do all 50 states require a clearance letter and/or interact for drivers licensing purposes?

Answer 1

Licensing is required by all fifty states, and all states, subject to their specific state laws will interact with other states by accepting that particular states license, by a process known as "reciprocity". However, if one state requires you to be 17 and you were licensed at 16 in another state and you are still 16, you cannot get a license in that state until you are 17. However, you can drive in that state under your other states license, until you meet their residency requirement. For example, if the residency takes place after three months in the new state and you are living there and are not yet 17, then your old license, that is good at 16, in the previous state, is no longer valid in the new state. You would be subject to their jurisdiction and could be ticketed for driving on an invalid license. The license would still be good if driving through and around in any other state that you were not a legal resident. Some states allow a period of six months before you are considered a legal resident of that state. Check out the laws of the state you will be moving to, to make sure you are in compliance.

Answer 2

I'm not sure what you mean by "clearance letter" but I believe you're asking if the 50 states interact with each other when concerning drivers license issues.

The answer is yes!

Although each state has its' on requirements for licensing, there is also a "reciprosity" maintained by the states that should a person from one state attempt to obtain an out-of-state license because of outstanding warrants or suspension/revocation actions, the reciprocating states will honor the original states guidelines!

Hope this helps....best wishes!
