Southern California residents who planned to brave the lines at the Department of Motor Vehicles today had an additional hurdle — the computer systems at more than 100 offices statewide were down.

The “internal issue” started Monday at DMV headquarters in Sacramento and was described as a “catastrophic hardware failure” by spokeswoman Jessica Gonzalez.

Crews have to rebuild the computer system to get 105 field offices across the state up and running again.

“Vehicle registration and driver license and ID card transactions could not be completed at the affected offices,” Gonzalez said, adding DMV customers could still renew their vehicle registrations at self-service terminals inside the branches.

The outages are expected to be resolved by Wednesday morning, Gonzalez said.

Despite the digital disruption, Californians could still take their driving tests, make return appointments, get help with paperwork and have their questions answered, according to a statement released by the DMV Tuesday.

“The department wants to remind customers that DMV online services are still available at www.dmv.ca.gov and apologizes for any inconvenience this issue has caused,” the statement reads.
