Final answer:
Coverage for an employee injured while using a company vehicle for business purposes would generally be provided by workers' compensation insurance, as it is designed to cover work-related injuries and illnesses.
Step-by-step explanation:
When an employee is injured while using their employer's auto for business purposes, the coverage for the employee's injuries typically comes from workers' compensation insurance. This type of insurance obligates employers to pay into funds that provide benefits to workers who suffer job-related injuries, regardless of fault. It generally covers medical expenses, lost wages, and rehabilitation costs.
In the given scenario, bodily injury liability would not apply as it covers injuries that the insured's vehicle causes to third parties, not the insured's employees. Medical payment coverage can sometimes provide for minor medical expenses regardless of fault, but it is not the primary source of coverage for work-related injuries. Comprehensive payments pertain to damage to the vehicle itself due to causes other than collision (e.g., theft, hail, vandalism), and would not cover injuries.
