A safety belt system for paratransit lifts uses a front lift strap and a rear lift strap. The front lift strap and the rear lift strap are safety belts that can be connected in front of and behind a wheelchair that is mounted onto a lift platform of a paratransit lift. The front lift strap and the rear lift strap are identical, and each has a pair of length-adjustable webbings, a quick-release buckle, and a pair of lift-connection mechanisms. The quick-release buckle is connected in between the pair of length-adjustable webbings so that the two length-adjustable webbings are terminally connected to each other. Each lift-connection mechanism is terminally connected to a length-adjustable webbing, opposite to the quick-release buckle. As a result, the length-adjustable webbings can be connected to each other and then connected to the paratransit lift.
