It is revealed that the first episode of The Walking Dead season 4 is called “30 Days Without an Accident.”
I think it’s safe to assume that there’s going to be an unknown amount of time-skip between season 3 and season 4, and our main characters are building up a small community for themselves. However, I think it’s also safe to say that the community is not going to be accident free by the end of the episode.
Again, the season will return in October. That’s not too far from now.
