Motorists are being warned they face invalidating their car insurance policies if they fail to make necessary repairs to their cars.
A survey by motoring website and magazine Auto Trader found that 51% of motorists are concerned about paying for repairs found during an MOT inspection because of the recession. As a result, 32% of motorists are putting off getting repairs done, leading to an increase in potentially unroadworthy vehicles.
A total of 15% of the repairs being put on hold are deemed to be "quite major", with 5% "very major".
Figures also show that 10% of drivers are delaying putting their car through an MOT test until after its due date to avoid paying out money before they really need to.
Auto Trader marketing director Matt Thompson said: "It is extremely worrying that nearly half of all UK motorists are prepared to drive around in an unroadworthy vehicle to try and save money during these difficult times.
"We believe that motorists on the whole are very responsible, but with tightening budgets and possible job losses looming, motorists are being very careful with their money and feel that they have no option but to sacrifice essential vehicle maintenance."
