A motorist received minor injuries Monday in a collision with a Sound Transit light-rail train in Rainier Valley, the third incident since frequent train testing began there this spring.

The crash happened just after 5 p.m. at Martin Luther King Jr. Way South and South Myrtle Street, next to the Othello light-rail station in Southeast Seattle.

Sound Transit spokesman Bruce Gray said the car was heading south and made a left turn, against a red light, from MLK Way onto Myrtle as the train traveled south alongside in the median of MLK.

The driver, a man in his 70s, was taken away by ambulance with minor injuries, said Seattle Fire Department spokeswoman Helen Fitzpatrick.

Emergency crews tore the roof off the car to remove the driver, said Fitzpatrick. He was the sole occupant, transit officials said.

At the time of the crash, the train was traveling at low speed because it was about to stop at the station, Gray said. The train T-boned the car.
