Relating to authorizing an optional county fee on vehicle registration in certain counties to be used for transportation projects.

HB 3116 would allow specific Texas counties to add an optional $20 fee on vehicle registrations to fund local transportation projects. It applies to counties bordering Mexico with over 250,000 residents, counties with 1.5 million+ population sharing a regional mobility authority, or counties with 190,000-1.5 million residents in such authorities. Counties with under 700,000 residents could increase the fee to $20 only if approved by a voter referendum. The bill modifies existing transportation code to enable this funding mechanism without creating new taxes. It does not require state approval but mandates local voter consent for the fee increase.
