The Portugal National Police (PSP) intercepted a 17-year-old girl driving without a license on Estrada da Malveira in Cascais during the early morning hours of August 5, a case that underscores the ongoing challenge of unlicensed driving by minors in Portugal and the significant legal consequences that follow.
Why This Matters
• Criminal offense: Driving without a license is a crime in Portugal, punishable by up to 2 years in prison or fines reaching 240 days worth of daily income.
• Rising trend: The Portugal National Republican Guard (GNR) registered 7,525 unlicensed driving offenses in 2025, a 9% increase from 2024, reflecting an ongoing enforcement challenge.
• Youth at risk: Road traffic accidents are the leading cause of death among Portuguese adolescents aged 13-17, representing nearly 48% of all external-cause fatalities in that age group between 2014 and 2023.
• Family vehicle theft: The car in the Cascais incident was taken without parental consent, a growing concern as vehicle theft overall remains a significant enforcement priority.
What Happened in Cascais
Officers from the PSP Metropolitan Command of Lisbon, operating through the Cascais Police Division, stopped the vehicle at approximately 1:30 a.m. during a routine traffic checkpoint. The teenager immediately admitted she did not possess a driver's license, according to a police statement issued to newsrooms on Thursday.
Three other minors, aged between 16 and 17, were passengers in the car. Verification with the Portugal Institute for Mobility and Transport (IMT) confirmed the driver had never been legally licensed to operate a motor vehicle.
Further investigation revealed the car belonged to the parents of one of the passengers and had been taken without their knowledge or permission. Police returned the vehicle to its rightful owner, who was informed of the circumstances. The teen driver was formally notified to appear before the Cascais Public Prosecutor's Office for her first judicial interrogation.
Legal Consequences for Underage Offenders
Portugal treats unlicensed driving as a criminal offense, not merely an administrative infraction, regardless of the driver's age. The legal framework is unforgiving, especially when minors are involved.
Penalties include prison sentences of up to 2 years or monetary fines of up to 240 days. A conviction generates a criminal record, which can severely impact future employment prospects. Courts may also impose a ban on obtaining a driver's license for a specified period and can mandate completion of road safety education courses before any future license application is considered.
When the driver is a minor, cases are typically referred to Juvenile Court, which can order supervision, fines, and apply protective measures under Portugal's child and youth protection laws. The vehicle used in the offense is subject to seizure.
Insurance implications add another layer of financial risk. If an unlicensed driver causes an accident, insurers may refuse to cover damages, leaving the driver personally liable for all civil and criminal costs arising from injuries or property damage to third parties.
What This Means for Residents
For parents and vehicle owners, this case highlights the importance of securing car keys and monitoring access to family vehicles. Legal responsibility extends beyond the driver: if a minor takes a car without permission, the owner may face scrutiny regarding vehicle security and supervision.
For young people, the message is clear: driving without proper licensing is not a minor traffic violation. It is a criminal act that can derail educational and career opportunities through a permanent record. The minimum legal age to drive in Portugal is 14 for mopeds (category AM, requiring theoretical and practical exams), 16 for light quadricycles (category B1, with parental authorization for those under 18), and 18 for standard passenger vehicles.
Anyone under these age thresholds or without the corresponding license is breaking the law, and enforcement is intensifying. Between the PSP and GNR, Portuguese authorities detained 11,359 unlicensed drivers in 2024 alone, and the trend continues upward.
The Broader Picture: Youth and Road Safety
Road traffic accidents remain the primary external cause of death among Portuguese children and adolescents under 18, with the 13-17 age bracket accounting for nearly half of all fatalities in this category over the past decade. Adolescence is a period marked by risk-taking behavior, impulsivity, and underdeveloped hazard perception, which makes this demographic particularly vulnerable behind the wheel.
Even among legally licensed young drivers, the risk is acute. The Portugal National Road Safety Authority (ANSR) has expressed concern over rising crash rates among drivers aged 15 to 29. Young male drivers are overrepresented in road fatalities, and many of these incidents involve alcohol or drugs.
Vehicle theft and unauthorized use by minors remains a concern. PSP enforcement data shows ongoing efforts to combat motor vehicle theft, which remains a persistent issue affecting Portuguese families and communities. The PSP and GNR regularly detain individuals for vehicle-related offenses, with multiple high-profile cases involving minors.
Incidents involving minors stealing family or acquaintance vehicles are not isolated. In June 2025, three youths aged 16 to 20 stole a car in Almada using a knife. Seven teenagers between 16 and 17 were detained in Lisbon in February 2025 for multiple aggravated robberies involving violence. Another three young suspects were arrested by the GNR in June for a series of robberies across the Guarda and Santarém districts, some involving weapons.
How Authorities Are Responding
The PSP has ramped up both prevention and enforcement efforts. The "Safe Road" operation, integrated into the School Safety Program, conducts awareness campaigns across preschool, primary, and secondary schools throughout Portugal. Since the 2013/2014 academic year, more than 28,000 educational sessions have been delivered, using age-appropriate materials to teach children and teens about road safety, the consequences of traffic violations, and responsible behavior.
These sessions emphasize close interaction between officers and students, aiming to cultivate a culture of safety and compliance before young people reach driving age.
Simultaneously, continuous traffic enforcement operations target unlicensed driving, dangerous maneuvers, and illegal street racing, often promoted via social media. While these operations are not exclusively focused on minors, they contribute to a broader deterrent effect and help dismantle risky driving subcultures that may influence younger audiences.
Key Takeaway
The Cascais case is a stark reminder that unlicensed driving by minors is both dangerous and illegal, carrying severe personal, legal, and financial consequences. For families, vehicle security and supervision are critical. For young people, waiting until legal age and completing proper training is not optional—it is a matter of law, safety, and future opportunity. As enforcement intensifies and youth road fatalities remain high, the stakes have never been clearer.
