Motorists planning to drive into Greater Manchester have reported receiving Clean Air Zone (CAZ) charge warnings on Google Maps - four years after proposals to introduce a restricted area in the city region were scrapped.
After searching for their destination, Google Maps users are given information about a CAZ that has never existed.
The alert warns drivers that restrictions are in place all day, every day for taxi and private hire vehicles, with non-compliant vehicles subject to a daily £10 charge. It also contains a link to an article, published in 2021, providing more details about how the scheme works.
The BBC understands Google is aware of the issue and is rolling out a fix.
In 2015, the UK's Supreme Court ordered ministers to take immediate action to cut air pollution.
Greater Manchester's response was drawn up in 2019, shortly after a government report proposed the introduction, from 2023, of a daily charge for users of high-polluting buses, lorries and taxis.
While some cities - including Birmingham and London - did introduce a charge, there was considerable dissent in Greater Manchester.
Plans to introduce a fee were first suspended and then scrapped by the city region's mayor, Andy Burnham.
This was accepted by Transport Secretary Heidi Alexander, who indicated the decision on whether to introduce CAZ restrictions was a matter for "local leaders, based on what's best for their local areas".
Currently, however, the Google Maps warning reads: "Restrictions are active from Monday to Sunday (00:00-24:00).
"Taxi and private hire vehicles with a petrol engine that doesn't meet at least the EURO 4 standard or vehicles with a diesel engine that doesn't meet at least the EURO 6 standard need to pay up to £10 per day to enter."
A ringfenced area, highlighting Greater Manchester in blue, displays the proposed CAZ charging zone to Google Maps users.
The warning also contains a link to an article first published by Manchester World in 2021 - updated in 2022 - entitled "Seven things you need to know about Greater Manchester Clean Air Zone".
