Update: As of October 16, there has been 798 semi truck crashes*  in Washington State. At the same time last year, there had been 661.


Just in the last few weeks, there have been several major collisions that caused severe injuries—and kept thousands stuck in traffic for hours.

WSDOT-Semi-truck_rollover-CrashJune 9: Three semi trucks collided in Blaine, Washington, just south of the U.S.-Canada border. The Bellingham Herald reports that 2 drivers were hurt— one trapped in the truck for over an hour.

Then, a semi-truck rear-ended a Metro bus on I-5 in Seattle.

June 13: A semi rolled over on eastbound I-90, where ramps from both directions of I-5 merge. The truck driver was injured.

The same day, two people were hurt in a head-on collision between a car and a semi-truck in Covington.

June 16: Northbound I-5 in Tacoma was blocked for hours after a truck driver hit concrete barriers, turning the semi-truck sideways and spilling fuel on the roadway.

Back in March, after yet another truck crash log-jammed I-5 for hours,  I looked up the crash statistics for the year to date. See Part 1.  

At the time, I posited that the weather may have something to do with the uptick in truck crashes.

But it hasn’t seemed to slow down. Weather can’t be the only factor.



What do you think is causing this?

We should all want to know what’s happening on our roads.

If you have any thoughts on factors leading to this uptick in semi truck crashes, tell me.



* Coluccio Law does not refer to predictable, preventable semi-truck crashes as “accidents.”

See: We say “crash” instead of “accident”.
