A lot of the FM roads here in Texas have speed limits of 65-75 mile per hour speed limits. If your hauling a load of water, oil or just a trailer full of farm equipment, coming over a hill or around a curve and into a cyclist or pack of
cyclists running 15 mph can put you in a ditch. That’s the absolute worst place to be riding bikes. In no way should they be allowed to share the same lanes as motor vehicles. In Texas you can be given a citation for impeding traffic, running 15 in a 45 to 75 definitely qualifies for impeding traffic.
Most of the FM’s around Wichita Falls have 6 foot shoulders and bikes ride on these shoulders.
If someone can’t keep off the shoulder when passing bikes, they are a terrible driver.
