D.C. residents trying to get around the city may soon have a new rentable option – mopeds.

District Department of Transportation officials will launch a four-month pilot program to allow shared moped companies to apply for permits to operate up to 400 vehicles in the District, agency officials announced Friday. Under the program’s guidelines, riders must wear a helmet, possess a valid driver’s license and may not operate the moped on sidewalks.

“This demonstration period will allow the District to evaluate how mopeds will fit in our transportation network,” DDOT Director Jeff Marootian said in the release. “This is another opportunity for us to reduce dependence on single-occupancy vehicles and expand the sustainable transportation options we offer to residents and visitors.”

DDOT officials will make the terms and conditions for the moped pilot program available on the agency’s website by August 12, the release states. The initiative will grow the fleet of shared vehicles on D.C. streets, which includes cars, dockless and electric bicycles and motorized scooters.

Moped companies Muving and Revel have expressed interest in bringing vehicles to D.C., WAMU reported Friday. In areas where the companies operate, like New York City and San Francisco, Muving charges riders 80 cents per minute to ride one of its mopeds, while Revel charges users $1 to start a moped and 25 cents per minute for the duration of the ride.

“As Washington, D.C. continues to be a national model for embracing innovative and sustainable transportation options under Mayor Bowser’s leadership, we look forward to this permit process for shared mopeds,” Frank Reig, CEO and co-founder of Revel said in a statement to WAMU. “We hope to be fortunate enough to be selected by DDOT so that we can introduce our shared electric mopeds to the whole District soon and provide a reliable and convenient way to help people get where they need to go while also supporting local jobs.”
