The Tories have pledged to reverse Sadiq Khan’s ultra low emisson zone (ULEZ) expansion if Rishi Sunak wins the general election.
The party said it would introduce legislation setting out a series of measures to back motorists.
They include scrapping the ULEZ expansion to outer London, as well as banning pay-per-mile road taxes and giving residents the right to referendums on Low Traffic Neighbourhoods (LTNs) and 20mph zones.
Prime Minister Rishi Sunak said: “We are the party on the side of drivers. That’s why we have a clear plan to keep motoring costs under control and ensure people have the freedom to drive as they need to lead their daily lives.
“We will empower drivers and local residents to challenge aggressive and punitive traffic-inducing measures, like LTNs that were imposed without local consent.
“That’s the clear choice in this election – between Labour who have launched a war on drivers in London and Wales, and our clear plan to give drivers the freedom they need to build a secure future for themselves and their children.”
The Backing Drivers Bill would be introduced in the first King’s Speech if the Conservatives stay in power.
Transport Secretary Mark Harper added: “We will continue to build on our clear plan for drivers and make sure they are supported in the face of Labour politicians desperate to tax them off the roads.
“We will reverse Sadiq Khan’s unfair ULEZ expansion and rule out any blanket 20mph zones because we are on the drivers’ side.
“And we will rule out any pay-per-mile road tax to keep costs for drivers down.
“There’s a clear choice at this election – Labour who will continue to penalise drivers or the Conservatives who will back drivers.”
Mr Khan, the Labour Mayor of London, sparked a backlash over his expansion of the ULEZ to cover the whole of the capital last August.
Meanwhile, the Labour-run Welsh Government prompted widespread fury with a 20mph default speed limit in built-up areas introduced last September.
