When you park on double yellow lines check for the two yellow lines across the ends of the kerb. If they are there you cannot park on any of those double yellows. Check the notices in the carparks where there are not a lot of disabled spaces, some of them allow you to park for free in the other spaces as long as you display your badge. Some of the charging car parks have a discounted fee for people with disabled badges. Best to have a read of the manual because that is the most up to date info. Just read a couple of pages at a time. My granddaughter has had one for many years as a child and now as an adult, and even she has to keep checking the manual . Just remember that no one can use it if you are not in the car. Unless they are picking you up or dropping you off.
