D.C. Mun. Regs. tit. 18, r. 18-106
A diabetic furnishing data showing the following may be issued a license without qualification, except as provided in this section:
A diabetic who meets the requirements of § 106.1, who is seventy (70) years of age or over, or who is between sixteen (16) and twenty-five (25) years of age and is applying for his or her first license in any jurisdiction, will be referred to the Department of Motor Vehicles' Driver Services Administrator for review and approval prior to the issuance of a license or permit.
A diabetic who fails to furnish data meeting the requirements of § 106.1 may be issued a license or permit, but the case shall be referred to the Department of Motor Vehicles' Driver Services Administrator for review and approval prior to the issuance of a license or permit.
If the reports indicate satisfactory control of the diabetes and do not show diabetic eye pathology, no further medical or vision reports are required until license renewal.
If either the vision or medical report suggests the probability of rapid progress of the disease, or if the vision is compromised, reports may be requested at shorter intervals.
Forms furnished to diabetic applicants and licensees shall clearly state the conditions described in this section.
An applicant receiving treatment for episodes of altered consciousness or seizures may be issued a driver's license if, in addition to meeting all other requirements of this chapter, the applicant annually furnishes the Director with a licensed medical practitioner's certificate indicating the following:
The annual licensed medical practitioner's certificate shall no longer be required after a five (5) year period of freedom from seizures.
An applicant shall be required to sign an affidavit that he or she has had no seizure or altered consciousness in the year immediately preceding the date of the application. If a seizure or episode of altered consciousness has occurred within a shorter period of time than one (1) year, the applicant may be considered for a license, at the discretion of the department's medical officer, if he or she meets one of the following requirements:
An applicant with a seizure disorder may be required to sign a similar affidavit every twelve (12) months when the licensed medical practitioner's certificate is not required. If the applicant fails to file an affidavit, the applicant's license shall be revoked until the applicant furnishes the Director with evidence that the applicant is physically qualified within the meaning of this section.
Persons who are hard of hearing or who are totally deaf may operate a motor vehicle only if the vehicle is equipped with a properly positioned outside mirror on the left side of the vehicle.
Any permittee who develops a physical condition covered by this section shall, within thirty (30) days of learning of the condition, appear at the Department, in accordance with the following:
Following review of the permittee's medical condition, the Director may either allow the license to remain in place, reissue the license with conditions necessary to ensure the safety of individuals and property, or revoke the license if the person is not physically qualified to operate a motor vehicle in a manner not to jeopardize the safety of individuals or property.
Failure to appear when required by § 106.12 may be grounds for revocation pursuant to § 302.2.
The Director may suspend a driver's permit if more time is required to evaluate a permittee and may, in his or her discretion, issue a temporary license to a permittee if consistent with public safety.
