Function
The sump buster uses a non-mechanical solid mass of concrete (sometimes other aggregates or metal) to demobilise a vehicle when access to a restricted area is attempted. When (for instance) a car attempts to transverse the sump buster, the device will demolish the vehicle's oil pan (literally "busting the sump"). The track (distance between wheels on either side of the vehicle) and ground clearance on permitted vehicles (usually, but not restricted to buses) is such that they may clear the device with ease. In some cases, advisory or mandatory speed limits are given.
