Abstract: A driving handover control device includes a memory and a processor coupled to the memory. In a case in which driving is handed over from a first state in which a vehicle travels in accordance with instruction from a first remote operator of the vehicle to a second state in which the vehicle travels in accordance with instruction from a second remote operator who is different from the first remote operator, the processor implements a transition from the first state to a third state in which the vehicle travels autonomously without instruction from the first remote operator or the second remote operator, and, after the transition from the first state to the third state, implements a transition from the third state to the second state.

Abstract: A fuel cell vehicle includes a lid, a switch, a sensor, and circuitry. The lid opens and closes a fuel inlet through which fuel gas is to be supplied to a tank. The switch takes an opening position to open the lid and a closing position to close the lid. The sensor detects whether the lid opens or closes the fuel inlet. The circuitry is configured to prohibit the fuel cell vehicle from travelling when the sensor detects that the lid opens the fuel inlet while the switch takes the opening position.
