Transport requires seven 20-foot container lorries, ten open trailer lorries, and one closed trailer lorry. Light tanks were much smaller and lightweight, allowing transport on lorries (trucks). Leyland diesel engines were used in Finnish Sisu and Vanaja lorries and buses in 1960s. The Danes mustered 33 buses, 14 ambulances, seven lorries and four private cars. Dodge started assembling lorries (trucks) in the United Kingdom from imported parts in 1922. One chassis was used for both lorries and buses. From 1912 lorries and other commercial vehicles were supplied. An extra checkpoint, solely open for Western bin lorries (garbage trucks), was opened there. The protesters blockaded the A16 with lorries and agricultural vehicles. The official category name is heavy-duty diesel engines, which generally includes lorries and buses. From then on, AEC became associated with both lorries and buses. Wreckers ("recovery lorries" in the UK) are used to recover and/or tow disabled vehicles. Modern cruiseferries have car decks for lorries as well as the passengers' cars. Dozens of automobiles and lorries were also lost. DAF dealers will sell Tatra off road lorries.
