Dashcam footage has captured the shocking moment a tailgating driver ploughs into the back of another vehicle, causing a multi-car pile-up.
The video, which was recorded by a truck driver on a highway outside Williamsburg, Virginia, last week, shows at least seven cars smash into one another as they all desperately attempt to stop.
One car even shoots out in the next lane and hits another truck that had pulled on to the hard shoulder in an attempt to avoid the incident.
The trucker, named as Daniel Condon, uploaded the footage to YouTube with the comment: "The state troopers were extremely grateful for my dashcam video of an accident you are about to see.
"I was grossed out close to 80,000 lbs. I was fortunate I was able to stop my truck.
"The outcome could have been much worse.
"Thankfully, there was [sic] no serious injuries or fatalities. Please be careful out there, people."
