Drivers are able to report aggressive behavior on state roads on a Web site, wsp.wa.gov.

"The guy cut off the person who was behind us and started to ride the back of us," said Jason Karlan.

Karlan and his girlfriend are thankful to be alive after an aggressive driver made obscene gestures, sped in front of him and slammed on his brakes, causing Karlan to crash.

"We just got hit and then hit again and then were on the side of the road," Karlan said.

Fortunately, nobody was killed in the multiple car pileup on Interstate 5 near Federal Way.

We've learned this spot is one of more than 300 aggressive driving hot zones in our state reported by drivers online during the past two months.

A majority of these hot zones are in the most populated areas of Snohomish, King, Pierce and Thurston counties.

Terry Kindle is one of the drivers who has gone online to fill out the state patrol's new "hot zone" reporting form, telling troopers specifics on when and where they've spotted aggressive drivers.

"I feel like it's a chance to help and I feel like it's a great opportunity to let the State Patrol know where these hot spots are," Kindle said.

Trooper Greg Pressel has a very personal reason to combat aggressive driving.

He was nearly killed in a crash caused by an aggressive driver he was trying to stop. It ended his motorcycle patrol career, but now he's analyzing the hot zone reports sent in from drivers.

So far the top hot zones include:

In Pierce County, Interstate 5 from 84th Street near the Tacoma Mall, north through Fife.

In King County, 320th in Federal way north to South Center.

In Snohomish County, a 12-mile stretch of I-5 between Lynnwood and Everett.

"The goal with this program is to save lives," said Greg Pressel of the Washington State Patrol. "If we save one life from this program, the program is successful."

To save lives, troopers are now running emphasis patrols in the hot zones, using unmarked cars to catch aggressive drivers.

"The reason I'm stopping you is because (of) your two lane changes without using your turn signal, and you followed too closely on one occasion," trooper Jason Blanker told one driver.

Just a few miles away, police recovered a sawed off shotgun and knives from another aggressive driver's car.

He triggered a wreck on Highway 512 that seriously injured the innocent driver in a pickup truck.

And back up Interstate 5, Jason Karlan says after becoming a victim of aggressive driving, he's glad to hear the state patrol has started the "hot zone" program to stop it.

"I think it will prevent a lot of crashes a lot of reckless driving."
