If you operate your own driving school, then you need to look for an insurance broker which specialises in fleet insurance. You do not want just a policy which will protect you in case the learner who is under instruction damages your vehicle while driving or performing manoeuvres also but want a
driving school insurance policy which has also liability coverage if there's accident involving another driver.
As there are more instructors these days, you will see that there are many insurers catering to this market and therefore
driving tuition insurance has become really competitive. Your best bet is to go to a specialist insurance broker for the cheapest and best deals available on the market.
