Other plans include criminal checks for driving instructors

The maximum MoT fee will increase by 14% next month to �50.35. The rise was first announced earlier this year.

The Driving Standards Agency (DSA) is considering adding new questions to the written driving test, which would make the cost rise from �21.50 to �28.50.

Other proposals under consideration include raising practical driving test fees for motorcyclists.

The increase would be from �58 to �60.

It has also been suggested that driving instructors undergo criminal history checks.

The MoT increase comes after the test fell foul of computer problems in recent months.

Following the announcement of the MoT fee rise, Shadow transport secretary Chris Grayling said: "I suspect that the reason these fees have gone up is to pay for yet another government computer system mess up.

"But the people who pay the price are the people on low incomes who often depend on older cars and therefore need to get them tested more frequently."
