To addresses these concerns, some states have e enacted data retention limits.

Other states, like Texas, have laws that restrict law exement' s ability to share ALPR data with out- of- state agencies cout a formal data- sharing agreement. Howeveer, exement of these rules is oftein weak, and many agencies lack consight oversight.
