Reduce speed limit outside Haygrove school

Currently the speed limit outside Haygrove School, Bridgwater is 30mph. I think it would be beneficial to change the speed limit to 20mph. This is a road that needs to be crossed by many students immediately after they leave school. Not only would this ensure students have a safe walk to and from school, it would encourage them to walk which has a positive impact on the environment. However, parents drop children off directly outside school which can become unsafe for other drivers and children.
