Dr. Lee is a NRCME examiner. That might not mean that much to you, unless you or someone you know drives a large truck or commercial vehicle. DOT cards expire at midnight on the date of expiration. There is no grace period. Can’t tell you how many people have called our office from their impounded vehicle on the side of the road, while the trooper is just ticketing away wanting the first available DOT medical exam appointment. Save yourself a few C notes and check that date now, then call us.
