or
if it is safe to or even feasible to go around the obstacle, do you do that and let the inconsiderate people/person that caused the problem to you in the first place so they feel free to do it again.
In my case when I got help from the 2 members of the public since it was not possible to go around the road signs because the kerb was just too high for me to get off with my scooter, nor was the pavement wide enough for me to be able to turn around on it. So I would have had to have phoned the police which is a good job I carry a mobile phone with me.
What would happen to someone who didn`t have a mobile phone with them!
I also had a problem trying to go along Lumphinnans Road thinking I would go to Aldi`s on my scooter. I`ve been going along Lumphinnans Road taking my dog Jasper for a walk on the South side of the pavement quite a lot but due to the road works I was able to see from a distance that the pavement was blocked so I went along the North side which was clear or at least I didn`t see any Blockages until I went round the corner into Robert Smith Court. There were normally dropped kerbs but due to the Road Works they were too high to use so I had thought that all I would have to do is go further into Robert Smith Court to cross there to be able to continue along the Road, but no, hidden around the corner was a big road sign across the path. On this occasion I was able to turn around and head back home.
