District Department of Transportation officials are allowing more dockless vehicle companies into the city.

Six dockless vehicle companies currently operate in the city and can expand its fleets every three months. But companies that have not been approved to add its fleets to District streets can now apply through June 14, according to a DDOT release Friday.

“Allowing additional dockless vehicle operators increases options for riders and helps to reduce the reliance on automobiles in the District,” DDOT director Jeff Marootian said in the release.

Approved applicants can operate up to 600 dockless vehicles between July 1 and Dec. 31, the release states. Companies that file for a permit now will be eligible for fleet expansion in October after reapplying for a 2020 permit, according to the DDOT website.

DDOT capped the number of dockless vehicles allowed to operate in D.C. at 6,000 in December, more than doubling the previous 2,400-vehicle cap. With an additional application period, the agency aims to accept at least two more dockless vehicle operators to reach its new 6,000-vehicle cap, the website states.
