motorway exits. Even in heavy traffic, frequent lane changing remains common, which can increase the risk of sudden braking and near-miss incidents.
Although some behaviours have reduced slightly, poor lane discipline continues to contribute to congestion, driver frustration and increased collision risk. On busy motorways, even small mistakes in lane use can disrupt traffic flow, causing traffic to bunch together and increasing the likelihood of incidents.
The AA believes there needs to be more visible motorway policing as well as clearer public messaging about motorway rules, particularly the guidance to keep left unless overtaking. The organisation says consistent enforcement combined with public awareness would help improve driver behaviour.
Jack Cousens, The AA’s head of roads policy, said: “The fact that eight in 10 drivers report seeing risky lane moves shows that poor lane discipline remains far too common. These behaviours disrupt traffic flow and increase the risk of collisions. We believe it’s time for a renewed national focus on lane discipline, which makes clear that middle lane hogging and careless lane changes are not acceptable.
Having more traffic officers and police in cars acts as a deterrent to poor behaviour and reassures drivers that the rules are being enforced. Lane discipline is fundamental to motorway safety, and better compliance would reduce congestion and cut risk for everyone.”
