Under a commercial auto policy providing physical damage, which of the following offers the broadest coverage?

The comprehensive coverage under a commercial auto policy provides the broadest level of protection for physical damage to the vehicle. This type of coverage typically safeguards against a wide range of risks and incidents, including theft, vandalism, fire, natural disasters, and damages caused by hitting an animal or falling objects.

In contrast, specified cause of loss coverage is more limited, as it only covers specific events that are explicitly listed in the policy, such as fire, explosion, theft, or certain natural disasters. Named perils also restrict coverage to explicitly stated perils, which can vary from one policy to another, reducing the range of potential protections. Broad named perils expands on the named perils coverage but still does not encompass as wide a range of potential issues as comprehensive coverage does.

Therefore, comprehensive coverage is ideal for those seeking maximum protection for their vehicles, covering a myriad of potential risks that could lead to damage, making it the best choice for broad coverage under a commercial auto policy.
