If you drive for Uber or some sort of delivery company, food firm or even a pizza shop delivering pizza. Please, please, please for the love of God....tell your insurer.
Using your vehicle for commercial uses is a policy violation in most cases unless you have already declared that as a use. Then you will have to meet someone like me who makes you sign forms (yuck!), take a recorded statement and all sorts of other nasty stuff.
Don’t meet me. Insure your car properly.
