A private hire driver has been issued a defect notice from Merseyside Roads Policing Unit for failing to display 'No Smoking' signs on the vehicle's windows.
All hackney carriage taxis and private hire vehicles up and down the country are required by law to display 'No Smoking' signs clearly for all passengers to see.
The driver, who is from Coventry, but licensed by Wolverhampton City Council, was stopped by officers late on 12 September.
Merseyside Roads Policing Unit have been conducting taxi and private hire safety checks intensely over the last few weeks and have warned drivers that any that are licensed from other authorities will be expected to meet certain standards.
A spokesperson for the force said: "We are continuing our taxi safety operation. Any taxis visiting from other areas will be expected to have the same high standards of safety as our Merseyside vehicles."
