An annual campaign on local roadways by Montgomery County firefighters to raise money for the Muscular Dystrophy Association led to a minor injury on Friday morning.

A firefighter from Station 33 had his toe run over by a vehicle after the motorist donated to the “Fill the Boot” campaign at the intersection of Montrose and Seven Locks roads in Rockville, Montgomery County Fire and Rescue Services spokesman Pete Piringer said. The incident occurred around 10 a.m. and firefighters are no longer collecting donations in the area, Piringer said.

The “Fill the Boot” campaign is an organized donation drive by the International Association of Fire Fighters union across the country around this time each year. The campaign raised $24 million in 2017.

Piringer said the firefighters participating in the campaign wear fluorescent safety vests and have other safety guidelines in place as they solicit donations at intersections in the county. The firefighter injured on Friday morning was treated and released with no serious injury. The firefighter’s name was not released.

Piringer asked motorists to remain vigilant as the campaign continues.
