The OMV will review your request and documentation and determine if your request can be accommodated. If your request is approved, the OMV will work with you to schedule a testing appointment that meets your needs.
It is important to note that requests for accommodations must be made in advance of your testing appointment. Additionally, the OMV may require additional documentation or information before making a decision on your request.
