Large vehicles can block your view. Your ability to see and to plan ahead will be improved if you pull back to increase your separation distance. Be patient, as larger vehicles are subject to lower speed limits than cars and motorcycles. Many large vehicles may be fitted with speed limiting devices which will restrict speed to 56 mph (90 km/h) even on a motorway.
