The question of when a person should stop driving, especially large vehicles, has no simple or universal answer. Global studies agree that aging affects crucial driving abilities, such as reflexes, visual and auditory acuity, and cognitive functions. However, establishing a fixed chronological age as a limit is considered unfair and unscientific. The key, as research indicates, lies not in numerical age, but in individual functional capacity. In Europe, and specifically in Spain, legislation has opted for a system that prioritizes continuous evaluation over an automatic ban.

In Spain, the Directorate-General for Traffic (DGT) is clear on this matter: there is no maximum legal age for driving. A DGT spokesperson has explained on several occasions that “age alone is not a determining factor; what matters is psychophysical fitness.” However, the body is aware of the risks associated with aging. Therefore, from the age of 65, the driving license must be renewed more frequently, with the driver undergoing exhaustive medical check-ups that assess precisely those capacities that can diminish with age.

The medical perspective adds an essential layer of understanding to the debate. Geriatricians and ophthalmologists insist that the decline is not homogeneous. A specialist in traffic medicine emphasizes that “at 70, we can find people with the capabilities of someone in their fifties and vice versa.” However, physiological changes are undeniable: the eyes take longer to adapt to glare, the visual field can narrow, and the reaction time to an unexpected event lengthens. For heavy vehicles, where the consequences of an error are potentially more serious, these factors are multiplied, which is why the controls for these licenses are even stricter.

For professional drivers or those who handle large-tonnage vehicles, Spanish regulations are particularly rigorous. From the age of 65, the renewal of the C (trucks) or D (buses) license is mandatory every three years and includes specific tests. DGT experts argue that this frequency is not discriminatory but a proactive safety measure. The goal is to detect in time any condition, such as the onset of dementia or a cardiovascular problem, that could pose a risk when driving a vehicle that, due to its mass and dimensions, requires maximum attention and responsibility. In conclusion, far from recommending a “specific age” to stop driving, the Spanish model and scientific evidence point towards personalized management of driving ability. The answer is not to revoke the license at a certain age, but to promote self-awareness among older drivers and ensure, through periodic and rigorous medical check-ups, that all road users, regardless of their age, meet the necessary requirements for safe driving. It is about balancing personal autonomy with collective responsibility for road safety.
