Middle lane hogging on UK motorways is a criminal offence that can land drivers with a £100 fine and three penalty points, the RAC has warned as police forces step up enforcement of lane discipline rules.
The Highway Code requires drivers on motorways and dual carriageways to use the left-hand lane unless overtaking. Once overtaking is complete, drivers must return to the left lane when safe to do so. Staying in the middle lane when the left is clear constitutes an offence under careless driving laws.
The practice creates serious safety risks beyond mere frustration for other motorists, according to the RAC. Middle lane hoggers force overtaking vehicles to cross two lanes into the outside lane and back again, creating unnecessary manoeuvres and potential hazards. The behaviour also triggers tailgating as drivers grow impatient behind slower-moving middle lane traffic.
Police forces nationwide have authority to issue on-the-spot penalties for the offence. Whilst officers may issue verbal warnings for minor instances, fixed penalty notices are increasingly common. In serious or persistent cases where driving significantly impacts other road users, police can pursue prosecution leading to higher fines and additional penalty points.
The RAC's warning comes as millions of UK commuters rely on motorways daily, making efficient traffic flow critical for the national transport network. The organisation hopes clearer guidance on legal obligations will improve lane discipline and reduce the safety risks posed by poor motorway driving habits.
