Got pulled in Colchester many,many years ago by 2 'bules. 1 gets into the cab of my intercontinental Bedford TK whilst the other stands outside making handsignals at him, you know how many fingers etc. In the end they had to admit that my 7 strings of flags crisscrossed across the screen, 2 waving hands, 4 esso tiger tails and a couple of stickers didn’t obstruct my vision! Then they asked why. To aim it with I said and drove off. Thank God they didn’t check my log books!
