"If you kids want to make some friends here in the city, you have a lot to learn about civilization," said Elizabeth.
As they got closer to downtown, they began to go past buildings that took up entire blocks, but weren't more than two or three stories tall since they were further away from downtown than the taller buildings. Pedestrians (practically all of them Rainbowfaces) on the sidewalk were starting to become frequent. The bus stopped at another 4-way intersection, but there was no stop sign. Instead, there was a traffic light, and the red light was currently on.
"Why did we stop?" asked Littlefoot. "I don't see a 'stop sign' here."
"You see, some intersections are so busy that a stop sign isn't enough," replied Steven. "Instead, traffic lights are used. A green light means we're allowed to go, a yellow light means we have to slow down, and a red light means that we have to stop. As you can see, we currently have a red light. when it turns green, then we can go."
The light then turned green. The bus began to move forward, but one car sped through the intersection when he had a red light, forcing the bus and a car in the opposite lane to immediately stop to avoid a collision. Fortunately, the speeder didn't hit anything. The driver of the car in the opposite lane honked the horn, shook his fist out the window and shouted, "Get off the road, jerk!"
"And sometimes there will be some dumb-ass who decides to run a red light," said the bus driver, before continuing through the intersection.
