Virginia has no statewide law on loaded rifles in a vehicle. It's usually regulated with the hunting laws by localities.
California (where Zeroturbulence lives) prohibits loaded firearms in vehicles (other than handguns for those few with a CCW). You can't even have an unmarried handgun and loaded magazine in the passenger compartment unless one of the two is in a locked case.
Colorado (where I live) permits loaded rifles as long as they are visible
