Moped owners in a London borough are being given the chance to take a free riding test in an attempt to cut noise.
The first free bike tests take place on Wednesday
Westminster City Council said riders were causing accidents as well as disturbing people living in the area.
It decided to pay for the Compulsory Basic Training (CBT) test for riders who began to drive more courteously, rather than banning them from the area.
Persistently bad drivers can have their bikes confiscated by police. The first free tests take place on Wednesday.
Westminster says complaints about moped noise has dropped since it started an information campaign to tell inexperienced riders about the scheme.
Councillor Danny Chalker of Westminster said: "The riders have responded fantastically since we began the information campaign in Queen's Park.
"The number of reported noise incidents has declined dramatically.
"It seems that some moped riders simply hadn't realised the disturbance created by the noise of their bikes.
"As soon as they found out, they toned their riding down."
The first moped riders will be taking their CBT under the scheme in Edgware.
