Michigan House Bill 6273 amends the state vehicle code to update rules regarding speed limits in school zones. The bill allows county road commissions to permanently lower a school zone speed limit to 25 miles per hour upon request from a school district, without requiring a new traffic study. It also clarifies that temporary reduced speed limits can be set up to 30 minutes before and after school sessions, with flexibility for superintendents to adjust these times based on specific schedules or off-campus lunch periods.
This bill amends the Michigan Vehicle Code to increase penalties for traffic violations occurring in work zones, school zones, and school bus zones. It mandates that fines for moving violations in these areas be doubled and elevates offenses causing injury or death to misdemeanors or felonies, respectively. Additionally, the legislation adjusts sentencing guidelines for fleeing and eluding police, making penalties more severe based on factors like prior convictions and the severity of the outcome. The changes also clarify definitions for emergency scenes and school bus zones to ensure consistent application of these stricter rules.
This bill modifies Michigan's vehicle code to update rules for speed limits and enforcement in school zones. It clarifies definitions for school zones and adjusts the timing of when lower speed limits must be enforced, expanding the window before and after school sessions to 60 minutes instead of 30. The legislation also allows school superintendents to set additional enforcement periods for times like off-campus lunch and field trips, while maintaining a minimum speed limit of 25 mph in these zones. Additionally, it permits the use of digital signs and flashing lights to display school zone speed limits and requires specific signage for year-round schools.
This bill amends Michigan's vehicle code to require drivers to pass county road worker vehicles with the same caution and speed restrictions as they must when passing stationary emergency vehicles. It defines road work vehicles as those used for construction, maintenance, or utility work displaying flashing red or amber lights, and updates the legal definitions of authorized emergency vehicles to include these road service vehicles. Drivers must reduce their speed by at least 10 miles per hour and move at least one lane or two vehicle widths away from the stationary vehicle when possible, with penalties including civil fines for violations. The changes apply to all public roadways and align the treatment of road workers with that of police, firefighters, and other emergency responders.
HB 5533 modifies Michigan's school zone speed limit rules. It defines a "school zone" as property within 1,000 feet of a school building and sets a reduced speed limit (minimum 25 mph) that applies up to 30 minutes before school starts and until 30 minutes after school ends, rounded to the nearest 5 minutes. School superintendents can adjust these timing windows for off-campus lunch or different school hours. The bill also requires "All Year School" signs for year-round schools and mandates that all signage follow Michigan's traffic control device standards. This directly affects drivers near schools and school officials managing zone timing.
HB 5523 requires Michigan auto insurers to offer a premium discount to drivers aged 50 and older who complete a state-approved traffic safety course. Insurers must provide a 3-year discount after successful completion of either an 8-hour initial course or a 4-hour refresher course. The courses must cover aging effects on driving, road signs, medication impacts, safe driving practices, and crash prevention, taught by certified instructors. Upon completion, participants receive a certificate to apply for the discount.
SB 580 modifies Michigan's rules for issuing restricted driver's licenses to individuals suspended due to DUI convictions. It requires installing an ignition interlock device and completing a specialty court program before eligibility, limiting driving to work, treatment, school, or essential appointments. The restricted license remains valid for at least one year, during which any alcohol use could trigger further suspension. This applies to those with two DUI convictions or one DUI plus prior related offenses under Michigan law.
HB 4391 expands Michigan's vehicle code to allow law enforcement to test for intoxication using other bodily fluids beyond blood or breath, such as urine or saliva. It directly affects drivers suspected of operating a vehicle while impaired, updating sections 625a, 625c, and 625g of the 1949 Michigan Vehicle Code (MCL 257.625a et seq.). The bill amends existing testing methods to include these additional fluids, providing more flexibility for officers during DUI investigations. The bill passed the Michigan House on July 17, 2025, with immediate effect.
House Bill 4334 proposes to enhance penalties for drivers who commit moving violations that result in physical injury or death to vulnerable roadway users. The bill amends several sections of the Michigan Vehicle Code (1949 PA 300) and adds new sections to implement these stricter consequences. Its aim is to increase accountability for drivers whose actions lead to harm for pedestrians, bicyclists, or other vulnerable individuals on the road.
HB 4137 updates Michigan’s speed limit rules to require local governments to set limits based on actual traffic speeds and safety data. It mandates that speed limits be determined using traffic engineering practices, rounded to the nearest 5 mph, and generally align with the 85th percentile speed of free-flowing traffic on a road segment. Exceptions allow lower limits (down to the 50th percentile) only when safety hazards are proven through engineering studies. This directly affects county road commissions, township boards, and city officials responsible for setting speed limits on local roads and highways.
