The annual MOT could be replaced by a bi-annual test if government plans to ease the cost of living get the go ahead.
It is widely reported that Transport Secretary Grant Shapps put forward the idea of moving from an annual check to one every two years.
The proposal came in response to a directive from PM for ministers to produce ideas to help with rising inflation and cost of living crisis.
The proposal to change the frequency of MoT is an old chestnut and has been ruled out in the past on grounds of safety.
In 2018 a proposal by the free market Adam Smith Institute for the MoT to be scrapped has come under fire from motor trade bodies. The Institute suggested reforms the government could pursue to cut costs for motorists.
It called for a reduction in the frequency of vehicle safety inspections from annually to every three or five years.
The Independent Garage Association (IGA) said the proposal was dangerous and would increase costs for motorists long-term.
Stuart James, IGA chief executive said: “In our opinion this whole plan is dangerous, unwanted and unreasonable. This proposal has been scrutinised at least four times that I have known of in the last 15 years, and every time it has been deemed detrimental to road safety.
Jack Cousens, head of roads policy at the AA, said: “Though well intended, moving the yearly £55 spend on an MOT to every two years could make costs worse for drivers with higher repair bills, make our roads more dangerous and would put jobs in the garage industry at risk.
“Only recently the government stepped away from switching the MOT to every two years on the grounds of road safety**, while AA polling shows overwhelming support from drivers who like the security that an annual health check provides.
“The MOT now highlights major and dangerous defects too, showing how important it is to keep cars in a safe condition.
