One of the things that you really need to consider is that you should get a dual control on things. This would mean that you should be able to actually get the things you need most: for example, you are able to let someone else to drive the car such as a student when it comes to teaching that person or to be able to drive so that the examiner would be able to get things to go your way.

A courtesy car cover would actually cover your need to get another car in case that you need it and your car breaks down along the way or something like that. In case your car accidentally leaves you hanging on a deserted road, this should be able to give you the car that you need to continue on with your lessons or prior engagements.
Another thing you ought to try out is commercial expenses coverage which should cover your needs to actually promote yourself as well as your school so that you are able to reach more people in the process.
