Which item is a valid source to support a claim estimate?

• A. Social media posts about a vehicle.
• B. Weather forecasts for the accident day.
• C. Personal emails about the claim.
• D. OEM service bulletins.

Answer: (D)

When estimating a repair, use sources that establish official repair requirements and methods. OEM service bulletins provide the manufacturer’s approved repair procedures, required parts, torque specs, and recommended sequences. This information directly shapes what work is necessary and how long it should take, which in turn determines accurate labor and parts costs. Because they come from the vehicle maker, these bulletins reflect factory standards and any updates that affect repairs, making them the most reliable basis for a claim estimate.

Social media posts about a vehicle are not verified and can be inaccurate. Personal emails about the claim aren’t official or authoritative for repair guidance. Weather forecasts might influence claims logistics or events but don’t offer the repair procedures or cost implications needed for an accurate estimate.
