Snow-clearing trailer with means for detecting a third-party vehicle

A snow-clearing trailer (1) intended to be towed by a towing vehicle (3) with a towing hitch (4), said snow-clearing trailer (1) comprising:

• a chassis (5) extending longitudinally in a chassis direction (I-I) between a chassis anterior end (5a) and a chassis posterior end (5b), and developing transversely between a chassis first side (5c) and a chassis second side (5d) which are opposite one another,
• a snow-clearing blade (6) borne along the chassis first side (5c),
• at least one wheel (7a-7d) designed to support the chassis (5) on the ground, an axle of said wheel (7a-7d) being selectively orientable by orientation means (8) between a first wheel position, in which an axis of the axle about which the wheel (7a-7d) rotates is perpendicular to the chassis direction (I-I), and at least a second wheel position, in which the axis of the axle about which the wheel (7a-7d) rotates makes with the chassis direction (I-I) an axle angle (A) greater than 90°,
• a drawbar (9) able to connect the chassis anterior end (5a) to the towing hitch (4) of the towing vehicle (3),
• wherein said snow-clearing trailer (1) comprises detection means (10) able to generate a presence signal when:
• the wheel (7a-7d) is in a second wheel position, and
• an object or an individual is stationed in an area (A1) to the side and/or an area (A2) to the rear of the chassis second side (5d).
