Why can a two wheel off road motorcycle be street legal in Idaho and 4 ATV cannot legal?

ATVs are not street legal in Idaho because they do not meet the safety requirements for road use. ATVs are designed for off-road use, and they do not have the same safety features as motorcycles, such as headlights, taillights, turn signals, and mirrors. In addition, ATVs are not as maneuverable as motorcycles, and they are more likely to tip over.

There are several exceptions to the rule that ATVs are not street legal in Idaho. For example, ATVs can be used on public roads if they are:

* Being operated by a farmer or rancher for agricultural purposes.

* Being operated by a law enforcement officer or other government employee in the course of their duties.

* Being used for certain types of recreation, such as hunting, fishing, and snowmobiling.

* Being operated in an OHV park or designated trail area.

In order to operate an ATV on a public road in Idaho, you must have a valid driver's license and you must wear a helmet. You must also obey all the traffic laws that apply to motorcycles.
