11.1. No person may operate a vehicle propelled solely by an electric motor elsewhere than on private land, unless the vehicle is equipped with a triangular orange warning sign having a red reflective edge and complying with Standard ANSI/ASAE S276.6 published in January 2005 by the American Society of Agricultural Engineers or any subsequent amendment to that standard.
The sign must be attached with an angle of the triangle pointing upward, vertically and perpendicular to the direction taken by the vehicle, as close as possible to the rear, at the centre of the vehicle or as close as possible to the left, at a height of not less than 50 cm or more than 150 cm measured from the ground to the base of the sign.
The sign must be in good condition, securely attached to the vehicle and free from any object or matter that could reduce its visibility up to a distance of 180 m.
