House Bill No. 1419 amends existing laws regarding the operation of street-legal utility vehicles and other motor-driven vehicles in Oklahoma. The bill modifies the definition of a "street-legal utility vehicle" to require a combustion engine with a displacement of at least 400 cc and capable of maintaining speeds of fifty miles per hour or greater, replacing the previous requirement of forty-five miles per hour. Additionally, it specifies that operators of these vehicles do not need an "M" endorsement on their Class D license, provided they are at least sixteen years old and hold a valid Oklahoma driver license.

The bill also updates regulations concerning the operation of self-propelled vehicles, such as minibikes, and allows for the operation of street-legal utility vehicles on U.S. highways in counties with populations under 75,000, as well as on stretches of U.S. highways with speed limits of fifty miles per hour or less in more populated counties. However, it prohibits the operation of these vehicles on the National System of Interstate and Defense Highways. The act is set to take effect on November 1, 2025.
