Which vehicles does this sign prohibit from entering?

# Explanation The sign prohibiting entry to motorcycles specifically prohibits access to **motorcycles and three-wheeled vehicles assimilated to motorcycles** (such as motorized tricycles). This restriction does not include mopeds, which are vehicles of smaller engine displacement and power, and which may travel in areas where motorcycles are prohibited. It is important to distinguish between these types of vehicles to properly comply with road signage.
