It seems the regulations are different for different areas, states, counties, cities and so on. So, if I have a Wa. drivers license and my car has all the smog goodies that make it legal here in Wa. but not enough to make it legal in Ca., I can still go to ca. and drive it as long as I have an up-to-date Wa. license and am a resident of Wa. Does this follow through with bicycles? In other words, though my bike is legal in my home state, can I ride it in a state where it may not be legal simply because I have a valid drivers license in Wa.? I think this question cannot be answered until the laws are made uniform throughout the states and overridden only in areas with posted signs to the contrary such as NO BIKES ALLOWED ON THIS TRAIL. As with cars, NO MOTOR VEHICLES ALLOWED. Motored bikes will eventually have to either be classified as bicycles or have their own classification throughout the United States. Am I correct?
