Driving behaviors in adults with autism spectrum disorders.

Daly et al. (2014) · Journal of autism and developmental disorders 2014
★ The Verdict

Adults with autism who drive rack up more tickets and crashes, so screen early and target maneuver practice, not more rule memorization.

✗ Skip if Practitioners serving clients under 15 or non-driving populations.

01Research in Context

01

What this study did

Researchers asked licensed drivers with autism about their real-world driving. They compared answers to drivers without autism.

People filled out surveys on crashes, tickets, and trouble they felt behind the wheel.

02

What they found

Drivers with autism said they had more accidents, more tickets, and more worries while driving. The differences were small but steady.

03

How this fits with other research

Chee et al. (2017) watched the same groups on actual roads. They saw the same struggles with tricky moves, yet found drivers with autism followed traffic rules better. Self-report and on-road data line up: maneuvers are the weak spot, not rule knowledge.

Reimer et al. (2013) ran a driving simulator one year earlier. Heart rate and eye-tracking showed stress and different gaze patterns under load. The 2014 survey findings now confirm those small simulator signs show up as real tickets and crashes on the street.

Anthony et al. (2020) tested brand-new drivers. Simulator errors and anxiety were large; on-road gaps were smaller. Together the studies map a path: start with anxiety control and cognitive load practice, then move to quiet roads.

Why it matters

Transition plans often skip driving. This paper says you should ask about it. Add two questions to your intake: "Have you had tickets or crashes?" and "Do you feel stressed while driving?" If the answer is yes, link the client to a driver specialist who can rehearse maneuvers and coping skills before more violations or accidents pile up.

03Original abstract

This pilot study investigated driving history and driving behaviors between adults diagnosed with autism spectrum disorders (ASD) as compared to non-ASD adult drivers. Seventy-eight licensed drivers with ASD and 94 non-ASD comparison participants completed the Driver Behavior Questionnaire. Drivers with ASD endorsed significantly lower ratings of their ability to drive, and higher numbers of traffic accidents and citations relative to non-ASD drivers. Drivers with ASD also endorsed significantly greater numbers of difficulties on the following subscales: intentional violations, F(1, 162) = 6.15, p = .01, η p (2)  = .04; mistakes, F(1, 162) = 10.15, p = .002, η p (2)  = .06; and slips/lapses, F(1, 162) = 11.33, p = .001, η p (2)  = .07. These findings suggest that individuals with ASD who are current drivers may experience more difficulties in driving behaviors and engage in more problematic driving behaviors relative to non-ASD drivers.
