While most people are able to park their car a long distance from a building and walk(which most people need to do more of anyway) people with mobility issues aren't able to. This means that disable parking spaces are a necessity in all car parks and need to be in a safe location near the entrance that is accessible and need to be bigger so wheelchairs can be gotten out of them.
In a lot of places there are too few disabled parking spaces and in some places the disabled parking spaces are the same size as a regular spaces which is too small to get a wheelchair out of. There is also a big issue of people parking in disabled spaces that aren't disabled, the reason they do that is that it is very rare to get punished for parking in a disabled space.
In Altnagelvin the disabled parking spaces are good as they are quite big but there are too few of them compared to the large number of parking spaces.
