While big truck might be equipped with big brakes, that isn’t to say that these things can lay into the braking system over long periods of time. It might just happen that the friction eventually gets to them and causes too much heat which causes the systems to fail in a hurry. This is why you see the runaway truck ramps on roads that have quickly changing altitude.
This time, we check in as a runaway truck actually does have to use one of these ramps and the scene is nothing short of terrifying as this braking failure really comes to life.
We join in on the scene as a following car chases the semi truck with smoke flowing out from underneath it as the brakes have failed or are coming incredibly close to it.
