Analysis by the Legislative Reference Bureau
This bill makes numerous changes to laws relating to all-terrain vehicles
(ATVs), utility terrain vehicles (UTVs), off-highway motorcycles (OHMs), and
snowmobiles.
Careless operation of an ATV or UTV
Current law prohibits a person from operating an ATV or UTV in any careless
way that endangers the person or property of another. The bill prohibits a person
from operating an ATV or UTV in any careless, reckless, or negligent manner so as

to impair the life, person, or property of another. Under the bill, for a violation of this
prohibition that results in impairment of the property of another, the court may hold
the defendant liable for treble damages, to be recovered by the person responsible for
maintenance of the property, and may order the defendant to restore, rebuild, repair,
or replace the property.
ATV and UTV operation on bridges
Under current law generally, a person may not operate an ATV or UTV on a
highway. However, a person may operate an ATV or UTV on the shoulder or roadway
of a highway to cross a bridge that is no more than 1,000 feet long if the operation
complies with a local ordinance that applies to the bridge. Current law requires that
such an ordinance requires a person to stop his or her ATV or UTV before crossing
the bridge. The bill eliminates the 1,000-foot limitation and the requirement that
a person stop before crossing the bridge.
Ordinances authorizing ATV and UTV operation on highways
Under current law, a city, village, or town (municipality) may enact an
ordinance to authorize the operation of ATVs and UTVs on a highway with a speed
limit of 35 miles per hour or less that is located within the territorial boundaries of
the municipality, regardless of whether the municipality has jurisdiction over the
highway. The bill eliminates the requirement that the highway have a speed limit
of 35 miles per hour or less.
Emergency operation of ATVs and UTVs
The bill provides that ATVs and UTVs may be operated on any roadway if the
operation is for emergency purposes during a period of emergency declared by the
governmental agency having jurisdiction over the roadway.
Authorized emergency vehicles
Under current law, “authorized emergency vehicle” is defined to include
vehicles operated by various entities, such as law enforcement officers, fire
departments, conservation wardens, and ambulance services. The bill expands the
definition of “authorized emergency vehicle” to include ATVs, UTVs, and
snowmobiles operated by these same entities and to include off-highway
motorcycles operated by law enforcement officers and conservation wardens.
Patrol vehicles
The bill creates definitions for “patrol all-terrain vehicle,” “ patrol utility
terrain vehicle,” “patrol off-highway motorcycle,” and “patrol snowmobile,” which
are ATVs, UTVs, OHMs, and snowmobiles that are owned or leased by a city, village,
town, county, state agency, federal agency, federally recognized American Indian
tribe, or public safety corporation, used for law enforcement, fire fighting, or
emergency medical response, and equipped with required sirens and lights. The bill
exempts patrol ATVs, UTVs, OHMs, and snowmobiles from certain operation
limitations such speed and proximity to highways while responding to emergencies
or violations of the law, subject to specified use of sirens and lights.
Revision to highway maintenance manual
Under current law, no state trunk highway or connecting highway may be
designated as an ATV route without DOT approval. DOT standards for ATV route

approval are detailed in DOT's Highway Maintenance Manual (HMM), which
includes policies, technical information, administrative direction, and operational
information for administration of DOT's highway maintenance program. The HMM
currently provides that requests for ATV routes or trails to use short segments of
state trunk highways for the purpose of connecting to businesses may not be
approved. The bill requires DOT to revise the HMM to remove these provisions.
