Summary

This document, published by the National Highway Traffic Safety Administration (NHTSA) in July 2023, serves as a fact sheet for medical professionals regarding the impact of cognitive conditions on driving safety. It addresses the critical need for clinicians to identify and manage driving risks associated with cognitive impairments, providing a structured overview of how specific cognitive deficits manifest in driving behaviors. The paper aims to guide healthcare providers in assessing patient fitness to drive and intervening when necessary to prevent accidents. The content is organized into two primary sections: a detailed mapping of cognitive impairments to their specific effects on driving, and guidelines for the clinician’s role in assessment and management. The first section categorizes impairments into attention, judgment and problem-solving, planning and sequencing, reaction time, impulsivity, visuospatial abilities, memory, and loss of consciousness or control. For each category, the document lists specific functional deficits. For instance, attention deficits are linked to decreased awareness, reduced processing speed, and difficulty switching attention between objects, which results in delayed responses to traffic hazards, pedestrians, and control devices. Judgment and problem-solving deficits are associated with poor decision-making and an inability to anticipate events, leading to improper signaling and delayed reactions to changing traffic conditions. Planning and sequencing issues cause drivers to become lost, panic, and make irrational directional changes. Impulsivity is linked to road rage, aggressive driving, and failure to check intersections. Visuospatial and memory deficits result in difficulty maintaining lane position, merging, parking, and following directions, often requiring passenger instruction. The second section outlines actionable steps for clinicians. It advises conducting or referring patients for functional driving evaluations if there is evidence of cognitive impairment. Specific indicators warranting evaluation include a history of recent crashes or moving violations, use of psychoactive medications (such as benzodiazepines, neuroleptics, or antidepressants), a history of falls, or positive results from simple cognitive screening tools. For patients diagnosed with dementia, the document recommends addressing driving safety with patients and families, developing a comprehensive transportation plan that includes alternative options and driving restrictions, and coordinating with caregivers. Clinicians are also instructed to perform focused medical assessments, including serial evaluations, to monitor new impaired driving behaviors and assess cognitive abilities such as memory, attention, judgment, and visuospatial skills. The significance of this fact sheet lies in its provision of a standardized, evidence-based framework for medical professionals to identify driving risks in patients with cognitive conditions. By linking specific cognitive deficits to observable driving behaviors and providing clear clinical guidelines, it supports safer decision-making regarding patient mobility and public safety. The document draws upon established guidelines from the AAMVA Driver Fitness Working Group and the American Geriatrics Society, reinforcing its credibility and utility in clinical practice.

Key finding

Cognitive impairments in areas such as attention, judgment, and memory significantly compromise driving safety by causing delays in hazard response, poor lane control, and difficulty with route planning.
