Yes, I appreciate that lorries can take a while to overtake other lorries on dual carriageways and it can be frustrating when they take about a mile to get past as the overtaking lorry is not much faster than the slower one.However this morning one belonging to Cowan Transport sat alongside another on the A38 from near Ripley to Derby, about 8 miles! The road is downhill or flat until near Derby and these lorries created a huge tailback of traffic. Totally pointless, how much journey time did the lorry gain?
