The invention provides a vehicle safety belt and a vehicle safety belt device; the vehicle safety belt is connected between a safety belt buckle and a coiler, and comprises a safety braid and a magnetic layer; when the vehicle safety belt is completely buckled, a real safety braid extension length pulled away from the coiler is bigger than a preset extension length; a safety braid safety belt buckle position is a first monitoring end; a position, having the preset extension length from the first monitoring end, of the safety braid is a second monitoring end; the safety braid between the first and second monitoring ends is a monitored zone; the magnetic layer is arranged in the monitored zone of the safety braid. The vehicle safety belt device comprises the coiler, the safety belt buckle, a monitoring module, the safety braid, and the magnetic layer; the monitoring module comprises a Hall element and a prompt element; when the Hall element senses the magnetic layer, a first electric signal is outputted so that the prompt element displays a first state; when the Hall element cannot sense the magnetic layer, a second electric signal is outputted so that the prompt element displays a second state.
