It fails otherwise it would still be valid. The question is how you Handel failure.  An expired certificate is clearly a lower risk than a revoked sertificate, so only haing one failure mode regardless of cause is unnessisary.<p>PS: With an expired license the number of days past expiration is important in most states.  Wait long enough and you need to retake the driving test, so clearly before that point it&#x27;s still somewhat valid.
