Speed limit

A road speed limit is the maximum speed allowed by law for road vehicles. Speed limits are commonly set and enforced by the legislative bodies of nations or provincial governments, such as countries within the world.

The first maximum speed limit was the 10 miles per hour (16 km/h) limit introduced in the United Kingdom in 1861.

The Isle of Man is the only place in the world that does not have a general speed limit. In Germany, over 50% of the autobahn system remains free from speed limits.

Currently, the highest posted speed limit in the world is 140 kilometres per hour (87 mph) on Polish motorways , although a variable speed limit up to 160 kilometres per hour (99 mph) was permitted experimentally on a stretch of Austrian motorway in June 2006.
