Question Time. (Don’t Google it or look in the book. You wouldn’t be able to do that on the road. You have to make a decision). You can cross Double Solid White Lines to overtake which of these? 1, A pair of cyclists travelling together at 20mph. 2, A farm tractor travelling at 15mph. 3, A road maintenance vehicle travelling at 10mph. 4, A car towing a caravan, which is following a cyclist uphill travelling at 5mph. If you make a wrong decision, it could mean points on your licence!! Have a go! (THE QUESTION IS ABOUT CROSSING DOUBLE WHITE LINES, IN GENERAL. NOT SPECIFICALLY ABOUT THIS PICTURE).
