Is it illegal to drive with a cracked windshield in Michigan?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
It can be. Michigan’s vehicle code, MCL 257.709, prohibits driving with anything that obstructs the driver’s vision, and it names no crack size. The Michigan State Police say a cracked windshield can also fall under the defective-equipment statute, MCL 257.683, and draw a civil infraction. Whether a particular crack counts depends on how it affects your view.
What Michigan law actually says
Michigan’s vehicle code takes aim at obstruction rather than at cracks themselves. MCL 257.709, section 1(c), prohibits driving with anything that obstructs the driver’s vision, and a fracture that crosses your sightline is exactly the kind of condition that provision was written for. The statute sets no measurement — no line in it says a crack of a given length is lawful or unlawful.
Enforcement runs through a second statute. The Michigan State Police advise that a cracked windshield can fall under the defective-equipment statute, MCL 257.683, and draw a civil infraction. In practice that means the condition of the glass, not the mere existence of a crack, is what an officer weighs at the window.
The same section of the vehicle code also requires every windshield wiper to be kept in good working order, which matters here because a crack that catches a wiper blade — or a smear left by worn rubber — compounds the vision problem. See our Michigan wiper law answer for that side of the statute.
No crack size appears anywhere in the statute
Because MCL 257.709 names no dimensions, the judgment call belongs to the officer on the scene. A short chip outside your direct view rarely draws a second look; a long fracture sweeping across the driver’s side is a different matter.

When a cracked windshield draws attention in Michigan
The pattern behind most citations is the same: damage where the driver needs to see.
- A crack that crosses the driver’s direct line of sight through the glass.
- Long fractures that spread across the wiper sweep or reach the edge of the pane.
- Damage that distorts the view, such as a spreading star or a bullseye directly ahead of the steering wheel.
- Glass held together with tape or plastic film, which counts as an obstruction on its own.
- Cracks that have begun to branch outward, since they worsen visibly from week to week.

More questions about cracked windshields in Michigan
Can you get pulled over for a cracked windshield in Michigan?
Yes. Obstructed vision is grounds for a stop on its own, and the defective-equipment statute gives an officer a second basis for a civil infraction. A crack outside your view is far less likely to prompt a stop than damage squarely in your sightline.
How big of a crack is illegal in Michigan?
The statute does not draw a line at any length. What matters is whether the fracture obstructs your view of the road, so a short chip in a corner and a long crack across your side of the glass sit in very different positions.
What should I do while I wait for a replacement?
Cover a fresh chip with clear tape, keep the glass clean, and skip car washes and door slams, which push a fracture along. Chips up to about quarter size and cracks up to about six inches are usually repairable, so an early repair can settle the matter without a full replacement.
