Which symbol on a business auto policy automatically provides coverage for injuries caused by a hit-and-run driver?

The correct choice is C, which is Symbol 6 - Owned Autos Subject to a Compulsory Uninsured Motorists Law. This symbol specifically extends coverage for injuries caused by an uninsured motorist, which includes situations involving hit-and-run drivers. In many states, when a hit-and-run driver is at fault and leaves the scene, the injured party can claim coverage under the uninsured motorist provisions of their policy.

Symbol 6 is particularly pertinent in this context because it reflects those vehicles that are defined under laws requiring uninsured motorist protection. This coverage is critical because it ensures that an insured party has recourse for injuries even when the at-fault driver cannot be identified or is uninsured, thereby protecting the insured from potential financial loss.

Other symbols, while relevant to different types of vehicles and situations, do not specifically cover incidents involving hit-and-run drivers in the same way that Symbol 6 does. For example, Symbol 1 provides coverage for any auto but does not specifically signify coverage for uninsured motorists under compulsory laws. Therefore, the unique characteristics of Symbol 6 make it the correct answer regarding coverage for injuries resulting from hit-and-run incidents.
