1. Do not bring bottles or hard objects as they can cause accidents and hurt other participants.
2. Do not rip other people's T-shirts.
3. You must squash the tomatoes before throwing them as this reduces the impact.
4. Ensure you keep a safe distance from the lorries.
5. As soon as you hear the second shot, you must stop throwing tomatoes.

The authorities did try to dissolve it a few times but it finally became an official festival in 1957.7. The festival was initially free for participants from 1945 to 2012, but in 2013 the Mayor of Bunol imposed a 10 euro entry fee for non-residents.
