A 9-year-old boy riding an electric scooter without a helmet died Thursday after colliding with a minivan in Herndon's Highland Mews neighborhood, Fairfax County police confirmed.

The crash happened at about 5:30 p.m. in the 3000 block of Madden Court. According to FCPD, the child's scooter struck the rear passenger side of a 2012 Honda Odyssey as the adult female driver turned left from Highland Mews Court into a parking area. The boy was transported to a hospital, where he was pronounced dead.

At a Friday press conference, FCPD Capt. Harold Morris, the department's assistant traffic division commander, said the driver was not at fault.

"There's no indication at this time that there's any unsafe or reckless manner in which the driver, an adult female, was operating this van," Morris said.

Alcohol and speed do not appear to be factors, police said. No charges have been filed. The driver remained at the scene.

Morris confirmed the child was not wearing a helmet at the time of the collision. As of Friday, police had not yet determined what class of electric scooter the boy was riding. Detectives are canvassing the Highland Mews neighborhood for surveillance video and witnesses.

The crash comes roughly a month after the Fairfax County Board of Supervisors voted June 23 to require anyone under 15 to wear a protective helmet while riding an electrically powered scooter, e-bike, or motorized skateboard on local roads. At that meeting, Hunter Mill District Supervisor Walter Alcorn warned that youth e-bike use was surging: "It's only a matter of time before we see serious injuries and worse."

At a separate press conference the evening of the crash, FCPD Capt. Chris Cosgriff, the department's public affairs bureau commander, urged parents to act. He said families should have their children wear helmets, teach them basic safety rules and speak up when they see dangerous behavior in their neighborhoods.

FCPD's victim services division, health and wellness division and chaplains responded to the scene and hospital to support both the child's family and the driver's family, Morris said.

The department also distributed educational materials reminding parents that legal e-bikes must have operable pedals, a seat and an electric motor producing no more than 750 watts. E-dirt bikes and mini-bikes without pedals can require registration, insurance, and a driver's license and are not necessarily legal on public roads.

The FCPD Crash Reconstruction Unit's investigation is ongoing. Anyone with information about the crash can contact the unit at 703-280-0543.
