Three people were injured in a head-on, four-vehicle collision Tuesday night on Martin Luther King Jr. Way on West Hill, according to the Washington State Patrol.

The driver of one of the cars involved, a 34-year-old Renton man, was booked into the King County jail for investigation of vehicular assault. He was one of those injured.

According to the state patrol, the Renton man was eastbound in the westbound lanes of Martin Luther King Way (State Route 900) near 57th Avenue South at about 10:30 p.m. when his 1993 Toyota Camry collided head-on with a 2002 Honda Civic driven by a 27-year-old Seattle man.

The Seattle man was taken to Harborview Medical Center in Seattle for treatment, as was a 27-year-old Seattle woman who was a passenger in his car.

After the collision, the Camry continued eastbound, colliding with a 1999 Toyota 4Runner, according to the state patrol. The 4Runner then collided with a 2005 Mazda MPV driven by a 26-year-old Renton man. Neither driver was injured.

Passengers in the Mazda were a 24-year-old Renton woman and two boys, ages 3 and 5.

The cause of the accident is under investigation, although the state patrol indicated that drugs or alcohol were involved.
