<p>The invention relates to a signalling device for lorries (1) which are provided with a loading flap (2). During the loading and unloading of lorries the loading flap, which is in the horizontal position in line with the loading floor (5), extends beyond the lorry, and thus constitutes a hazard for other traffic. In order to warn the traffic, the invention proposes a signalling device comprising at least one arm which is fitted at the side where the loading flap is situated and extends in the horizontal direction, and which bears a warning light (13) at the free end. The arm comprising a drive means (7,8) which is operated in such a way through the movements of the loading flap that the arm is only in the extended position when the loading flap is in the horizontal position in line with the loading floor. Two of such arms are preferably present, each near a side of the loading flap, under the vertical projection of the loading flap. <IMAGE></p> |
