As people get older, their bodies gradually change. Some of these changes can affect your ability to drive, such as slower reaction times, weaker eyesight or weaker muscles.
Some changes – such as your eyesight – can be measured and there are legal limits to make sure you are safe to drive: see GOV.UK for information about the eyesight rules. Other changes are harder to judge but if you notice your reactions becoming slower, for example, you may need to think about whether you should stop driving. If you’re not sure, speak to your doctor.
