Poster warning over illegal taxis in South Derbyshire
A campaign to highlight the risks of using unlicensed taxis has been started by a Derbyshire council.
South Derbyshire District Council said it vetted all approved drivers and tested their vehicles.
Using an illegal cab meant passengers were taking a chance with their own safety, officials said.
Posters are being put in pubs, libraries, supermarkets and clubs telling customers how to identify a licensed vehicle.
Councillor Peter Watson said: "Vehicles that operate illegally without a licence are not monitored or answerable to anyone and the same assurances over standards of service are not in place.
"This campaign will help raise awareness and make it easier for people to ensure they do not put themselves at unnecessary risk."
All licensed private-hire vehicles in the district display a yellow plate on the rear and a smaller internal plate.
Private-hire drivers must also wear an ID badge issued by the council, which includes his or her photograph.
