the Hagerty website states you can drive your car on a limited basis- e.g. club functions, exhibitions, organized meets, tours and limited pleasure driving ( no mention of work ).
It also states that collector vehicles must be stored in an enclosed, secure structure when not in use.
Obviously you also can not park it in your driveway overnight at your house or cottage. It is worth calling your agent to find out what you can and can not do.

I agree, when I had Hagerty insurance, they told me the same thing. I couldn't drive my A to work, couldn't drive my AA to the hardware store to pick up stuff and the cars had to be stored under lock and key when not in use. I had to send detailed pictures of the cars insured and the buildings that they would be stored in.
