If you work in trades associated with cars or the automotive industry there will likely be times when you will need to drive cars that don't belong to you. For example moving new stock around in a car dealership or test driving a customers vehicle after you have carried out some service or maintenance on it.
Driving cars in this manner for business purposes clearly cannot be allowed under a normal private motor insurance policy, however it would be impractical if not impossible to add named vehicles onto any type of policy in the course of your normal days work.
For this reason a special class of commercial motor insurance exists...
