Aggressive driver nearly causes collision, twice.

This occurred on 84 Westbound in the Danbury CT area.

Dashcam owner recalled hearing a horn but did not know what the issue was until the dashcam was reviewed later on.

Red car appears to be passing in the right lane trying to overtake and abruptly changes lanes without signaling and nearly colliding with truck who happened to be changing lanes as well.

Red car hits the breaks to avoid collision but then almost causes another one with the jeep behind him. He then completes the lane change and then aggressively moves over to the left most lane and seems to almost lose control when the car is seen moving quickly side to side.
