Okay, thanks for reviewing. We don't drive in London often, in fact, the last time we visited Southall was well over 5 years ago. I usually am very conscious of road signs, but in this instance, this was a very long straight stretch of road, and only towards the end did these signs appear. This is the first time I've come across something like this. I guess we'll have to pay the fine and take it as a lesson learned!
In terms of driving straight on, is it reasonable that we should stop mid-driving on a straight road to read signs? And then have to suddenly determine a change in direction at the point we would have been driving straight?
