Is it illegal to drive with snow or ice on your windshield?

Quick answer
It can be. The same obstructed-view laws that apply to a cracked windshield apply to snow and ice in all three states — Michigan, Indiana and Illinois each bar driving with anything that obstructs or materially impairs the driver’s view. Clearing all the glass before you drive is the straightforward way to stay on the right side of the law.
Snow and ice are obstructions under the same statutes
The vision statutes in all three states are written broadly. Michigan’s MCL 257.709 bars anything that obstructs the driver’s vision; Indiana’s Code 9-19-19 bars anything that obstructs the clear view of the highway; Illinois’s 625 ILCS 5/12-503(e) bars defective condition that materially impairs the view. Snow and ice fall squarely inside each of them.
A peephole cleared in the frost is the classic violation — a small opening in an otherwise opaque windshield. The statute does not require the whole pane to be clear before it applies; it requires the driver’s view not to be obstructed, and a frosted-over windshield fails that by definition.
The practical answer is the same in every state: clear all the glass, not just a viewing hole, before you move the vehicle. Our snow removal guide walks through doing it without scratching the glass or cracking a cold pane.
The obstruction standard is the same one that applies to a cracked windshield, which means the officer’s judgment works the same way. A thin frost the wipers clear in a stroke is different from a pane still white with ice when you pull onto the road, and the difference between the two is what the statute turns on. Clearing the whole pane, not just a viewing hole, is what keeps the drive legal in all three states.
A peephole is not a cleared windshield
Driving with a small cleared patch in an iced-over windshield is the clearest way to be cited under the obstruction statutes. Clear the whole pane. This is a plain-language summary of three state laws, not legal advice.
Clearing the glass properly before you drive
A few minutes of preparation keeps the view legal and the glass intact.
- 1
Start the vehicle and warm the defroster
Let the defroster begin softening the ice while you brush the loose snow off the roof, hood, and glass.
- 2
Brush, then scrape
Brush snow away first, then scrape ice with a plastic tool. Never pour hot water on cold glass — the thermal shock can crack it.
- 3
Clear every pane
Do the windshield, the side windows, the mirrors, and the back glass. A clear windshield with frosted side windows still leaves blind spots.
- 4
Check the wipers last
Free the blades from the glass before switching them on, and confirm the washer fluid sprays before you need it on the road.
More questions about snow, ice, and the law
Can you get a ticket for not clearing your windshield?
Yes. Snow and ice that obstruct your view fall under the same obstruction statutes as a cracked windshield in Michigan, Indiana and Illinois.
Is it illegal to drive with a frosted windshield?
When the frost obstructs or materially impairs your view, yes. A peephole cleared in the frost does not meet the standard in any of the three states.
Do I have to clear snow off my car?
Clear the glass you drive through — the windshield, side windows, mirrors, and back glass. Snow left on the roof can also slide onto the glass once you are moving, so brushing it off is the safer habit.
