Quick answer
Start the claim early. Ask for the written notices.
Act 327 applies Louisiana unfair-insurance-trade-practice rules to specified motor-vehicle-glass conduct. For a qualifying first-party insurance job, the statute requires a claim or referral number and written notices concerning ADAS when the system is present.
The act became effective upon the governor's signature or the alternative dates stated in the enacted law. For an individual claim, the policy, insurer's confirmation, and vehicle manufacturer's published procedure still matter.
Claim setupFirst-party insurance work
The claim or referral number requirement
Before contracting for motor-vehicle-glass repair or replacement to be paid under a first-party insurance policy, Act 327 lists three qualifications: the person has made a first-party claim, the shop has received a claim or referral number, and the shop has provided the required written ADAS notification when the vehicle has an ADAS.
If you are filing through insurance
Begin the claim early and keep the claim or referral number with your repair records. A shop may assist you, but coverage and approval should be confirmed through the insurer or its agent.
If you are paying without insurance
The statute's first-party-claim contracting condition is written for work paid under a first-party insurance policy. Ask the shop to explain the payment and documentation process that applies to your situation.
Estimate and receipt
The act prohibits repair or replacement without first providing the insured a written, good faith estimate of anticipated fees and costs. It also calls for an itemized invoice and receipt upon payment.
Do not rely on assumptions
A shop may not say that an insurer approved work, or that the work will be entirely paid at no cost, without the verification described in the statute.
ADAS noticesWritten disclosure
What the shop must explain when ADAS is present
When a vehicle has an advanced driver assistance system, Act 327 requires a written notice addressing whether manufacturer-recommended calibration or recalibration is needed after the glass work, and whether the shop intends to perform it to manufacturer specifications.
Before the work
Ask for the written notice and confirm the exact vehicle configuration being discussed. The law refers to the vehicle manufacturer's recommendation; it does not create one universal answer for every windshield replacement.
If the shop will not perform it
The written notice must say the vehicle should be taken to a certified dealership or qualified specialist capable of performing the calibration or recalibration described in the act.
After calibration
When calibration or recalibration is performed, the statute requires written completion notice on whether it was successful according to manufacturer specifications and whether further specialist work is recommended if it was not.
Keep the records
Save the estimate, ADAS notices, final invoice, receipt, and any completion documentation with your vehicle records.
Driver checklist
Five questions to ask before the windshield work starts
- Have I made a first-party claim and received a claim or referral number, if I am using insurance?
- What written, good faith estimate will I receive?
- Does my vehicle have an ADAS, and what does the manufacturer's published procedure call for?
- Will the shop perform calibration or recalibration to manufacturer specifications, or refer me to a qualified specialist?
- What documentation will I receive after the work is complete?
