Typically, if an individual is physically capable of driving a motor vehicle, they are capable of operating an Ignition Interlock Device (IID).  The Board of Tests has accommodated the reduction of the required minimum breath volume from 1.5 to 1.2 liters for any participant that makes the request. This is the lowest level of breath volume at which IIDs have been tested by the National Highway Traffic Safety Administration.  

A Participant rarely struggles with producing the required volume, but instead struggle with the anti-circumvention feature of a specific IID.  Therefore, it is recommended that a participant test a demonstration unit of the IID they are interested in installing.  This will help a participant decide whether they will be able to operate the IID on an ongoing basis.  There are many distinct models of IID approved in Oklahoma, which gives a participant a good chance of finding an IID they are comfortable with operating.  Historically, the Board has had numerous IID participants with diminished lung capacity, amputations, traumatic brain injuries, and other limitations, complete IID requirements in the State of Oklahoma.  An exemption may be requested by persons who meet the following requirements.  

Medical Exemptions

Only BOT IDAP participants whose driving privileges are suspended 180 days pursuant to 47 O.S. §6-205.1(A)(1) are eligible for a medical exemption and such exemption will not grant the individual driving privileges. 

Individuals seeking medical exemption must:

(A) obtain a pulmonologist’s certification indicating the person has a                      documented medical condition preventing the person from providing a breath sample of at least one and two-tenths (1.2) Liters; and

(B) apply for the IDAP program and at time of application, upload the Notice of Revocation and the letter from the doctor; and  

(C) provide the exemption letter from the Board of Tests to Service Oklahoma.

Participants denied medical exemption may appeal the denial.
