It depends on the specific circumstances of the arrangement between you and your company, and the laws and regulations in your jurisdiction. In general, if your company owns the vehicle and requires you to use it for business purposes, it is responsible for providing and maintaining insurance coverage for the vehicle. However, if you own the vehicle and use it for business purposes, you are generally responsible for obtaining and maintaining your own insurance coverage.
It's important to clarify the insurance responsibilities and arrangements with your company to ensure that you have adequate coverage when using a vehicle for business purposes. If you are using your own vehicle for business purposes, you may need to purchase a commercial auto insurance policy or a business use endorsement on your personal auto insurance policy to cover any potential risks or liabilities that may arise during business use.
