A campaign to put the brakes on bogus taxi drivers has got under way in North East Lincolnshire.
Hundreds of posters and beer mats have been printed to make sure revellers can tell which taxis are unlicensed.
The move is part of a campaign by North East Lincolnshire Council to ensure the safety of partygoers in the borough.
The council will also be working with Humberside Police to raise awareness of drink spiking and handing out 10,000 bottle toppers in pubs and clubs.
TIPS FOR SAFE TAXI JOURNEYS
Check the cab has a taxi registration plate on rear bumper
Ask to see the driver's identity badge
Check for signs identifying which company the taxi comes from
Ask the taxi company the name of the driver when you book and check it
The council's community safety and Hackney licensing officers, local newspapers and licensees are taking part in the campaign.
Council leader Andrew De Freitas said: "People shouldn't be getting into non-licensed taxis or private hire cars, or those which are not displaying taxis signs.
"Anyone using taxis or private hire cars on a night out should ask the driver for identification before getting into a vehicle, and it's a good idea, particularly for women on their own at night, to text the registration of the taxi to a friend before getting in."
