Portugal petition sparks debate on age limits for drivers – what can the UK learn?

A petition submitted to Portugal’s Assembly of the Republic is reigniting a long-standing debate in road safety policy: should age alone determine whether someone is fit to drive?

The proposal calls for a blanket ban on drivers aged 75 and over, arguing that advancing age is often linked to reduced physical and cognitive ability, including slower reaction times and diminished attention.

While the suggestion has drawn attention across Europe, it also raises important questions for the UK  road safety sector.

The Portugal proposal – safety vs independence

Supporters of the petition claim that age-related decline can increase accident risk and justify stricter controls.

However, critics argue the proposal is overly simplistic. Evidence and public reaction suggest that ability varies widely between individuals, with many drivers over 75 remaining fully capable behind the wheel.

Portugal already operates a system of increased oversight for older drivers, including more frequent licence renewals and mandatory medical certification. This has strengthened arguments that targeted assessment, rather than a fixed age cut-off, may be a more proportionate approach.

The debate highlights a broader tension familiar to the automotive and testing industry: balancing road safety with personal mobility and independence.

What does the UK currently do?

The UK takes a notably different stance. There is no upper age limit for driving.

Instead, drivers must:

• Renew their licence at age 70
• Continue renewing every three years thereafter
• Self-declare that they are medically fit to drive

Additional medical conditions must be reported to the Driver and Vehicle Licensing Agency (DVLA), which can require further assessments or revoke licences if necessary.

Unlike the proposed Portuguese ban, the UK system is built around ongoing individual responsibility and medical oversight, rather than an automatic prohibition based on age.

Age vs ability: where should policy focus?

The Portuguese petition has sharpened a key policy question:

Should road safety rules be based on age thresholds, or on individual fitness to drive?

Arguments for age-based limits

• Simpler to enforce
• Reflects general trends in declining reaction times and cognition
• May reduce risk in higher-age groups

Arguments for individual assessment

• Recognises wide variation in health and capability
• Avoids discrimination and “one-size-fits-all” rules
• Maintains independence, particularly in rural areas
• Aligns with existing UK frameworks

Critics of age bans also point out that collision data in many countries often shows higher risk among younger drivers, particularly those aged 18–24, due to inexperience and risk-taking behaviours.

Should the UK have this debate?

The UK already leans strongly toward an individual fitness model, but the Portuguese petition shows that the issue is far from settled internationally.

With an ageing population and increasing pressure on road safety, the question is likely to resurface:

• Is the current UK self-declaration system robust enough?
• Should there be more formal testing beyond a certain age?
• Or would fixed age thresholds undermine fairness and independence?

The bottom line

Portugal’s proposed ban on over-75 drivers has sparked a wider European conversation, one that challenges policymakers to balance safety, fairness, and freedom.

For the UK, the key takeaway is clear: age alone may be an imperfect measure of driving ability.
