1. An access ladder for a vehicle, comprising two or more steps, vertically superposed on each other, each of which comprises a main surface wherein the projection on a horizontal plane of the main surface of each step protrudes at least partly from the projection on a horizontal plane of the main surface of a step above wherein, with the exception of a lower step, the main surface of each step has a window at one end of the step whose projection on a horizontal plane disposed in a front to rear direction of the vehicle overlaps a portion of a step below, wherein the orthogonal projections of the steps remain inside the orthogonal projection of the lowest step, and each window is made on a front edge of the respective step.
