Relating to authorizing an increase in an optional county fee on vehicle registration in certain counties.

HB 3345 allows certain Texas counties with populations under 700,000 to increase an optional fee on vehicle registrations up to $20, but only if approved by a majority of voters in a special referendum election. This bill directly affects counties meeting the population threshold, giving them a new option to raise local revenue for transportation funding. The key mechanism requires commissioners courts to hold a voter-approved referendum before implementing the fee increase. The law would take effect on September 1, 2025, if passed.
