Louisiana Glass Bill Advances Through House, Senate Vote Awaited

The first week of April 2026 carried legislative news from Louisiana, where HB 929 — the Louisiana Motor Vehicle Glass Law — had cleared third reading in the state House by March 30 and was positioned for Senate consideration. The bill was closely modeled on the NCOIL framework that had already produced laws in Iowa, Kentucky and, more recently, Virginia.

As written, the Louisiana bill would require auto-glass shops to obtain a claim number from a customer's insurer before officially entering into a service agreement. It also included ADAS notification requirements consistent with the NCOIL template: shops would need to inform customers whether their vehicle's driver-assistance systems required recalibration after a windshield replacement and whether the shop intended to perform or was capable of performing that recalibration.

The glass industry's response in Louisiana was more divided than in some other states. Some shop owners supported disclosure requirements for ADAS — arguing that customers deserved to know when their safety systems needed recalibration — while others viewed the claim-number provision as giving insurers and TPAs a chokehold over shop operations, since a claim number could theoretically be withheld or delayed, preventing a shop from starting legitimate work.

Louisiana shops and other interested parties still had an opportunity to contact their state House representatives before the bill came up for a floor vote, since the schedule for Senate debate had not yet been confirmed. That window for influence was a recurring theme in the 2026 legislative cycle: shops that waited for certainty before engaging often found the process had moved past the point where testimony could shape outcomes.

For shops in states watching Louisiana's bill as a precedent, the key variables were whether the claim-number requirement survived the Senate or was stripped as it had been in Virginia, and whether the governor would sign the bill if it passed.
