Rentable mopeds hit the D.C. streets last weekend, and it wasn’t long before a rider was hospitalized in a crash.

FOX 5’s Evan Lambert reports that a rider hit a pothole between 13th and P streets NW in Logan Circle on Sunday, and fell off the moped. Part of the vehicle landed on the rider, who was hospitalized and diagnosed with a broken collarbone, per FOX 5, which obtained photos of the crash and of the rider’s broken collarbone.

It’s been nearly two years since D.C. initially launched its dockless vehicle pilot program, which began with bikes and has grown to include scooters and now, mopeds.

The District Department of Transportation launched a four-month test phase for rentable mopeds this month. The first company to score a permit for the program is Revel, which can operate up to 400 vehicles in the city. There are a slew of rules associated with the moped pilot, including that riders must be 21 with a current driver’s license and a helmet; speeds are capped at 30 mph; mopeds are limited to local streets and must be parked on the street; and more. Additionally, D.C. riders are covered up to $300,000 in third-party liability insurance.

“We are aware of the unfortunate incident in Washington, D.C. involving a rider,” a Revel spokesperson told DCist in a statement. “Safety is our number one priority. This is why we verify riders have a safe driving history as part of our registration process, why we require all riders to use the helmets we provide on each Revel, and why we offer free lessons.”
