Yes, and as a word of caution declare overseas accidents too. My mates dad had a bump while working in Venezuela in a hire car and didn't declare it to his UK insurance provider. The family motor (a very tired Mondeo estate) was stolen and after a lot of wrangling, hassle & problems the insurance company refused to pay out. They also threatened to void his policy if he pursued the claim in court which would have buggered his insurance for life. Spill it out...
