The Tri-Cities region has seen three fatality collisions in the time span of one week.

Washington State Patrol troopers said they noticed a common theme after investigating each crash.

Troopers said in each of these fatal car crashes, the driver was not wearing their seatbelt.

One woman died after a violent car crash in Pasco on Sunday, Sept. 5. Another man was pronounced dead at the scene of an accident in Walla Walla on Saturday, Sept. 11.

On Sunday, Sept. 12, another man died after a rollover wreck in Richland.

None of these drivers were wearing seatbelts.

Last week, medics rushed another driver to the hospital with serious injuries after he was ejected from his car because he wasn't wearing one.

While wearing a seatbelt doesn't guarantee anything, troopers said it helps your odds of not getting seriously hurt in the case of an accident.

"Buckling up inside of your vehicle will help you stay inside during a collision or rollover crash," WSP Trooper Chris Thorson said. "If you're not, you have the chances of being partially or even fully ejected from the vehicle."

Trooper Thorson said wearing a seatbelt not only protects the driver and passengers, it's the law.

He said Washington state has one of the highest compliance rates of seatbelt usage in the nation and he wants to see it stay that way.
