SUMMARY:
Senate Bill 682 would amend the Michigan Vehicle Code to prohibit operating a vehicle,
bicycle, or other device at a speed greater than 15 miles an hour on a state trunkline highway
in a political subdivision that prohibits the operation of nonemergency motor vehicles by
ordinance, regulation, or resolution—or at a speed greater than 10 miles an hour in a business
district in such a political subdivision. (The bill is referring to Mackinac Island.) However, the
15-mile-an-hour limit on a state trunkline highway would not apply to a snowmobile as defined
by the bill. An individual found in violation of the bill would be responsible for a civil
infraction and subject to a civil fine of up to $100.
Proposed MCL 257.628
FISCAL IMPACT:
Senate Bill 682 would have an indeterminate fiscal impact on the state and on local units of
government. The number of individuals that would be responsible for a civil infraction under
provisions of the bill is not known. Under section 909(1) of the Michigan Vehicle Code, civil
fine revenue would be applied to the support of public and county law libraries. In addition,
under section 907(13) of the Michigan Vehicle Code, for any civil fines ordered to be paid, the
judge or district court magistrate is required to order the defendant to pay a justice system
assessment of $40 for each civil infraction determination, except for parking violations.
Revenue deposited into the state’s Justice System Fund supports various justice-related
endeavors in the judicial branch, the Departments of State Police, Corrections, Health and
Human Services, and Treasury, and the Legislative Retirement System. There is not a practical
way to determine the number of violations that will occur under provisions of the bill, so there
is not a way to estimate the amount of additional revenue that would be collected. The fiscal
impact on local court systems would depend on how provisions of the bill affected court
caseloads and related administrative costs. It is difficult to project the actual fiscal impact to
courts due to variables such as law enforcement practices, prosecutorial practices, judicial
discretion, case types, and complexity of cases.
POSITIONS:
The Mackinac Island Convention and Visitors Bureau indicated support for the bill. (5-14-24)
