In Wisconsin, Riding 2×2 is Legal
Untrue – “Riding Two by Two Is Illegal”
This is one you may not hear from fellow cyclists, but rather from helpful drivers “sharing” the road with their two-wheeled compatriots. In most states (39, to be exact), you are legally allowed to ride two abreast. However, the details do vary state by state and municipality to municipality. It’s a good idea to research what the law says where you live, or in places you’ll be traveling. … In general though, it’s OK to ride two by two as long as you’re not impeding traffic.
