Two states, one page. Neither has a glass-specific statute that changes the deductible math or the shop-conduct rules that other Midwest states have added. We track both here so we don't invent a distinction where none exists. If a rule changes, the statute wins and we'll re-check on our next scheduled pass.
Missouri and Indiana share a common feature that keeps this page short: neither has a windshield-specific law. Comprehensive coverage is optional in both states, so the first question is whether you carry it. If you do, a cracked windshield is a comprehensive claim, deductible comes off first, and the arithmetic is exactly the same as any other no-rule state. Our calculator handles both cases.
Missouri's auto-insurance chapter (Mo. Rev. Stat. ch. 379) covers rate filings and unfair practices in general terms, and there is no windshield-specific rule that waives a deductible, blocks a surcharge for a comprehensive claim, or requires ADAS calibration disclosure. Whether filing a glass claim raises your renewal is between you and your specific carrier's filed rating rule; our rate-impact guide covers what is actually knowable there.
Shop choice in Missouri is governed by general insurance-practice rules (an insurer cannot condition payment on a specific facility beyond what is reasonable), not by a glass-specific statute. If you get a hard steer to a network shop, you can politely say you've picked one and file anyway.
Indiana has a body-parts choice and notice statute (Ind. Code § 27-4-1.5-8) that governs collision-repair parts, but it is not a glass-specific rule. There is no Indiana law waiving your glass deductible, blocking a surcharge for a comprehensive claim, or requiring ADAS calibration disclosure. The rate-impact question is again between you and your carrier.
Shop choice in Indiana follows the same pattern as Missouri: no glass-specific right, but general insurance-practice rules protect against being forced to a facility that costs you more or requires unreasonable travel.
Because neither state has a glass-specific rule, the answer is arithmetic:
A 2021 Toyota RAV4 in St. Louis or Indianapolis. Windshield with a camera behind the mirror. Live pricing puts a real bookable quote around $340 for the glass and roughly $310 for the camera re-aim, so the honest total is close to $650. With a $500 deductible, insurance is ahead by about $150 (worth filing, small). With a $1,000 deductible, insurance pays nothing and cash is the clear choice.
The moment either state passes a distinctive rule: a glass-specific anti-steering statute, an ADAS calibration disclosure requirement, an assignment-of-benefits restriction, or a comprehensive-claim surcharge shield. Until then, one honest page beats two thin ones.
The calculator prices your specific car from your ZIP and shows the arithmetic for both paths, deductible included.
