PREFACEThe Texas Medical Advisory Board (MAB) for Driver Licensing was established in 1970 to advisethe Texas Department of Public Safety (DPS) in the licensing of drivers having medical limitations,which might adversely affect driving. See Chapter 12 of the Texas Health and Safety Code, Sections12.092–12.098.Realizing a need for criteria with which to judge the cases consistently and fairly, the MAB membersassembled a set of guidelines. The original set of guidelines was composed of some informationborrowed from the American Medical Association's Physician's Guide for Determining DriverLimitation with input from MAB members. However, further revisions in 2013 were made, utilizingthe expertise of MAB members and other physicians along with a guide, entitled: “Driver FitnessMedical Guidelines” produced in 2009 by the National Highway Traffic Safety Association (NHTSA)and The American Association of Motor Vehicle Administrators (AAMVA) to assist licensingagencies in making decisions about an individual’s fitness for driving. MAB’s current revisedguidelines are entitled: “Guide for Determining Driver Limitations for the Medical Advisory Board”.The ultimate goal is to allow all who can drive safely to do so, and to continue to reduce the numberand severity of motor vehicle accidents in Texas. The Texas Transportation Code, Chapter 521charges DPS with the responsibility of determining if applicants or licensees should or should not belicensed when a medical condition exists that could possibly affect their ability to drive. There areseveral types of examinations that can legally be required as part of the medical review and licensingprocess to help make the determination - one of which is a complete medical examination.The Medical Advisory Board operates solely in an advisory capacity and DPS relies heavily on theirprofessional advice, and has the final responsibility for licensure.No individual is permitted to appear personally before the Medical Advisory Board. The MABreviews medical facts provided by the licensee’s attending physician and sometimes other relevantevidence. MAB member physicians utilize their expertise and accumulated years of experience alongwith its MAB guidelines in reaching an opinion. MAB meets every other week to review cases. Aftercompletion of its reviews, the MAB makes a written recommendation for each case reviewed which isforwarded to the DPS Driver License Division. After receiving MAB’s opinion, DPS notifies theindividual by mail of its decision concerning licensure. This takes approximately two (2) weeks fromthe time it receives the MAB recommendation.As the driver licensing agency for Texas, DPS is solely responsible for all actions taken or initiated.Neither the Medical Advisory Board nor the attending physicians are legally liable for the decisions oractions taken by DPS in the suspension, revocation or denial of driver licenses. The DPS decisionmay be appealed to the courts for final determination.Reviewed 08/31/2020Revised 03/2014

FUNCTIONAL ABILITY PROFILESFunctional ability to operate a vehicle safely may be affected by a wide range of physical,mental or emotional impairments. To simplify reporting and to make possible acomparison of relative risks and limitations, the Medical Advisory Board has developedFunctional Ability Profiles for ten categories and seven subcategories, with multiplelevels under each profile. These categories and subcategories are listed in Tables 1-15.Each profile follows the same format:1. No diagnosed condition. This section is used for a patient who has indicatedto the Department of Public Safety a problem for which no evidence is found,or for which no ongoing condition can be identified. For example, thiscategory might apply to a person with a heart murmur as a young child whoindicates heart trouble, or to a teenager who fainted in gym class once on a hotday who indicates blackouts.2. Condition. Fully recovered/compensated. This category indicates a history ofa condition which has been resolved or which does not warrant review.Guidance for the use of this section is given in each profile3. Active impairmenta. Minimal. This section may call for a periodic review because of anongoing condition which could deteriorate.b. Mild. This section deals with conditions which may impair driving butwhich are controlled so that a person can still operate a motor vehiclesafely. Reviews are more frequent than in (a).c. Moderate. This section identifies impairment which often precludesdriving, but for which there is the potential for recovery to the point ofallowing safe operation of a motor vehicle.d. Severe. This section identifies permanen
