Mopeds and Scooters are not against the law in lake St. louis. BUT they are not allowed on the Meadows shoping center. The HR has worked really hard at building good relationships with the different police departments in st charles county by riding safe and obeying all laws. Be careful having an no liscensed person ride a moped on the streets its a serious offense if he gets caught. Be safe!
