SEATTLE -- Attention tailgaters: State troopers are keeping an extra close eye for you this week.

WSP is holding a tailgating emphasis patrol Tuesday through Thursday.

The patrol said it investigated 9,500 collisions last year caused by drivers following too close.

The fine for tailgating is $136. It goes up to $187 if you caused a crash for following too close.

Troopers remind you to increase your following distance as your speed increases -- especially in wet or foggy weather.
