“What we’re trying to do is warn people,” said Walsh, who also called for railroad-style safety controls. Sen. Richard Alarcon, D-Van Nuys, who had called for the line to be shut down after previous crashes, said he is not pursuing closure but wants a safety audit to “ensure it is as safe as possible.” County Supervisor Zev Yaroslavsky, an MTA board member, and Councilwoman Wendy Greuel dismissed calls to shut the line down, saying new signs and other measures are being taken to ensure that the line is safe.

An Orange Line bus and a pickup truck collided early Thursday morning, sending three bus riders to the hospital in what officials called a minor crash – but critics cited as another example of the busway’s safety problems. Police said one of the drivers ran a red light, and they are investigating. The MTA’s bus driver said the pickup truck driver ran the signal on southbound Kester Avenue at the busway. The crash was the fourth since the line opened last month. All the other incidents involved motorists running red lights or failing to stop at the new signals around the busway. “All of these accidents have been minor. All of them appear to be the result of drivers running red lights,” said Metropolitan Transportation Authority spokesman Dave Sotero.

Orange Line riders on other buses later Thursday said they were not concerned. “Most of the accidents are because people don’t understand the rules of the road,” said Karen Martinez, who was taking the Orange Line to Pierce College. “I don’t think the bus is what you have to worry about. It’s other drivers.” But longtime MTA watchdog John Walsh and his United Riders of Los Angeles called for a 72-hour shutdown of the bus line to conduct a safety audit.
