Step-by-step explanation:
Motorcyclists are advised not to drive in the center lane(s) of roads that have 3 or more lanes because it can be dangerous. One reason is that motorcyclists don't have a blocking position when there are lanes on both sides of the motorcycle. Riding in the center lane can make it harder for other vehicles to see the motorcyclist, increasing the risk of accidents. Additionally, the center lane may have more gravel or debris which can be hazardous for motorcycles.
