Cognitive Changes and Driving Safety: Recognising the Signs and Taking Action
For many Queenslanders, maybe like you, the act of driving extends far beyond mere transportation. It embodies freedom, the ability to maintain connections with loved ones and cherished places, and a vital sense of independence.
However, the seemingly straightforward task of driving is, in reality, a complex interplay of cognitive abilities, swift decision-making, sustained attention, and coordinated movement.
When subtle cognitive impairment begins to emerge, it can gradually erode this delicate balance, often without the older driver fully realising the shifting landscape.
Recognising when these cognitive impairment starts to impact driving performance isn’t always easy, often presenting in subtle ways. Yet, taking proactive steps and seeking assessment early can make a profound difference โ safeguarding your well-being, preserving your independence for longer, and ensuring road safety for everyone sharing the roads of our vibrant state.
If you or someone you care about in Brisbane or the surrounding Queensland regions has noticed changes in thinking patterns, memory recall, or the ability to make decisions, this comprehensive guide is designed to shed light on what these changes could signify for driving safety โ and, crucially, what supportive steps can be taken.
Understanding of how cognitive abilitiesinfluence driving is the first step and one we check in our OT driving assessment services.

Why Cognitive Health and Driving Safety Go Hand-in-Hand
Consider the multifaceted cognitive domain demands of a seemingly simple drive to your favourite local cafรฉ in Brisbane.=
Remembering the route: Navigating familiar streets and recalling directions.
Noticing traffic signals and responding promptly: Interpreting and reacting to visual cues.
Judging distances accurately while parking: Perceiving spatial relationships and maneuvering safely.
Making quick and sound decisions at intersections: Processing information and executing appropriate actions in dynamic situations.
Each of these everyday driving tasks relies heavily on critical specific cognitive functions, including memory, sustained attention, processing speed, and executive functioning โ the higher-level skills that allow us to plan, organise, and manage tasks.
While some changes are natural with age, more significant cognitive decline, potentially linked to underlying neurological conditions, can subtly compromise crucial decision-making processes and reaction times โ often without the older driver being fully aware of these evolving challenges.
Extensive research consistently demonstrates a clear association between cognitiveimpairment and an increased driving risk and a decline in overall driving performance.
Recognising this intricate connection early offers people the best chance to implement proactive safety measures and access the support needed to navigate these changes effectively, potentially delaying the need to stop driving.
The Subtle Signs Cognitive Changes Could Be Affecting Your Driving Confidence
It’s important to understand that cognitive impairment impacting driving often doesn’t manifest as sudden or dramatic events like forgetting how to operate a vehicle entirely. Instead, the initial signs can be subtle and easily dismissed.
Paying close attention to these early indicators, both in yourself and your loved ones, is a crucial act of proactive awareness for everyone’s safety on Queensland roads.
Here are some subtle yet significant signs that warrant closer attention and consideration:
Getting lost on familiar routes: Have you, or someone you know, started to experience moments of uncertainty while driving to well-known locations, like the weekly trip to the Indooroopilly Shopping Centre or the regular drive to visit family in Redcliffe? Trouble accurately recalling familiar routes or feeling disoriented in previously navigated Brisbane suburbs can be an early sign that your memory and spatial awareness are being affected. This isn’t about forgetting how to drive entirely, but rather a subtle erosion of your mental map. This driving behaviour may indicate an impact of cognitive impairment.
Difficulty following traffic signals or road signs: Do you sometimes find yourself hesitating at traffic lights in areas like Fortitude Valley, unsure if the signal has changed, or perhaps missing important “no right turn” or “speed limit” signs on roads you’ve travelled countless times? This could reflect a reduced ability to maintain sustained attention, quickly process visual information, and accurately interpret traffic cues โ all essential for road safety and responsible driving behaviour.
Hesitation at intersections: Moments of increased uncertainty or delayed decision-making when navigating intersections, such as feeling overwhelmed when turning onto a busy street in West End or merging onto the Centenary Highway, can often highlight a slowing in cognitive processing speed or emerging difficulties with executive function โ the ability to plan, initiate, and execute actions efficiently in a dynamic environment. This can negatively influence driving.
Increased scrapes or near misses: While minor bumps and scrapes might occasionally happen to any driver, an uncharacteristic increase in these incidents โ such as frequently bumping kerbs while parking in local streets, misjudging distances in tight parking spots, or experiencing more near-collisions than usual โ can be a subtle yet significant indicator of declining spatial awareness, reduced reaction time, and a diminished ability to accurately judge distances and the movement of other vehicles, potentially leading to unsafe driving.
Struggling to multi-task while driving: Have you noticed an increasing difficulty in managing multiple aspects of driving simultaneously, such as holding a simple conversation with a passenger while navigating moderate traffic, or feeling overwhelmed by the sensory input of a busy road environment? This can point to a reduced attentional capacity, making it harder to effectively divide focus between the various cognitive demands inherent in the task of driving. These changes in driving warrant attention.
These seemingly minor shifts may not necessitate an immediate cessation of driving, but they unequivocally warrant careful attention, open communication, and, importantly, a professional cognitive assessment and occupational therapy driving assessment.
Real-World Examples: How Cognitive Decline Shows Up Behind the Wheel
Consider Margaret, a vibrant resident of Kenmore who has always cherished her daily drives to her local nursery, a cornerstone of her routine and social connection. Lately, her family has noticed she’s been missing familiar turns, taking longer and sometimes circuitous routes, and occasionally arriving home feeling flustered and unsure of her journey. This change in her usual driving behaviour suggests potential cognitive decline and highlights the impact of cognitive impairmenton driving.
Then there’s John, a confident retiree from Clayfield who once navigated the intricacies of Brisbane’s inner-city traffic with ease. Now, he expresses increasing anxiety before driving, feels overwhelmed by moderate traffic, and his wife has observed him reacting more slowly to changing traffic conditions. Even people with mild cognitive impairment can manifest such decrements in driving performance, impacting their driving abilities.
It’s crucial to remember that cognitive impairment doesn’t present identically in everyone. For some, it might manifest as occasionally forgetting the intended destination mid-journey. For others, it could involve making poorer judgements regarding speed, lane changes, or parking maneuvers. These shifts in driving behaviour can be a predictor of driving difficulties and are associated with driving.
When patterns of these subtle changes begin to emerge, they can serve as meaningful indicators of evolving cognitive abilities โ and underscore the importance of seeking professional evaluation to ensure continued road safety and well-being for the older adult.
When to Act: Why Early Assessment Matters
Addressing these subtle signs and seeking professional assessment early offers several crucial benefits for individuals and their families:
Reduce the driving risk before incidents occur: Proactive Occupational Therapy (OT) assessing driving through driving skills evaluations can identify risks and areas of concern before they escalate into serious traffic incidents, safeguarding the well-being of the driver and the broader community on Queensland roads.
Gain clarity on the nature and extent of cognitive impairment: A comprehensive assessment provides valuable insights into the specific types and severity of any cognitive decline that may be impacting driving abilities, allowing for a more tailored and supportive approach.
Enable proactive and individualised interventions: Occupational therapy interventions, informed by an early assessment, may help individuals with specific cognitive strengths maintain driving abilities for a longer period or facilitate a smoother and more supported transition when alternative transportation becomes necessary, potentially delaying the decision to stop driving.
Empower informed decisions about driving for drivers and their families: Early insights from a professional assessment empower both the individual and their loved ones to make well-informed and collaborative decisions about driving, reducing the stress and uncertainty often associated with these sensitive conversations.
How Occupational Therapists Assess Driving Fitness
Occupational therapists bring a unique and holistic perspective to the assessment of driving fitness, particularly when cognitive impairment is a concern. As healthcare professionals, we consider far more than just adherence to road rules or the physical ability to control a vehicle โ our evaluation focuses on the whole person and the complex interplay of physical, visual, and, crucially, cognitive performance required for safety on the road.
Our Tiered Approach to Cognitive Fitness for Driving
Stage 1: Comprehensive In-Clinic Cognitive and Simulated Driving Assessment
This initial stage provides a detailed understanding of an individual’s cognitive abilities relevant to driving and their simulated driving skills.
Detailed Neurocognitive Evaluation: A thorough cognitive assessment is conducted, examining critical cognitive domains such as:
Visuospatial Skills (spatial awareness, depth perception) These cognitive predictors are crucial in understanding potential impact of cognitive impairmenton driving.
Observation in a Driving Simulator: We utilise simulated driving scenarios to observe “driving skills” and driving behaviour in a safe, controlled environment. This allows us to assess:
Pedal reaction control (braking)
Reaction to unexpected events and hazards
Decision-making in various driving situations – scanning, awareness and recall
Ability to follow simulated road rules and traffic signals
This stage helps us efficiently triage individuals, identifying those likely to demonstrate safe driving and those who may be at higher driving risk due to potential cognitive decline or mild cognitive impairment.
This practical evaluation is reserved for individuals where the in-clinic assessment presents a clinical grey area or where further real-world observation is necessary to complement the initial findings.
Real-World On Road – Driving Review Conducted in a dual-controlled vehicle with a highly trained driving assessor in diverse Brisbane traffic conditions.
Focus on Applied Skills: The assessor observes the practical application of cognitive function, visual, and physical abilities, specifically looking at:
Hazard perception and response
Decision-making in complex traffic situations
Adherence to traffic rules and regulations
Navigation and route-following abilities
Overall driving behaviour and ability to anticipate and react safely. This on-road driving evaluation provides crucial insight into how any cognitive deficits may affect driving performance in real-world scenarios, particularly for older adults or individuals with cognitive impairments, helping to inform decisions about driving and the potential need to stop driving.
Unlike a standard driving test, our tiered driving evaluation approach offers a more nuanced and cost-effective approach. By combining comprehensive in-clinic cognitive assessment and simulated driving with targeted on-road driving reviews, we aim to provide a thorough understanding of an individual’s fitness to drive while minimising unnecessary costs and stress. Our goal is to promote driving safety and maintain independence for as long and as safely as possible.
For clients who have undergone a recent cognitive fitness-to-drive assessment with us, we also offer our Senior Driver Rehabilitation program to support safe and confident driving.

Supporting Loved Ones Through This Transition
Raising concerns about driving with an older adult experiencing cognitive impairment can be emotional. We suggest:
Choose the right time: Calm and private discussions work best.
Share specific observations: โIโve noticed you missed the turn to the doctorโs recently…โ focusing on specific instances of altered driving behaviour.
Emphasise care, not criticism: Focus on safety on the road and wellbeing related to potential unsafe driving.
Suggest professional guidance: Frame an initial OT driving consultation as objective and helpful in understanding any impact of cognitive impairment.
Itโs not easy, but it can lead to better understanding and support, potentially guiding the conversation towards when it might be time for driving cessation. Drivers with cognitive changes need this support.
Exploring Alternatives: What if Driving Isnโt Safe Anymore?
Sometimes, an assessment highlights that itโs time for the older driver to stop driving. This doesnโt mean losing independence for the older adult.
In Brisbane and across Queensland, options include:
Community transport services
Ride-sharing apps like Uber or Ola
Public transport through Translink
Support from family and friends
With early planning and support, many maintain strong social connections and daily routines without driving, even after driving cessation. This decision to stop driving is significant. Taking the First Step: Speak to Our Team About Your Concerns
