Horse riders in Leicestershire have become so fed up with inconsiderate drivers that they have decided to catch them in the act - on film.
Police say they will prosecute if offences are committed
The group, from the Charnwood area, are using a special camera which fixes on to riding hats to film drivers who drive too close to them.
The riders say they can be thrown from their saddles if the horses are spooked by motorists travelling too fast.
Police have said they will take the footage and prosecute where necessary.
Rider Claire Martin, said: "We have had buses and cars coming past very close and people coming past us very fast, not slowing down enough at all.
"We have also had people beeping their horns to get us out of the way."
A spokeswoman from Leicestershire Police, added: "Cars could spook the horses, the horse could bolt and put in danger not just the rider and the motorist but also those who are travelling in the opposite direction.
"We have a responsibility for road safety and we will work with the riders if we have evidence of offences being committed."
