Why Speed Limits Have Changed

This was then raised to 20mph and large fines were put in place for speeding and reckless driving. This to encourage safer driving, however as cars were developing and more people were driving  the speed limit had to change to 30pmh this rule was introduced in 1934 in built up areas. The speed limits were changed and introduced as more and more people were starting to drive motorcars and after the industrial revolution people needed to travel further.
