State transportation officials are sharing more information about what was happening just before the 75 car pileup in Etna last week. According to WGME the Maine DOT says those flashing hazardous-weather speed limit signs are also collecting information about how many cars are on the road and how fast they're going. Data from the signs shows drivers were going about 55 miles per hour, that’s 10 miles an hour over the posted speed limit of 45 miles per hour. At least one driver in the area of the wreck was going at least 72 mph. State police call the 75-vehicle pileup the largest chain-reaction crash in Maine history. (WGME)
