Vehicles may only need to have an MOT test every two years under proposals being considered to ease the cost of living crisis.
Boris Johnson has asked cabinet ministers to come up with “innovative” solutions as families are hit by rising taxe and hikes to energy bills.
Government sources told the BBC that transport secretary Grant Shapps has proposed scrapping the requirement to have an annual MOT.
It could see the average car driver save up to £54.85 or £29.65 for a motorbike.
However, motoring groups have criticised the plans and suggested they could lead to safety fears on British roads.
RAC head of policy Nicholas Lyes said: “The purpose of an MOT is to ensure vehicles meet a basic level of safety for driving on our roads.
“Shifting it from annually to every two years would see a dramatic increase in the number of unroadworthy vehicles and could make our roads far less safe.”
A Cabinet minister also pointed out to the PM that less efficient cars burn more fuel, according to Sky News.
But another told the Telegraph that the move was a “bread and butter policy that shows that the Conservatives are on your side”.
Stuart James, chief executive of the Independent Garage Association (IGA), told Car Dealer Magazine: “In times of economic hardship, it’s known that drivers cut back on servicing their cars and it’s the annual MOT that has kept the UK’s road safety at high levels thanks to the vital safety checks it carries out.
“In our opinion this whole plan is dangerous, unwanted and unreasonable.”
Downing Street said the cabinet had discussed a “number of ideas” to ease the pressure on households, including lowering the legal limits on adult supervision for children.
A No 10 spokesperson said the prime minister would chair a “domestic and economic strategy committee” in the “coming weeks” but suggested no new money would be provided to ease the pain for families.
He told reporters: “Certainly, the budgets for departments are set and there are no plans to go outside what’s been agreed.”
Labour leader Sir Keir Starmer said he wants to see “an emergency budget, not a Cabinet meeting” to address the cost-of-living crisis.
