A vehicle has an electric or hybrid-electric traction drive supported by an ungrounded vehicle frame. The vehicle also has a current collector, which can be electrically connected to the traction drive and which can be brought in galvanic contact with a contact line of a grounded contact-line system to supply traction energy. The vehicle contains an electrical protection system for avoiding dangerous contact voltages on the vehicle frame or on a vehicle part connected to the vehicle frame in a conductive manner. The protection system has a first protection stage, a second protection stage, and a switching element, by which the protection system can be switched between the first and the second protection stages. The first protection stage provides greater safety from dangerous contact voltages than the second protection stage. Thus, a protection system can be provided which provides sufficient safety in all operating states of the vehicle.
