In various major Chinese municipalities, local government regulations establish 'Motorcycle Restriction Zones' (禁摩区 / 限摩区). What must a rider do regarding these zones?

1. Ignore the rules if the motorcycle has full 3C certification
2. Pay an on-the-spot toll fee to enter any restricted zone
3. Ride only on sidewalks inside restricted zones
4. Strictly comply with local signage, restriction hours, and boundary limits prohibiting motorcycle entry
