Insurance while trailering your bike.

So, do you tell your bike insurer you are towing it on a trailer or the car insurance or both?

I don't my beloved to get side swiped lby some numpty and then can't replace it cos it ain't covered!

Very good question mate,i'm not sure either so i'll watch this space with interest. I've always assumed that the towing vehicle's insurance would cover it,but who knows in this day and age i bet they have a get out clause.
