A public transit vehicle has a passenger entrance ramp at a door way including a support frame for mounting on the vehicle at the doorway carrying a primary ramp panel, a secondary ramp panel and a fixed platform panel. The primary panel is pivotal through 180 degrees between a retracted position inverted within the vehicle and covering the secondary panel and the fixed platform panel and a deployed position in which the primary ramp panel is inclined from an inner edge downwardly and outwardly from the vehicle to an outer edge at the ground. The primary panel is pivoted at its inner edge on an outer edge of the secondary ramp panel pivotal which is in turn pivotal about an inner horizontal axis at its inner edge. The primary and secondary ramp panels are thus arranged such that, in the retracted position, the outer edge of the secondary panel is in the raised position so that both the primary and secondary ramp panels are substantially horizontal and, in the deployed position, the outer edge is moved to the lowered position so that the primary and secondary ramp panels form a common ramp surface inclined outwardly and downwardly from the inner edge of the secondary ramp panel to the outer edge of the primary ramp panel.
