Four people were sent to the hospital after a Muni accident on December 30, 2011. The San Francisco Municipal Railway light-rail vehicle hit the side of a police car just before 5:45 a.m. at the Third Street and 22nd Street intersection. Muni crews were on site afterward, while the police investigated the cause of the crash.
The Muni vehicle was traveling north on Third Street, on the T-Third line and traveling at a low speed when it hit the police car. Two police officers, a Muni operator and a female passenger suffered minor injuries. The two police officers were taken to San Francisco General Hospital for treatment. The Muni operator and the female passenger were taken to California Pacific Medical Center's St. Luke's Campus.
None of the people in this accident had life-threatening injuries. But sometimes seemingly minor injuries can lead to serious injuries as early as a few hours to as much as days later, a person injured in an accident should always get checked out after an accident.
The Muni vehicle and a traffic signal were also damaged in the Muni accident. After the accident, shuttle busses took the Muni passengers on the T-Third line. This continued for about two hours because the intersection was shut down. The Muni vehicle went to the maintenance yard for repairs. Once it was cleared from the intersection, at about 7:45 a.m., regular service resumed. Crews were still on site at the intersection until about 8:20 a.m. to repair the damaged traffic signal.
