The English name for that kind of barrier is "speed bump" I suppose.
- Wrong. Its barrier=sump_buster. Although reduced speed is recommended, that is not the intention of a 'sporsluse'. A 'sporsluse' there to prevent normal cars from passing. It does this by targeting low parts of your vehicle like the sump or the differential. It will eihter stop you or make substantial damage to these parts. --Gorm 14:42, 11 July 2012 (BST)
