Expect Honolulu’s driver’s licensing and state identification card processing functions to remain out of service until Friday, but motor vehicle registration operations to be back to normal starting today, city officials said Wednesday.

Processing of the same services in the state’s three other counties is also either suspended or slowed until the city fixes the computer problems it’s been experiencing since Monday. The city, under a contract with the state, maintains the statewide database accessed by all the counties for driver’s licenses, vehicle registrations, state IDs and other services.

Honolulu Mayor Kirk Caldwell said Wednesday afternoon that “the goal is to try to get everything back to where it should by the end of this week. Hopefully it will be before that, but just to be certain, by the end of this week and we’ll come back to you if we can’t do that.”

Keith Ho, deputy director for Honolulu’s Department of Information Technology, said the agency believes the system’s problems are tied to the existing security software trying to mesh with a new, $1 million mainframe system.

Experts from vendors IBM and Computer Associates are helping with the fixes, Caldwell said.

City Customer Services Director Sheri Kajiwara said Oahu’s five driver’s licensing centers are partially closed. “The (customer service) windows are shut but we are still doing driver’s license road tests,” she said. “So if you have appointments, please keep them. If you’re trying for a walk-in, they’re still available.”

As of Wednesday afternoon, driver’s license renewal operations were expected to stay down at least through today, Kajiwara said. State ID card processing, which uses the same system, also will be down until the problems are fixed.

Motor vehicle registration processing will operate at regular business hours at all nine satellite city halls starting today.

To help vehicle owners with registrations expiring June 30, the city is allowing a one-time extension through July 7. To take advantage of the extension, registrants should make a payment directly at a satellite city hall, or by mail with a postmark no later than July 7, Kajiwara said. There will be no extension or penalty waiver for online vehicle registration payments.

As far as driver’s license renewals, Customer Services is waiving late fees for a 90-day grace period from the expiration date during this time.

Honolulu Police Department Acting Deputy Chief Clayton Kau said officers will honor the extension for vehicle registrations that expire June 30, but may cite people with expired driver’s licenses because the law does not allow any grace period for operating without a valid license.

Caldwell said he is sending a letter to the Judiciary explaining the situation.

Officials from Hawaii, Maui and Kauai counties also said vehicle owners facing June 30 deadlines to renew registration will be given a one-week extension through July 7 to get into compliance. The Kapalama Hale driver’s licensing branch will open Saturday to help with the driver’s licensing backlog — assuming its operations are back up by then, Kajiwara said.

“The system is working, but it’s just working really slow,” Caldwell said. “So what happens is it starts to process the information of the user when you come online, and then it times out, shuts down, before you can get all the way through. That’s the problem we’re trying to solve at this point.”

Kajiwara said the city never actually stopped processing vehicle registrations, “just very slow and spotty at times. Some computers could log on, others could not. Some transactions were lost midway. Some clerks got kicked off when others logged on. It was vastly improved by Tuesday.”

Customer Services issued a press release Wednesday that encourages customers to use online services or the mail when possible. For more information, go to honolulu.gov/csd. Questions about city driver’s licensing centers can be directed to 768-9100 between 8 a.m. and 4 p.m.
