Discription of Events: I was driving on Route 50 in a 55 mph speed zone during moderate traffic conditions. I was in the left lane when two trucks approached at a dangerously high speed. One of the trucks (which I managed to photograph) suddenly merged from the right lane into the left lane without signaling. In doing so, it nearly sideswiped a vehicle in the right lane and came extremely close to hitting my vehicle as well. The truck forced its way between our cars, squeezing into a dangerously small gap. Both I and the driver in the right lane had to swerve abruptly to avoid a collision, which nearly sent us into the shoulder. This was an extremely reckless maneuver that put multiple drivers at serious risk.
