What happens when Minnesotans crash into steel cables on freeways


The Minnesota Office of Traffic Engineering uses the latest technology to reduce critical accidents on Minnesota freeways. They’re responsible for things like rumble strips, reduced conflict crossings, and the steel cables you see on the sides of Minnesota’s freeways.

Below is a video from the Minnesota Department of Transportation Facebook page showing how this technology reduces the severity of accidents. The footage they shared focuses on the steel cables and shows what happens when Minnesotans crash into them. It’s pretty wild to see what happens.

MnDOT video shows what happens when Minnesotans crash into steel cables

You’ve no doubt seen the steel cables zipping up and down Minnesota’s highways, and you’ve probably wondered if they really are strong enough to stop a vehicle.

The science behind the steel cables is really cool.

The Minnesota Department of Transportation explained on its Facebook page how the cables work to keep you and me safe.

High voltage cable center barriers consist of four steel cables attached to metal posts. When a vehicle hits the barrier, the posts break and the cables bend, absorbing much of the kinetic energy of an impact. The cables redirect the vehicle along the median, preventing an impact across the median and reducing the severity of the impact.

Watch the video below to see how the cables protect the driver and other motorists from serious or fatal accidents.

On your next drive, keep your eyes peeled and you’re likely to notice even more safety innovations that have been introduced to keep you and your family safe.
