Thanks for this so the question is, if it does require an extension to the policy (which most insurers would say it does) then will the disclaimer we wrote in our first note to you (see below) be enough if we tell the candidates that they need to be insured.
'You [the candidate] agree that you alone are responsible for ensuring you have adequate car insurance when driving yourself and colleagues to and from a shift and understand that [our company] is not responsible.'
sorry one last question, i forgot to mention that the candidates can get paid travel time, so time spent travelling to and sometimes from work. could that be misconstrude as the candidates 'working' when they are sat in the car and therefore the car being used for 'work purposes'? They can also get travel time if they get the train and sometimes the bus.
