I fully take onboard your comments re your
insurance companies t&c's and your point re a company policy is very valid.
Company policies tend to be ' blanket ' policies and there is a reasonable expectation as your transport manager demonstrated that an individual in the company is competant normally a CPC holder in understanding the T&C's of your
insurance.
FWIW, I assure you had you had an accident in the affected vehicle the third party claim would have been dealt with,However they could have excercised subrogation rights against your company also your companies own losses were exposed.
Legally there is far more protection provided to an individual than a company.
In simple terms, a Transport Manager or Company secretary is more aware of implications than the indiividual.
