There are several instances of gun violence.
A woman wounds a man with a double-crossbow, sending a long dart right below the man's eye and through to the back of his head and another bolt into his chest with some blood flow; the wounded man jumps off a tall vehicle and slams two spears into another vehicle, which explodes and presumably kills him.
We briefly see a chainsaw cut into a man, with some blood spraying.
People get ran over by huge cars countless times throughout
A brutal brawl breaks out between three main characters, they are pistol whipped and tackled to the ground.
A war boy is pistol whipped in the face with blood spurts.
The violence is almost completely bloodless until the last 30 minutes, where blood and gore become much more frequent.
A man is shot from a far distance. We later see that both of his eyes got shot. Blood is all over his wounds.
Only 1 scene of R-rated violence towards the end, where Furiosa rips of Immortan Joe's face, and the scene is shot at a distance and not in the focus of the camera (easily skippable). The rest of the movie has mild blood and no gore
Though actual gore is kept to a minimum, there are frequent scenes of violence and very long vehicular chase scenes. These include scenes where people fight or are shot. However, injury detail is very limited.
Many people are shot but it cuts before the actual gore is seen. But sometimes it is seen.
