Summary
This report updates the Driver Licensing Policies and Practices (DLPP) database, originally compiled in 2009, to document current state-level policies regarding older and medically-at-risk drivers. Motivated by the increasing proportion of older drivers and the need to manage safety and mobility for this vulnerable population, the study aims to provide a comprehensive reference for researchers, policymakers, and stakeholders. The objective was to verify and update licensing practices across all 50 states and the District of Columbia, highlighting commonalities and changes since the previous review. The study employed an online survey administered to personnel from each state’s driver licensing agency between January and April 2019. The survey utilized the 2009 DLPP database as stimulus material, pre-filling response fields with existing data to allow respondents to verify accuracy or specify changes. Topics covered included vision requirements, renewal cycles, reporting mechanisms for at-risk drivers, medical review processes, license restrictions, examiner training, and public outreach. Study staff conducted follow-up clarifications via email or phone to ensure data coherence and completeness. The results reveal significant variation and recent shifts in state policies. Regarding renewal cycles, 21 states (41.2%) have age-based shorter renewal periods, while others adjusted cycles due to Real ID requirements. In-person renewal requirements vary, with 16 states requiring older drivers to renew in person more frequently than younger counterparts. Vision testing is conducted by 37 states during routine renewals, with most requiring 20/40 acuity; however, no states test contrast sensitivity. Reporting mechanisms are widespread: 47 states ask applicants to self-report medical conditions, and all states allow physician reporting, with 37 states offering civil immunity to physicians. Family and friend reporting is permitted in 46 states. Medical review processes rely on Medical Advisory Boards in 35 states, while others use staff physicians or the driver’s own physician. Most jurisdictions refer drivers to their own physicians or vision specialists for evaluation. License restrictions are available in nearly all states, commonly including daylight-only driving and special vehicle equipment. Training for license examiners on older driver issues is specialized in 25 states, with topics ranging from medical conditions to aging sensitivity. Public outreach includes dedicated websites and handbooks in roughly half of the states. The significance of this update lies in its provision of a current, systematic baseline for comparing state approaches to managing older driver safety. By documenting changes such as the expansion of online reporting forms, shifts in in-person renewal frequencies, and variations in medical review structures, the report highlights the evolving landscape of driver licensing policies. This data supports evidence-based policy development and helps identify best practices for balancing the safety of medically-at-risk drivers with their mobility needs.
Key finding
Major policy changes were documented since the 2009 survey, including 21 states adopting age-based renewal cycles, Real ID requirements driving renewal cycle uniformity changes, 17 states expanding medical condition reporting to all renewal types, Michigan changing visual acuity standards from 20/40 to 20/50, and Kansas lowering in-person renewal age threshold from 70 to 50. Only Mississippi has no mechanism for reviewing medically-at-risk drivers, and only Illinois requires road tests for older drivers.
