It happened at around 3:00 p.m. along Divisadero St. just south of Vallejo St.

Police said the truck, which was being used to collect garbage at a construction site, had no driver in it when it rolled down a steep hill and hit multiple parked cars before being stopped by a tree at Divisadero and Vallejo.

Alex Galvan, owner of Smart Demolition and Excavation, told KPIX 5 that his employees parked the truck with the emergency brake on, delivered the truck to the construction site and then left. He says the truck was also on special parking wedges to keep it from sliding.

But Galvan said construction workers told him as they were loading the truck with garbage, the truck began to move, rolled over the wedges, and then careened down the hill.

The three people who were hurt, an Uber driver and his passengers, suffered non-life threatening injuries.
