A  six-vehicle crash on I-84 Wednesday evening has resulted in charges for a tractor-trailer driver.  State Police say the 29-year-old truck driver was at fault and issued an infraction for following too closely.  The trucker rear ended a Porsche around 7:30pm westbound just past exit 10 as the car slowed in the construction zone.  The impact led to a domino collision into 4 vehicles in front of the Porsche.  All 6 vehicles were towed from the scene, and five people were transported to Danbury Hospital for treatment of non-life-threatening injuries.
