Fitness to drive is defined by minimum medical standards set by the DVLA. A driver may feel broadly well, function normally day to day, and still fall outside the DVLA’s medical standards without realising it. From a road safety perspective, this creates a legal risk that exists long before it becomes visible.
According to the Office for National Statistics, around 32% of UK adults have high blood pressure, yet nearly 30% of those remain undiagnosed. That’s 4–5 million people in England alone – many of whom may be behind the wheel every day.
