i was heading to clarksville on highway 48 and i was behind a TDOT truck who was diving slowly i was trying to go around him at one point but there was a car coming and after that car left the double lines can up so i couldnt pass and the there a straight away where i can pass and he went to the shoulder of the road i thought he was gonna let us pass him but there was a driveway to the left that i didnt see and i didnt see his blinker so about when i got to his rear wheels he turned left i slamed on my brakes and went left but he hit me and i went into a ditch
