A vehicle for delivering inflammable fluid, comprising a tractor unit and a tank mounted on a support towed by the tractor unit, the vehicle comprising a fluid circuit connected to the tank for filling and/or draining fluid, the fluid circuit comprising a set of pneumatic valves, the vehicle further comprising an electrical circuit comprising at least one electrical component of the support towed by the tractor unit, the vehicle comprising an electricity source detachably connected to the electrical circuit via at least one port for connecting to a connection interface, wherein:

• the connection interface comprises a movable cover that can move between a first position blocking access to the connection port(s) to prevent the electrical connection between the electricity source and the electrical circuit and a second position not blocking access to the connection port(s) to enable the electrical connection between the electricity source and the electrical circuit;
• the vehicle further comprises a switch connected to the fluid circuit and switchable between a first state enabling the operation of the set of pneumatic valves to allow filling or draining, and a second state preventing the operation of the set of pneumatic valves to prevent filling or draining;
• when the movable cover is in the first position thereof, the movable cover switches the switch or allows the switch to be switched to the first state thereof;
• when the movable cover is in the second position thereof, the switch is automatically switched to the second state thereof.
