Which of the following tasks does an appraiser perform?

An appraiser plays a critical role in the automotive damage assessment process primarily by inspecting damage and calculating the worth of a vehicle. Through a detailed inspection, an appraiser evaluates the extent of the damage, considering factors like the vehicle's make, model, age, mileage, and market conditions. This comprehensive analysis allows the appraiser to determine a fair and accurate valuation of the vehicle, which is vital for insurance claims, resale, or repair estimates.

The other tasks mentioned are outside the typical scope of an appraiser's responsibilities. Managing warranty claims involves administrative functions related to product guarantees rather than evaluating vehicle damage. Conducting driving tests pertains to assessing vehicle performance and safety, which is not an appraiser's function. Issuing insurance policies is a task assigned to insurance agents or companies, rather than appraisers focused on damage assessment. Thus, the primary responsibility of an appraiser is the inspection and valuation of automotive damage.
