Motorists over the age of 75 face compulsory tests of their eyesight and ability to drive under proposals being considered by ministers．

The biggest overhaul of motoring law in a generation could also lead to all drivers having to give assurances（保证） of their fitness to get behind the wheel every 10 years．

Other changes under consideration include issuing（发放） daylight driving licenses for motorists with night blindness, together with stricter checks on all drivers whose medical condition brought a threat to other road users．

It is understood that the proposals will be part of a review of the law governing the medical fitness of drivers that will be announced publicly by the summer．

The Driver and Vehicle Licensing Agency is dealing with a rising number of motorists who are concerned that they have conditions---from failing eyesight to epilepsy---that could affect their driving．

In 2006, the DVLA dealt with 600,000 motorists whose physical ability to drive needed to be recertified（重新认证）, a 20 per cent rise on the previous year． With an ageing population, the biggest challenge is dealing with the rising number of elderly motorists． By 2021, there will be an estimated three million drivers over the age of 70 on Britain’s roads．

Drivers must renew their licenses at the age of 70 and every three years thereafter． The applicant is legally required to tell the DVLA of any conditions that could weaken their ability behind the wheel．

Ministers have ruled out a compulsory maximum age for driving but will instead rely on tightening up the checks on motorists over the age of 75． The most likely option would be tests to ensure motorists were fit to drive． They would include an eyesight test and a cognitive（认知） test that would prove a driver's ability to react to road signs, driving conditions, pedestrians and vehicles．

However, checks are likely to be tightened at all ages． The strictest controls are expected to be imposed（强制） on motorists of any age who have had a heart attack or stroke． They could have to produce a doctor's approval to resume（重新得到） driving． Anyone making a false declaration would be guilty of a criminal offence．
