Engineering and Architecture made this really short but very educational compilation displaying vehicles making emergency stops on a runaway truck ramp that’s packed with dirt to consume the energy of a crash, making for a controlled exit, and keeping damages to a minimum. This ramp produces a safer environment for both the motorists who can’t stop for any reason and for those driving near them.
A runaway truck ramp is a traffic device that enables vehicles, which are having braking problems to safely stop. It is typically a long, sand- or gravel-filled lane connected to a steep downhill grade section of a main road, and is designed to accommodate large trucks or buses.
