Unusually tonight I had to filter on the A14, not that filtering on the A14 is unusual in itself, but doing it eastbound in the evening is. After a few miles, roughly where it crosses the river Cam, the cause turned out to be a couple of lorries wedged together in lane 2. So I negotiated the suspicious oily-looking stain that was spreading across lane 1 carefully and carried on my merry way. A few miles further on, I took the exit for the A1303. In the dark, my eagle eye detected a police vehicle coming the other way. It wasn't hard to spot: it had all flashy lights lit, alternating main beam headlights included. Oh, well, the accident must've been worse that I thought. Because of the glare, I and the car in front slowed. Shortly afterwards another police car came by, also blinding us, well, me anyway, forcing us to slow down further. Oddly, he wasn't in a rush to get to the incident and seemed to pass a bit bloody close TBH. At this point it dimly filtered through that they were not in fact heading for the crash but were, in their dazzling way, trying to tell us something, but no sirens were used or anything. The message was made clearer by a police bike that was flashing its blue lights but was considerably less dazzling. As we approached this chap slowed until he was almost stationary, right on the centre line but gave no other visible signals. Finally, as I passed him, I saw a bloody huge motor yacht being transported on a flatbed trailer. Huge hardly does it justice: its beam alone was easily fifteen feet, probably closer to twenty. Following this was a vehicle with large clear "abnormal load" sign. Now I'd have thought that oncoming traffic would need more advance warning than following traffic, and it would have been miles better to put the warning vehicle at the front, not force oncoming traffic to slow down by damn nearly blinding them. Grrr.
