This might belong in the road section, but I often ride my mtn bike from trail to trail via highways/ roads, and I thought it might get more replies here. I ride mostly in AR and OK. I have heard that a bike is recognized as any other vehicle by law in OK, but that is only hearsay. I do remember a couple years ago in Tulsa, a small group of roadies were hit by a car. One of them died. The lady that hit them was passing in a no-passing zone and was held liable, if I remember right. Maybe 1oldroadie will see this and confirm.
How are your laws? And how can I find out for certain the laws in OK and AR?
There is a week long ride here in OK every summer called "Freewheel", usually about 2,000 riders and 500-600 miles. It is usually escorted by a Highway Patrol, and the last time I did that tour the officer made us (actually tried to make us) ride single file. I've also heard the law states no more then two riders abreast.
