After AB 60 went into effect at the beginning of the year, over half of the driver's licenses issued in California are for undocumented immigrants.

According to the DMV, around 397,000 of the 759,000 licenses issued in 2015 so far are for people who are in the country illegally. "We hope that all of those people will be able to pass the testing and have the necessary documents to obtain," a DMV spokeswoman told the Associated Press. The department expects around one million more people apply for a drivers license under the law over the next three years.

"It's great that people are taking advantage of this new law," said Jackelin Aguilar of Placer People of Faith Together. "It's definitely a step forward for the families, and having identification is huge."

Proponents say the law ensures the roads are safer for everyone. Opponents say it's government-sanctioned encouragement for people to enter the country illegally. The license is not a valid form of federal identification.

Around 687,000 people have applied for the license, which drew long lines at DMVs throughout the state in January and February. Applicants have to pass a driving test and provide proof of residency and a form of valid identification in order to obtain one.
