Introduction
Learning to drive is a key step in the transition to adulthood. However, driving is a complex task that depends on abilities such as attention, memory, and motor skills, all coordinated by executive functioning. Neurodevelopmental disorders (NDDs), such as ADHD or ASD, can make driving challenging, though the severity of difficulties varies, resulting in different challenges during the licensing process. However, it remains unclear how many individuals with NDDs obtain a driver's license and which factors may influence this outcome.


Purpose
The aim of the study is to examine how NDDs affect the ability to obtain a driver's license and how individuals with various NDDs perform on driving test. The specific research questions are:
• How prevalent are NDDs among young drivers?
• What differences are there in driving test outcomes between individuals with NDDs and those without?"


Method
The study is conducted as a retrospective design utilizing linked data from national registers. The data collection has ethical approval and includes information from the National Board of Health and Welfare's patient register, the Swedish Transport Administration's theory and practical driving tests, and background data from Statistics Sweden. The study population consists of individuals who, between 2000 and 2022, received a NDD diagnosis (ICD-10) before the age of 18. A control group is matched on year of birth, sex, and municipality of residence.


Results
Data collection is complete, encompassing over 300,000 individuals with NDDs and a matched control group. Data analyses are planned to commence shortly.


Conclusions
This study will highlight the challenges faced by young drivers with NDDs during the driver licensing process. The results will provide insights that can inform the development of driver education and assessment systems that are accessible and fair for all learners, as well as guide future research and policy to better support this growing population.
