If you have been asked by your attorney for a letter from the doctor that you can drive safely, we need you to get this test done in addition to an office visit. This test helps assess the neuro-cognitive function and improve safety for patient as well as other drivers. Please note that this test if it is done outside the office can cost as much as $700. We provide this at this low cost as a service only to our existing patients. We do not bill your insurance.
