Which of the following can be classified as "your covered auto"?

The classification of "your covered auto" is crucial in understanding personal auto insurance policies. A newly acquired auto or a trailer owned by the insured is covered under most standard auto insurance policies without requiring a specific endorsement or additional coverage. This provision recognizes that individuals often acquire new vehicles, and it provides continuity of coverage for them as soon as they are obtained.

Including newly acquired vehicles ensures that policyholders are not left without insurance during a potentially vulnerable transition period. Furthermore, trailers that the insured owns are typically included in this definition, thus offering protection for various types of vehicles associated with the policyholder.

While rented vehicles, borrowed vehicles, and those owned by family members might have some level of coverage under specific circumstances, they typically do not fall under the automatic coverage extended to newly acquired vehicles or trailers. Each of these categories may have specific requirements for coverage to apply, such as needing to add the vehicle to the policy or meet certain conditions. Hence, option B stands out as the correct definition of "your covered auto."
