Assessment of executive functions and attentionEvaluation on a driving simulatorEvaluation on-road
Assessment of executive functions and attention: * Attention Assessment Test (TAP),
* Trail Making Test (TMT), which assesses mental flexibility,
* Stroop Selective Attention Test, assessing the ability to inhibit automatic processes,
* Wisconsin Card Sorting Test (WSCT-modified), assessing abstract reasoning and the ability to change cognitive strategies in response to changes in the environment.
Evaluation on a driving simulator: The 1-hour simulator assessment will be preceded by a 1.5-hour orientation session. The simulator used is the Rehab Evolution, manufactured by Develter Innovation.
Evaluation on-road: The on-road evaluation will be conducted using a dual-control vehicle, with a certified driving instructor and an occupational therapist. The evaluation will last one hour.
Study summary
The primary objective of this study is to compare the number of driving errors made by novice adolescents (0-5 hours of driving instruction) with ASD to those made by neurotypical adolescents during a standardized driving simulator assessment. The secondary objectives of the study are to:
* Compare the visual strategies used by adolescents with ASD to those of neurotypical adolescents during a driving assessment on a simulator.
* Compare the types of errors and driving performance (i.e., speed, reaction time, following distance, and braking distance) of adolescents with ASD to those of neurotypical adolescents during the driving simulator assessment.
* Compare the driving performance of these two groups during a real-world road assessment using the TRIP scale.
* Examine the consistency between driving performance measured in the simulator and that observed in real-world conditions for both groups.
* Compare the anxiety levels of these two groups during driving tests on the simulator and on the road.

Primary outcome measure(s)
Assessment of driving errors in various scenarios using a driving simulator. — At enrollment Each adolescent's driving performance will be measured, following Michon's model, through two distinct levels of assessment:
* Assessment 1 focuses more on the operational level of Michon's model: the participant must control their vehicle while stationary and on the road under simple conditions, i.e., with no other road users and no incidents. During 5 tests, control of the controls, maintaining a straight line and staying in the lane when turning, and maintaining speed at low speeds (50 km/h) and moderate speeds (80 km/h) will be evaluated.
* Assessment 2, which places greater emphasis on tactical skills: The participant will be confronted with more complex situations requiring adaptation of driving to road conditions and other road users. The aim is to gradually introduce additional cognitive demands: visual attention, visual scanning, interaction with other road users, and the management of critical situations in urban and rural environments through six tests.
