Impeding traffic in Michigan is not one law but several overlapping civil infractions: physically obstructing a roadway, staying in the left lane on a multi-lane highway when you’re not passing, and driving below a posted minimum speed limit. Each carries a fine of up to $100 plus court costs, two points on your driving record, and insurance consequences that usually outrun the ticket itself.
The Three Violations That Get Called Impeding Traffic
The phrase covers different conduct depending on which statute the officer cites. Knowing which one applies to your situation matters, because the defenses and the facts an officer has to prove are different for each.
Physical Obstruction of a Roadway
MCL 257.676b prohibits interfering with normal traffic by placing a barricade, object, or device on a public road, or by standing in the roadway without authority. This is the statute behind tickets for blocking a lane during a protest, dragging debris onto a highway, or standing in an intersection without authorization. The law carves out narrow exceptions for public utility crews working on or near the roadway and for certain charitable solicitors who meet strict insurance and safety requirements. 1Michigan Legislature. MCL – Section 257.676b A violation is a civil infraction, the same classification as a standard traffic ticket.
Driving Below a Posted Minimum
Michigan authorizes state and local agencies to set both maximum and minimum speed limits based on engineering and traffic studies. Where a minimum is posted, driving below it without justification is a civil infraction under MCL 257.628. 2Michigan Legislature. Michigan Compiled Laws Section 257.628 – Maximum or Minimum Speed Limits Freeways and major highways commonly have posted minimums, and that’s where most slow-driving tickets originate. Roads without a posted minimum don’t trigger this statute.
The Keep-Right Rule
On any roadway with two or more lanes traveling in the same direction, drivers must use the extreme right-hand lane unless they are passing, turning left, or directed otherwise by signs or an officer. 3Michigan Legislature. MCL – Section 257.634 The law does not require you to speed up for faster drivers behind you. It requires you to move right when you’re not actively passing. Cruising in the left lane at or above the posted limit while traffic stacks up behind you is exactly the conduct this statute targets, and it catches drivers off guard more than any other version of impeding.
What the Ticket Will Cost
The base civil fine for a standard impeding violation under the Michigan Vehicle Code is capped at $100. 4Michigan Courts. Civil Infraction Fines, Costs, and Assessments Table Court costs and state assessments are added on top, so the total bill usually lands in the low-to-mid hundreds. The exact figure depends on the court and jurisdiction.
If the impeding violation contributed to an at-fault collision, the fine for the underlying moving violation is increased by $25, though it still cannot exceed $100. 4Michigan Courts. Civil Infraction Fines, Costs, and Assessments Table The bigger financial consequence of an at-fault crash tied to impeding comes from your insurer, not the court.
Points on Your Driving Record
Michigan assigns two points for most moving violations that don’t have a specific higher point value, and impeding traffic falls into that general category. If the violation causes an at-fault collision, it carries four points. Points stay on your record for two years from the date of conviction. 5Michigan Secretary of State. Chapter Two – Your Driving Record
Two points from a single ticket won’t do much on its own. The problem is accumulation. Once you reach 12 or more points within a two-year window, the Secretary of State schedules a mandatory reexamination of your driving ability. 5Michigan Secretary of State. Chapter Two – Your Driving Record
A reexamination is not a formality. A driver analyst reviews your record and discusses your driving behavior with you, and the Secretary of State can then restrict your license, suspend it for up to one year, revoke it, or combine those actions. 6Michigan Legislature. MCL – Section 257.320 You have the right to appeal any resulting licensing action. 5Michigan Secretary of State. Chapter Two – Your Driving Record Failing to appear at the reexamination triggers an immediate suspension that remains in place until you show up.
The Insurance Hit
Insurance companies pull your driving record when setting premiums, and points from an impeding conviction will appear. A single minor moving violation can raise your annual premium noticeably, and the increase tends to last for the two years the points remain. Multiple infractions in a short window compound the effect and may lead an insurer to reclassify you as high-risk or decline renewal.
The gap between the ticket and the insurance fallout is where most drivers underestimate the real cost. Fine plus costs is a one-time payment in the low hundreds. Higher premiums over two or three years can total significantly more.
Defenses If You Were Ticketed
The most direct defense is that conditions justified the reduced speed. Snow, ice, heavy rain, and fog all create situations where driving well below the posted limit is the only safe option, and Michigan law accounts for that. The distinction between a cautious driver in a whiteout and someone doing 35 on a clear, dry freeway matters in court.
Mechanical problems are another recognized justification. A car losing power, overheating, or having brake trouble may force a driver to slow dramatically or pull partly into a lane. The key is showing the situation was genuinely beyond your control and that you took reasonable steps to minimize disruption, such as activating hazard lights or pulling off as soon as safely possible.
Michigan’s impeding laws don’t set a specific speed below which you are automatically in violation, so every stop involves an officer’s judgment call about whether your speed was unreasonably slow for the conditions. That judgment can be challenged. Dashcam footage is increasingly useful, since video of traffic conditions, your speed, the weather, and the officer’s approach can directly counter a subjective assessment. If you plan to rely on dashcam evidence, keep the original file unedited and be ready to explain how it was recorded and stored, since courts require the video to be authentic.
For a charge specifically under MCL 257.676b, the statute itself contains built-in exceptions for public utility workers maintaining facilities near a roadway and for qualifying charitable solicitors. 1Michigan Legislature. MCL – Section 257.676b
Extra Steps for CDL Holders
A commercial driver’s license adds obligations after any traffic conviction. Federal regulations require CDL holders to notify their employer in writing within 30 days of being convicted of any motor vehicle traffic violation other than a parking ticket. The written notice must include your full name, license number, date of conviction, the specific violation, whether it occurred in a commercial vehicle, and where it happened. 7Michigan Secretary of State. Michigan CDL Manual – Section 1 Introduction
Impeding traffic is not specifically listed among the federal “serious traffic violations” that trigger CDL disqualification. Those include excessive speeding, reckless driving, improper lane changes, and following too closely. 8eCFR. 49 CFR 383.51 – Disqualification of Drivers If the underlying conduct that led to an impeding charge also involved an improper lane change or reckless behavior, the classification could be different. And regardless, the conviction still appears on your record and still has to be reported to your employer. For a driver whose income depends on a clean CDL, contesting even a minor moving violation can be worth the effort when the facts support a defense.
