There could be a dispatcher as one of the main characters. If the story is set in a more commercial trucking context, the dispatcher might be in communication with the driver of the runaway rig, trying to guide him or her through the crisis. Also, there could be a local law enforcement officer who attempts to stop the rig and keep the public safe, making them a main character in the story.
Since I don't know the story, it's hard to say. But it could be the driver of the rig. He would be a likely main character as the one in control (or trying to be in control) of the runaway rig.
Maybe there's a mechanic in the story. If the rig is running away due to some mechanical issue, the mechanic could be a main character. He might be the one who tries to figure out what's wrong with the rig while it's on the run. There could also be a bystander who gets involved in trying to stop the rig, and they could be a main character too.
I'm not sure specifically as I haven't read that particular 'runaway rig short story'. It could be about a runaway vehicle like a truck (a rig) that goes out of control and the events that unfold around it, such as the people trying to stop it or the chaos it causes on the road.
I'm not sure specifically as I don't have the details of this particular 'the runaway short story'. But often it could be a young person, like a teenager who is frustrated with their home life and decides to run away.
In the 'runaway kids story', the main characters are most probably the kids who run away. There could also be other characters like the people they meet during their journey, for example, a kind old lady who gives them shelter or a mean - spirited person who tries to take advantage of them.
A mother could be the main character in such a story. She runs away from her over - demanding family to have some time for herself, to rediscover who she is outside of her family roles. She goes on a solo journey and has a series of self - reflective experiences.
In the 'the runaway pizza online story', the main character is most likely the runaway pizza. However, there could be other important characters too. There might be a hacker who tries to use the runaway pizza for some devious plan. Or perhaps a young kid who accidentally ordered the pizza and now is on a quest to find it in the online world. There could also be an AI system that is tasked with tracking down the pizza to maintain order in the digital food delivery system.
In the 'the runaway bunny full story', the two central characters are a young bunny and his mother.

The runaway pancake is the central character in the story. Then there are the animals that the pancake encounters. For example, there could be a hungry hen that sees the pancake as a delicious treat.

The main character is, of course, the Runaway Kid. And then there are the various menacing creatures he encounters, like the Janitor.
Astrid could also be a main character. Maybe she runs away for some reason and her dragon Stormfly is with her. Or she could be chasing after Hiccup and Toothless if they are the ones on the run.

Since I don't know the specific 'runaway wife novel', I can't tell you the exact main characters. But typically, there would be the runaway wife herself.

And perhaps there are some friends or family members on either side who play important roles in the story.
