How did vehcles cross trenches?

Vehicles crossed trenches primarily through the use of bridging equipment, such as portable bridges or fascines, which were designed to span gaps. In some cases, specialized vehicles like tanks had tracks that allowed them to traverse shallow trenches directly. Additionally, engineers would often fill trenches with materials like rubble or earth to create a passable surface. In World War I, tanks were particularly effective at crossing trenches due to their armored design and capability to navigate rough terrain.
