Belgian authorities have introduced a new road sign featuring a crossed red prohibitive sign circling the words ‘cruise control’ to warn drivers.
Drivers caught using the technology on congested motorways face a E50 (£35) on-the-spot fine or a maximum fine of €1,375 (£964) if they go to court.
Bert Morris, deputy director of the AA Motoring Trust, said: ‘This is the first time a restriction on the use of cruise control has been applied in Europe and follows a series of related accidents on Belgian motorways.
‘The signs are normally used only on motorways and only where the risk of rear-end accidents, due to congestion, is high.
‘The difficulty comes with enforcing the restriction and can only realistically be done following an accident where cruise control is a proven contributory factor.
‘However, UK motorists driving on Belgian motorways need to be aware.’
