I'd be more concerned at how the lorries were doing 68mph ??Hardly relevant peter I'm traveling at 74mph speedo reading middle lane, the lorry I have just overtaken was traveling at 68mph speedo reading inside lane the next lorry ahead of me inside lane is also traveling at 68mph indicated. The outside lane is clear. What gap between the two lorries would you allow before I am accused of being a lane hog. Then we have the most important factor of all...........Where are you, what speed are you traveling at and what is your intention....simple question as the highway code doesn't make it clear..
