At first I thought this was a 'near miss', but checking the video I'm pretty sure contact was made, and you hear the 'bang'. It's interesting neither vehicle stopped, both drivers must have something to hide!
The merge points at highway on ramps are always a problem, usually with somebody in too much of a hurry. A dash cam in your truck can help protect you, when things 'go wrong'. The Ausdom A261 is a nice dash cam, provided by GearBest.com, I'm currently using in my tractor trailer. It provides good day and night video, and is fairly easy to use.
This is a screenshot of an old Dodge pickup, pulling a trailer, which was later the cause of an accident when it forced it's way into an exit lane, which was already occupied by a small car.
The small car ran into a car to the right, to avoid getting hit by this pickup.
The pickup never stopped.
Watch closely to see this pickup and trailer appear from in front of the white box truck, and swerve into the exit lane.
This is video from my HP F200 Dashcam of an accident on the NY Thruway, 06-30-14, near Mendon, NY.
Watch the oncoming lane in the distance and you can see a straight truck veer across the median in the Eastbound lanes, and plunge into oncoming traffic in the Westbound lanes.
Two men in a Westbound pickup died in this crash, and 6 other vehicles were destroyed,or damaged.
