The concept of containment kerbs is to safely redirect vehicles away from danger returning them to their intended route. Unlike crash barriers, containment kerbs remain undamaged and cause no damage to vehicles. Camel Kerbs have a 2 stage system for redirecting vehicles, initially the lower inclined face of the kerb compresses the vehicles suspension and the axle guides the vehicle back onto the highway.
Ultimately if needed the round upper profile of the kerb exerts a lateral force on the vehicles tyre walls positively directing the vehicle back onto its intended path.
