Couplable automotive road vehicle comprising: • a set of front wheels comprising two wheels and a set of rear wheels comprising at least one wheel; • a chassis comprising a front part, on which the set of front wheels is mounted, and a rear part, on which the set of rear wheels is mounted; • an articulated connection device, interposed between the front and rear parts of the chassis, and allowing the front part to pivot relative to the rear part about an articulation axis normal to a running plane of the vehicle; • a steering device able to modify the turning angle of the two wheels of the front set, this steering device being able to be activated independently of the articulated connection device; • front and rear couplings, respectively located at the front and at the rear of the vehicle; the front coupling being alternately movable between: - a coupled position, in which this front coupling engages with a rear coupling, identical to the rear coupling of this vehicle and located on another vehicle, in order to mechanically attach, without any degree of freedom for yaw rotation, these vehicles together, and to align the front part of this vehicle with the rear part of the other vehicle; and - an uncoupled position, in which these vehicles are detached from each other; the rear coupling being alternately movable between: - a coupled position, in which this rear coupling engages with a front coupling, identical to the front coupling of this vehicle and located on another vehicle, in order to mechanically attach, without any degree of freedom for yaw rotation, these vehicles together, and to align the rear part of this vehicle with the front part of the other vehicle; and - an uncoupled position, in which these vehicles are detached from each other, a wheel cylinder being defined as being the cylindrical geometrical shape surrounding the two front wheels when they are not turned and extending transversely between the two front wheels, characterized in that: • the front part of the chassis comprises a chassis beam extending parallel to the axis of the wheel cylinder and disposed behind the front wheels, outside the wheel cylinder; • the front coupling comprises a yaw rigid coupling module mounted on the chassis beam between the two front wheels, this module having a coupling axis substantially coaxial to the wheel cylinder; • the vehicle comprises, for each front wheel: - a suspension arm mounted on the chassis beam and extending around the wheel cylinder from above; - a control tie rod for the steering device controlling the pivoting of the wheel in order to modify the turning angle of the wheel, this tie rod being located above the wheel cylinder. • a set of front wheels comprising two wheels and a set of rear wheels comprising at least one wheel;
