House File No. 566 is a bill proposed in the Minnesota House of Representatives that aims to modify the existing regulations related to the operation of all-terrain vehicles (ATVs) on public roads. The main points of the bill include:

1. Where ATVs Can Operate: The bill specifies conditions under which ATVs can be operated on the shoulders, banks, and ditches of certain public roads, particularly trunk highways, county state-aid highways, and county highways. It also allows ATVs to make left turns on these roads if it is safe under current conditions.

2. Local Authority Regulation: Local governing bodies (like counties, cities, or towns) can enact ordinances to allow ATVs on public roads under their jurisdiction for accessing businesses, residences, and making trail connections.

3. Restrictions: The bill outlines certain restrictions:

   • ATVs cannot operate on the roads mentioned from April 1 to August 1 in agricultural zones unless used for agricultural work transport.
   • Nighttime operation restrictions are set for operation within half an hour after sunset to half an hour before sunrise.
   • ATVs are not permitted on interstate highways or freeways at any time.

4. Special Permissions:

   • The bill enables the operation of ATVs on certain roads for agricultural purposes and by certain authorities and utility workers for official duties and tasks.

5. Environmental and Safety Measures:

   • The Commissioner can limit ATV use in rights-of-way if degradation of nearby vegetation, water siltation, safety threats, or other issues are identified.

6. Notification Requirement: If restrictions are imposed due to safety or environmental concerns, the Commissioner must notify the relevant road authority with reasons and duration of the closure.

This bill aims to balance ATV usage with safety, environmental protection, and local control over their roads.
