This format is now common across Europe as it is able to meet the EU maximum weight limit of 40,000 kg (88,000 pounds) without overloading any axle. The most common combination used in Europe is a semi tractor with two axles and a cargo trailer with three axles, one of which is sometimes a lift axle, giving 5 axles and 12 wheels in total. In Europe, usually only the driven tractor axle has dual wheels, while single wheels are used for every other axle on the tractor and the trailer. The major disadvantage is that for repairs on COE trucks, the entire cab has to hinge forward to allow maintenance access. Furthermore, it offers greater maneuverability in confined areas, a more balanced weight-distribution, and better overall view for the driver. This allows shorter trucks with longer trailers (with larger freight capacity) within the legal maximum total length. European trucks, whether straight trucks or fully articulated, have a sheer face on the front. The main difference between tractor units in Europe and North America is that European models are cab over engine (called 'forward control' in the United Kingdom), while the majority of North American trucks are 'conventional' (called 'normal control' or 'bonneted' in the UK).
