Road works

Will be so glad when they finish the road works in our area.They have been working on it since June, and I am so over the guys who do not know the difference between a red and green flag, not to mention those that do not think any directions apply to them! I cannot count the number of times I have been given the green flag ( go, in my book) just to get confronted with someone half way down, who has ignored the red flag ( stop) and is blocking the road. Or you get the guys that really do not know what either flag means, and just stands there waiving both around at the same time! WT???
