Legally a Tennessee judge does not have the authority to physically take possession of your out-of-state driver’s license. Your driving privileges will be revoked in the state of Tennessee, and it will likely be revoked within a reasonable amount of time in your home state. It could take a few weeks or a few months until you are notified by your home state that your driving privileges are revoked due to an implied consent violation in Tennessee. Until you are notified by your home state your license will not be affected by a Tennessee violation, but it inevitably will be affected as soon as your home state receives notification from Tennessee.
Unfortunately, there are times where Tennessee judge take possession of an out-of-state license and generally there is nothing your lawyer can do to prevent the judge from taking it other than notifying the judge that it is an out-of-state license to which the judge does not have authority over. However, if a Tennessee judge takes your license, you should be able to go to your DMV in your home state to get a new valid license for the time being until your home state learns of your violation.
