California automobile accident attorneys alert- Twelve people were injured in a three-vehicle crash in San Francisco, CA.

San Francisco, CA—A slow-speed, rear-end collision between a Muni streetcar, bus and a car has left investigators baffled as what could have caused the collision. The Tuesday, April 6, 2010 wreck sent several people to the hospital after the 4:41 p.m. crash, as reported by the San Francisco Chronicle.

The San Francisco police reported a F-Market streetcar hit a 10-Townsend bus that was traveling westbound on Market Street near Second Street. Following the collision, the bus was then thrown into a car. The collision sent five people to the hospital for treatment of their undisclosed injuries. Seven other victims were treated and evaluated at the scene and than released. Both the Muni streetcar and bus drivers were transported to the hospital to be tested for drugs and alcohol as apart of standard procedures. It is unknown if they sustained any injuries. Investigators do not believe at this time through preliminary investigations that either driver was under the influence of any control substances.

According to accident investigators, a “preliminary inspection found that a mechanical failure of the brake system may be at fault.” The operator of the streetcar reportedly told investigators that he applied the brake but they didn’t work. A cause for the crash has yet to be determined.
