An unoccupied Hyundai coupe broke free from a flatbed tow truck heading westbound on Interstate 580 in Castro Valley in December 2025, crossed an approximately 20-foot gap between the elevated highway and BART tracks, and caused a crash with two other vehicles resulting in major injuries, according to CBS San Francisco. The incident disrupted BART service and closed lanes of I-580.
Operator takeaway
A vehicle that falls off your flatbed at highway speed becomes a projectile — check every strap, chain, and securement point before merging onto the highway, every time.
