Highway chiefs have been criticised by a police accident investigator for erecting wooden screens to stop motorcyclists seeing traffic as they approach a roundabout.
The screens are in the middle of a dual carriageway to force motorcyclists to slow down more before entering the roundabout, but critics say they will also hide bikers from car drivers.
They have been installed on the A31 in Cadnam, Hampshire, after residents complained of bikers calling it the ‘Cadnam GP circuit’ on internet forums.
Gary Baldwin, an accident investigator and advanced riding instructor, said: “It’s bonkers. The earlier we can see each other, the earlier we can make adjustments to what others are doing.”
Hampshire County Council has also put up signs saying ‘Bikers Think!’ – a reversal of the traditional ‘Think Bike!’ message.
Councillor Mel Kendal said: "Residents and local businesses have reported to me that they support the moves we are taking and are glad their concerns have been raised."
