Then there's the entertainment as three lanes (sometimes even four) try to head down the 414. Despite the signage clearly pointing out that L1 heads into L1, L2 into L2, L3 & 4 round the r'a'b, the usual pattern is that L2 heads into L1, L3 (sometimes L4) into L2, and gawd help the poor sod who's actually following the markings in L1.

In other words, all 4 cars should have circulated throughout in L1. The fault occurred before entry. >> If you entered from the south in L2, where would you make your lane >> change?

That's nonsense. It is worse even than circulting in L1 because a lane meander often causes a waiting driver to make a false start or to late brake after initially assuming it is possible to keep rolling.

They are following Highway Code rule 186 to: keep to the right on the roundabout until you need to change lanes to exit the roundabout even though it would be quicker and shorter to move change lane just as they exit. Where does the HC say to spiral out?

DavidR expressed precisely : > In other words, all 4 cars should have circulated throughout in L1. I did not say that! Unless there is good reason not to, the lead car in that picture should have moved over to L1 - there was no reason for him/her not to. Using L1 when going 3/4 way round would be wrong, but we don't know where these cars actually entered the roundabout from. Holding onto L2, without a good reason to do so, is a constant source of frustration on the road. > The fault > occurred before entry. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |
