This will be based on official government road death statistics.

May not resolve until the end of February as deaths within 30 days qualify. (I will only delay resolution if the numbers are very close together)

May not resolve to yes immediately upon the number exceeding the previous year's total as sometimes deaths are reclassified later (as certain types of deaths on the road aren't included in the official statistics). Again, if the numbers aren't close together, then it will resolve appropriately.

For the purposes of extending resolution time, 5 deaths difference will be considered "close together". Close date will remain midnight 31st December, though.
