Assembly Bill 60, authored by then-Assemblyman Luis Alejo in 2013, required California DMV offices to issue driver’s licenses to undocumented immigrants as long as they can prove their identity and residence within the state. The law has led to 1,001,000 undocumented immigrants receiving licenses as of March 31 but doesn’t give the licensees carte blanche to drive outside of California or fly across state or federal borders.

“Immigrants are getting tested, licensed and insured and this is making our roads safer for everyone,” said Alejo, now a Monterey County supervisor, in a prepared statement. “Today, we see the law working the way it was intended to and has dramatically improved the lives of a million immigrants and their families.”
