You should be covered if you are using your employer's car during the course of your employment and within the scope of your duties. For example, if you are a delivery driver and you are using your employer's van to make deliveries, you would likely be covered by your employer's insurance.
However, if you are using your employer's car for personal reasons, such as commuting to work or running errands, you may not be covered by your employer's insurance. In this case, you would need to have your own insurance policy that covers you for driving your employer's car.
You should check with your insurance company to confirm whether or not your policy covers you for driving your employer's car. You should also check with your employer to find out what insurance coverage they have and what the terms and conditions of their policy are.
