Apologies if this has been covered elsewhere - had a go on the search facility, but didn't immediately find anything.

I am heading abroad with work for about three years. I am unlikely to drive while I am over there, as a driver is provided. Before heading off, I plan to sell my car and cancel my car insurance. However, when I get back, I shall want to buy a car and start driving again. Anecdotally, I have heard that gaps in car insurance coverage can be problematic. Is there anything I can do to avoid problems when I seek to take up car insurance again in three years?

Thanks in advance for any guidance.
