Things go south quickly when a semi truck driver’s lane ends before they can merge safely, causing other drivers to swerve and crash.

Reddit user u/vulturulbradu shared the dash cam clip on September 26.

In the video, you can see a truck following a second semi moving over to apparently pass the first semi on the right. However, the lane ends and the second semi veers into the dash cammer’s lane to try to avoid a crash. The dash cammer also veers left to try to avoid the second semi, striking a passenger vehicle and causing it to lose control and nearly strike the first truck.

Check out the dash cam clip below.
