Just wanting to check - I was on the receiving end of a shunt on the last lap of a race yesterday which knocked me in to the pit lane entry, I rejoined and crossed the finish line properly but presumably I could have continued along the pit lane and still have been credited with a finish - although if I broke the pit lane speed limit in doing so, I would presumably have been disqualified?

Yes, if you finish the race in the pitlane you're credited for the race, provided you don't speed and provided you're not serving a drive-thru.

As I thought, thanks
