Let's use the aftermath of a major storm to illustrate the differences between collision and comprehensive. Within that storm, let's consider two hypothetical events: First, a heavy telephone pole was blown down and fell on your truck, or second, you swerved to avoid a falling tree and wound up crashing into a guardrail. In the first event, you couldn't control when or why a tree fell on your car. This kind of accident would get reimbursed under your comprehensive policy. In the second situation, you were driving the car and ultimately swerved into the guardrail. This makes it a collision, and collision insurance pays for the damages.
Drive Other Car insurance is similar to an Individual Named Insured Endorsement. If you need to borrow, test drive, rent, or lease a vehicle, Drive Other Car insurance will extend the coverages you’ve purchased for your commercial auto insurance policy - like Liability insurance, Physical Damage insurance, Medical Payments, and Uninsured Motorist Insurance, to a non-owned car.
