Vehicle-Miles-Traveled Tax and Associated Mandated Devices - Prohibition (Transportation Freedom Act of 2025)

SB 557 prohibits Maryland state and local governments from imposing a vehicle-miles-traveled (VMT) tax, mileage-based user fee, GPS toll, or similar tax. It also bans requiring the installation of tracking devices in privately owned vehicles to report mileage. The bill amends Maryland law to explicitly block these measures under the "Transportation Freedom Act of 2025," with one exception allowing existing fuel tax agreements under Section 9-205. This directly affects state/local authorities and vehicle owners by preventing new mileage-based taxation or tracking requirements.
