: That wouldn't work, because the concession allowing the policy holder to : drive a borrowed car, makes it quite clear that it only applies to : occasional use.
Not on any of the policies I have at the moment, it doesn't.
For example:
1) Swinton policy on Volvo 240
Policy: Cover provided for you ... The same cover will apply if you are driving in the United Kingdom any car which the certificate of motor insurance allows you to drive provided you have the owner's permission to drive
Certificate: The policyholder may also drive any motor car not belonging to him (her) and not hired to him (her) under a nire purchase agreement.
Schedule: no reference
2) RH Brooklands Policy on Citroen DS
Policy: Driving Other vehicles. We will also provide the cover shown above (if this is specified in your certificate of motor insurance) to drive any private motor car that you do not own and have not hired under a hire purchase or leasing agreement, as long as you have the owner's permission to drive the car. You are not insured against the following * Any loss or damage to the vehicle you are driving * And event which ocurs outside the United Kingdom * Any event which occurs when the insurance is not in the name of an individual prson * Any liability if you no longer have possession of the insured vehicle
Certificate: The policyholder may also drive a private motor car not belonging to him/her and not hired to him/her under a hire purchase or leasing agreement, as long as the policyholder has the owner's permission to drive the car
Schedule: no reference
So, nothing about "occasional use", nothing about who the "main driver" is, nothing about the other car "being insured".
