Yes, driving is classified as an instrumental activity of daily living (IADL). It falls under the broader category of “transportation” or “community mobility” in the standard scales used by healthcare professionals to assess how well someone functions independently. Unlike basic ADLs such as bathing, dressing, and eating, driving requires complex thinking, sensory processing, and physical coordination working together in real time.
Where Driving Fits in the IADL Framework
The most widely used tool for measuring IADLs is the Lawton-Brody Instrumental Activities of Daily Living Scale, developed for geriatric assessment. It doesn’t list “driving” as a standalone item. Instead, it uses the category “Mode of Transportation,” which is scored on a five-point scale ranging from full independence (driving your own car or using public transit alone) down to not traveling at all. Driving your own car represents the highest level of transportation independence on this scale.
The American Occupational Therapy Association (AOTA) explicitly recognizes driving and community mobility as an IADL within occupational therapy’s scope of practice. Their Older Driver Initiative focuses on preserving driving independence for as long as it can be done safely. When driving is no longer an option, the IADL doesn’t disappear. It shifts to community mobility: using public transit, taxis, ride-hailing apps, or specialized transport services. The goal is maintaining the ability to get where you need to go, whether or not you’re behind the wheel.
Why Driving Is an IADL, Not a Basic ADL
Basic ADLs cover fundamental self-care: grooming, toileting, getting dressed, feeding yourself, and moving around your home. These are physical tasks that most people perform almost automatically. IADLs sit a level above. They involve the organizational and cognitive skills needed to live independently in a community, things like managing finances, preparing meals, handling medications, and arranging transportation.
Driving demands an unusually broad set of abilities compared to most IADLs. Research into driving competency in older adults has identified at least 18 distinct components grouped into seven categories: cognitive function, sensory ability, motor skills, mental health, medications, medical conditions, and driving history. On the cognitive side alone, safe driving requires sustained attention, quick reaction time, multitasking, visual processing, working memory, executive function, and visual search. That’s why driving is often one of the first IADLs to show strain when cognitive decline begins.
How Driving Ability Gets Assessed
Because driving sits at the intersection of so many skills, no single test captures it. Clinical assessments typically combine cognitive screening, physical evaluation, and sometimes an on-the-road driving test. Occupational therapists use tools like the OT-DORA (a battery that includes both cognitive and physical components) and the Clinical Assessment of Driving Related Skills. Some screening tools take a broader view: the “4Cs” approach, for example, looks at crash history, family concerns, clinical condition, and cognitive function together.
Cognitive screening scores can flag when a formal driving evaluation is warranted. Clinicians generally consider recommending a driving evaluation when scores on common cognitive tests drop below certain thresholds. People with dementia who have already lost the ability to perform two or more IADLs due to cognitive decline, while still managing basic ADLs, are considered at higher risk of driving impairment.
Warning Signs of Declining Driving Ability
Because driving is such a cognitively demanding IADL, changes in driving behavior often signal broader functional decline. The Alzheimer’s Association identifies several red flags:
- Forgetting how to get to familiar places
- Missing traffic signs or signals
- Driving too fast or too slow for conditions
- Becoming confused or angry behind the wheel
- Poor lane control or hitting curbs
- Making errors at intersections, especially left turns
- Confusing the gas and brake pedals
- Taking longer than expected to return from routine trips
- Forgetting where you were headed while driving
Crash data reflects this pattern. Most motor vehicle crashes involving older drivers happen during daytime, on weekdays, and in complex situations like intersections, left turns, and highway merges. The common thread is failing to yield, missing stop signs or red lights, or drifting out of lane position. These aren’t random errors. They point to the specific cognitive demands (attention, processing speed, decision-making) that make driving one of the most challenging IADLs.
What Happens When Driving Stops
Losing the ability to drive carries serious health consequences, precisely because it’s such a central IADL. A meta-analysis pooling data from five studies found that stopping driving nearly doubles the risk of depressive symptoms in older adults, with an odds ratio of 1.91. That’s a strong and consistent association. Beyond depression, driving cessation is linked to declines in general health, physical function, social engagement, and cognitive ability. Former drivers also face greater risk of admission to long-term care facilities and higher mortality rates.
One study tracking adults 65 and older over five years found a rapid decline in overall health trajectory after they stopped driving. Former drivers consistently reported worse health-related quality of life compared to those still behind the wheel. The connection makes sense: when you can’t drive, it becomes harder to get to medical appointments, maintain social relationships, shop for groceries, and stay physically active. One lost IADL cascades into others.
Community Mobility as an Alternative
When someone can no longer drive, the transportation IADL doesn’t end. It shifts to other forms of community mobility, and this transition matters. AOTA has developed a Checklist of Community Mobility Skills that evaluates roughly 20 person-specific factors (split about evenly between physical and cognitive abilities) against three tiers of transportation: public transit like buses and subways, ride-hailing services and taxis, and specialized assisted transport programs. Each option has different demands. Riding a city bus independently, for instance, requires route planning, the ability to walk to a stop, balance while standing, and the cognitive flexibility to handle schedule changes.
Practitioners rate each skill as green (independent), yellow (needs assistance), or red (unable even with help), then match the person to realistic transportation options. The goal is preserving as much independence and community participation as possible, because that’s what the transportation IADL is really measuring: not whether you can operate a car, but whether you can get yourself where life requires you to go.
