All Denver Department of Motor Vehicle branches will be closed Monday and Tuesday so officials can chip away at a 52-day backlog in registrations and titles.

The “two-day sprint” is expected to reduce the backlog by at least 10 days — or 22% — DMV officials said in a news release last week.

“The mail backlog is leading to increased traffic in the branch locations, increased calls to Denver 311 and the DMV branches as well as increased frustration and wait times for customers,” DMV officials wrote.

The department cited “significant turnover” in recent months, reporting as high as 40% vacant positions as of late August/early September, a DMV spokesperson said.

Twenty-six new employees will begin training next week to start work in November, while current DMV staff will be working overtime hours during the week and on the weekend.

DMV offices will reopen Wednesday, and officials encouraged drivers to complete title and registration online at denvergov.org/dmv or mydmv.colorado.gov.
