The State Patrol says a collision that caused miles of traffic backup on Interstate 5 near DuPont during rush-hour tonight and injured three people was caused by a driver changing lanes into another vehicle.
A 49-year-old Lacey man merged from the onramp near Center Drive and changed lanes into a Honda Civic driven by a 28-year-old Seattle woman.
The Honda spun into another lane and was struck by a Chrysler Sebring, which then hit the barrier and rolled over.
The Lacey man was driving on a suspended license and made an unsafe lane change, according to the State Patrol.
The accident, which occurred about 6:30 p.m., caused more than five miles of traffic backup on I-5.
