Just thought I'd share with you what happened to me yesterday ...
Yesterday morning at about 10:30am on a dual carriage way (A55) I noticed a green fluorescent jacket in the distance and a blue light flashing. As I got nearer there were cones placed right in the middle of the road with a police man right at the end, and his car further behind. I didn't have a clue what was going on, so I slowed down assuming he would give me some hand signals to tell me what to do.
At first he didn't even look, and there were no signs telling me which lane to use. I moved to the right hand lane, he looked over and waved frantically which I thought there must have been and accident and he was telling me to stop. I slowed right down and he was still waving like a crazy man, I really didn't have a clue what to do. He seemed to be pointing more towards the left lane so I moved over .. as I did this to my surprise he threw his coat on the floor in frustration exactly like a kid throwing a toy out of a pram

Now, my thinking here was why they hell did he not put a sign in the left lane pointing towards the right or block off one lane like they do usually?! Bloody idiot.
