I got 46, but I got one wrong through being too courteous to other road users (when to stop using High Beam if you're being overtaken at night), one because I don't use Park and Ride and one because if I don't travel outside England, what does it matter that I won't see a Traffic Officer?!
I also sent them a complaint about one question because I think it's poorly worded:
It asked "What can you do to be seen more easily when you're riding at night?" and gives the following answers:
A. Use your headlight on dipped beam
B. Wear waterproof clothing
C. Keep the motorcycle clean
D. Stay well out to the right
I selected D and was told:
"You selected D, the correct answer was A
"It's vital to make yourself as visible as you can. Use the correct lights on your motorcycle. Wear reflective clothing and a light or brightly coloured helmet. Fluorescent clothing is effective in daytime, but won’t show up as well at night. Most high-visibility clothing will have a combination of fluorescent and reflective materials."
I think this is badly phrased. It is a legal requirement to use headlights at night, it's not something I "can" do, it's something I *must* do.
I selected D because, apart from that, positioning to the right was the best option to ensure that I am visible and less likely to be lost in "visual clutter" on the left of the road.
Of course, wearing Hi Viz is the best option (as well as making sure that my lights are working and clean), but that wasn't offered as an answer.
