I have no definite answer. Maybe it was inspired by real-life incidents, or maybe it was made up from scratch. More context is needed to figure it out.
I don't think it is. Usually, such titles are made up to draw readers' interest and don't represent real events. Maybe there are some fictional elements inspired by real-life situations, but it's not a straightforward true account.
Definitely not. 'Wait in the Truck' is a work of fiction. It doesn't draw inspiration from any true story. The story was made up to entertain and engage the readers/viewers.
