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. The ramp allows a moving vehicle's kinetic energy to be dissipated gradually in a controlled and relatively harmless way, helping the operator to stop it safely without a violent crash.

Nice setup, even has a crane to lift the trucks. Someone was thinking when they designed that. Great job! As a retired truck driver,I can attest to the fear a driver feels when his brakes fail.Had that happen to me when the municipality I worked for decided I should use a truck with hydraulic brakes that been sitting for over a year.The brake lines had rotted to the point that the brake fluid literally started spewing out as I was making my way through a high traffic area.Thankfully I could gear the truck down to a stop.I was sweating pretty good by the time that drive ended.   On a motorway back in the 80's going on holiday, I remember my dad calmly saying the breaks had failed on our VW fastback. He managed to get it neatly parked at a service station without incident, and we had to let the overheating break pads cool down before we could carry on to somewhere and get it looked at asap. Can't imagine the level of anxiousness when it happens to a truck driver.  I saw an out of control large 6-wheel tourist bus that went into one of these gravel ramps once, when it was being lifted out.    It must have been a pretty spectacular event.    The tourists still got hurt (no seat belts) and the bus was a write-off. It had remained upright and had not a scratch on it from about 1200 mm upwards.   But the gravel had abraded and torn off most of the suspension and wrecked the rear-mounted engine.  I was going past one of these gravel-filled ramps in England years ago; it was either near the Devil's punchbowl, or the South Downs. It was a lovely summer's day, so a car driver had decided to park in the middle of the ramp and enjoy a picnic with his family! He couldn't work out why everyone was giving him looks.  That's pretty cool and innovating. Wish the world would take more actions like this instead of it just being a certain country.
