Hello
I have had this on my julies wheels facebook page for a while too, so my pupils have got to look at it.
Just as a point of discussion tho, (which I have also had with Mike Lally). I personally would go into a bus lane or over a white line, safely, even if it meant I was breaking the law to allow an emergency vehicle through. As I explained to Mike when my husband had a heart attack over a year ago now he was told had we waited for an ambulance he would have died.
I know you can be fined if you do it without the consent of a police officer but imo if that minute allows an ambulance or other emergency vehicle to get to where its going quicker, then that minute or so could save a life. A fine or a life... I know which one I would choose.
