VIDEO: Trucker’s dash cam backs up fellow driver when four wheeler causes crash

Keep your dash cam rolling -- it could help someone else.

One trucker uses his dash cam to help a fellow driver who was caught up in a crash initiated by a car driver running a red light.

YouTuber Caught On My CCTV Cameras not only caught the crash on camera, but he also provided detailed analysis of the crash video.

The dash cammer writes: “Silver car runs red light while semi truck is in the intersection, forcing truck to take evasive action.

The truck’s evasive maneuver causes it to collide with a green car. The silver car proceeds down the road and gets in the left turn lane in a seeming attempt to leave the scene of the crash, but the dash cammer isn’t having it. He pulls his rig in front of the silver car, stopping it from leaving the scene.
