Deputies are trained to stop chasing vehicles when they travel the wrong way on highways and one-way streets.
Washington State Patrol troopers say almost every wrong-way driver on I-5 ends up hitting multiple cars, and many incidents turn deadly.
A wrong-way driver died in January when she slammed into an ambulance head on, injuring everyone inside including the patient.
The deputy's supervisors believe he may have saved lives by slamming the car to a stop.
"That's my initial feeling," Odegaard said. "Just looking at the traffic here on a car doing 120 miles an hour hitting I-5 southbound, people can't anticipate that car coming at you."
Odegaard said the suspect, who ran from the crash scene and fought with deputies, was wanted on multiple felony warrants.
A female passenger who was injured in the collision was identified as the suspect's cousin. Deputies said she was trying to get out of the car during the chase so the suspect may also be charged with unlawful imprisonment in addition to felony eluding and assaulting an officer.
