OC Go, also known as Measure M, is a 30-year half-cent sales tax for transportation improvements in Orange County through 2041. After experiencing the success and progress of the original Measure M, nearly 70% of voters renewed the half-cent sales tax in 2006 to launch OC Go.

Why do we have OC Go?

In 2006, Orange County voters gave OCTA a vote of confidence and approved a 30-year extension of an existing half-cent sales tax that was set to expire in 2011.

This renewal allows OCTA to continue making transportation improvements, one half-cent at a time, that benefit the public and the local economy. As of fall 2020, OC Go is expected to generate approximately $11.6 billion through 2041.
