Three lanes of westbound Interstate 90 in Seattle were blocked after a wild end of a police chase that was caught on camera.

The incident, in which a trooper used a PIT maneuver twice, was recorded by a Department of Transportation camera and showed the truck spinning around both times it was hit Monday morning.

Trooper Chris Webb said the incident began when a trooper tried to stop the pickup for speeding and unsafe lane travel on Interstate 405 near I-90. The driver then exited to west Lake Sammamish before heading west on I-90.

Webb said two patrol cars were damaged.

The highest speed the chase reached was 73 mph.

Police said the driver, a man in his 40s, was believed to be under the influence of narcotics and was throwing items out the window during the pursuit.

KIRO 7 reporter Rob Munoz saw two large jars of marijuana inside the truck.

Traffic was backed up at least 6 miles while troopers investigated.
