Underage Wheels: Unpacking the Risks of Adolescent Driving in Brazil
"New research sheds light on the prevalence and factors behind underage driving in Brazil, revealing why this risky behavior demands urgent attention."
Driving is a rite of passage for many, but what happens when young people get behind the wheel before they're legally allowed? In Brazil, the issue of adolescent driving is a significant concern, with potentially life-threatening consequences. Understanding the scope of the problem and the factors that contribute to it is the first step toward creating safer roads for everyone.
Transport accidents are a leading cause of death for young people worldwide. In Brazil, land transport accidents are the number one killer of women aged 10-19 and the second leading cause of death for men in the same age group. Studies show that unlicensed drivers are more likely to be involved in accidents, often due to inexperience and risky behaviors.
This article delves into the findings of a recent study that examined the prevalence of underage driving among Brazilian students and the associated risk factors. By understanding the factors, we can work toward effective policies and interventions to protect young people and the wider community.
Teen Driving Safety and Intervention Limits
An integrative review published in 2019 examined rigorous evidence on teen distracted-driving interventions to inform the development of an educational intervention. It reported that interventions to date aim to improve teen and societal safety, but few had achieved effectiveness, highlighting a need for evidence-based approaches. The National Transportation Safety Board reports that over the 10 years covered by its summary, teen drivers averaged less than 7 percent of the driving population but accounted for more than 13 percent of drivers involved in deadly crashes.
Behind the Wheel Too Soon: How Big Is the Problem?
A 2012 study called the National Adolescent School-based Health Survey (PeNSE) offers a revealing snapshot of underage driving in Brazil. The survey looked at students under 18 and found that a significant percentage had driven a motorized vehicle (cars, motorcycles, or boats) in the 30 days before the survey.
- Age Matters: As students get closer to the legal driving age, the likelihood of them driving increases.
- Gender Gap: Boys are significantly more likely to drive than girls.
- Regional Differences: Underage driving is more common in the North and Northeast regions of Brazil.
Brazilian Traffic Mortality Research
A Brazilian study set out to analyze road-traffic-accident mortality from 1996 to 2015, focusing on people aged 10–29. The listed source identifies its scope and period but does not provide its findings in the supplied summary. The other listed records concern older drivers in Brazil, decision-making among older adults in Belo Horizonte, and a U.S. review of adolescent driving; they do not provide additional findings about Brazilian adolescent driving.
Skills, Experience, and Enforcement
The National Transportation Safety Board says motor-vehicle crashes are a leading cause of death for teens and attributes teen drivers’ disproportionately high fatal-crash rate mainly to limited skills and experience. It identifies speeding, distracted driving, and drowsy driving among the risky behaviors. A 2025 opinion article about unlicensed teen driving describes the problem as a systemic failure involving parental neglect, weak enforcement, and inadequate civic education, but its supplied summary concerns a different jurisdiction and does not establish that assessment for Brazil.
Peer Influence and Impaired Driving
A 2019 Frontiers study used simulated driving to examine how social exclusion versus inclusion and peer passengers’ risk-accepting versus passive norms affected risky driving by teenage boys and girls. The supplied summary describes the research question and experimental setup but does not report the results, so it cannot establish which conditions increased risk. A separate American Bar Association article discusses concerns and risks associated with impaired driving by teens and young adults below the legal age to purchase or consume alcohol; neither source provides a Brazil-specific comparison.
Road Safety Starts Now: How Can We Protect Young Drivers?
The PeNSE study underscores the need for a multi-pronged approach to tackle underage driving in Brazil. Simply telling young people not to drive isn't enough. We need to address the root causes of this behavior and create a culture of road safety.
Predicting Risk and Changing Travel Patterns
Research reported by the Annenberg Public Policy Center found that driving skills measured at licensure on a virtual driving assessment featuring common crash scenarios helped predict crash risk. The supplied summary does not give details about the assessment’s predictive accuracy or its application in Brazil. Separately, Brookings reports that young adults have become less likely to have access to a vehicle in their household, a trend that has prompted speculation about a less car-centric urban future.
Safety Restrictions and Access to School and Work
A Pennsylvania State University source says drivers aged 16–19 are nearly three times more likely than older drivers to be in a deadly car accident and notes that alcohol plays a devastating role in many such crashes. Research summarized by CEPR reports that targeted restrictions on teenage drivers were followed over time by larger crash reductions and fewer first-year drivers caught violating the restriction. A Federal Reserve Bank of Philadelphia article notes that graduated driver licensing laws can affect teens’ access to school and employment, making the effects of automobile-specific mobility restrictions on human-capital accumulation ambiguous.
Distraction, Restrictions, and Family Advocacy
A 2025 Harvard Gazette report says a new study found that 7 in 10 young people use cellphones while driving and notes that hundreds of people die each year in crashes involving distracted teen drivers. An NBER Digest summary reports that Australia’s ban on late-night and early-morning driving by first-year drivers reduced crashes and fatalities, with benefits continuing in later years. In another Australian case, the parents of Jordan Hayes-McGuinness—who drove under the influence of alcohol and cannabis in a 2012 crash that killed five young people—have campaigned to change youth driving culture.
The study identified several factors that contribute to underage driving, including:
<ul><li><b>Socioeconomic factors:</b> Students from families with higher maternal education and those who own a car or motorcycle are more likely to drive underage.</li><li><b>Regional disparities:</b> Underage driving is more prevalent in the North and Northeast regions, possibly due to limited access to public transportation and less stringent enforcement of traffic laws.</li><li><b>Risky behaviors:</b> Underage drivers are also more likely to consume alcohol and not use seatbelts, compounding the risks.</li></ul>
