Buses serve the public, perhaps on behalf of the world of human.
The red pickup truck, I think represents the precious blood of Jesus Christ.
A speeding pickup truck represents the approach of heaven.
A country road represents a song, country road, take me home,
The hat tilted as the car passed, a sign of respect.
The bus stands still, which means the world is always in the same place, no progress.
The black and white squares on the bus represent good and evil.
Fire represents a trial, or the fire of the Holy Spirit, or Lake of fire.
