A corporate fleet vehicle is any vehicle owned by a company. Most are part of a sizeable fleet of vehicles that are normally used for conducting company business. Most companies have their vehicles covered by some sort of fleet maintenance contract. These contracts can be through dealerships, maintenance programs and commercial insurance providers. Having your corporate fleet maintenance carried by a commercial auto insurance provider allows you to pay for both services with your payment. With a service contract through a dealership or the car maker, you will be more likely to receive reminders when recommended service intervals have been reached or are approaching.
