So, imagine you are playing with your toy cars and you have many of them. Now, imagine you line them up and push one into another, which then hits the car in front of it, and so on until they all crash into each other. This is kind of what happens in a multiple-vehicle collision.
In real life, cars are much bigger and faster than toys, and when they crash into each other, it can be very dangerous. A multiple-vehicle collision happens when three or more cars crash into each other in the same accident. It's like a big car pile-up.
How does this happen? Well, there can be many reasons why a multiple-vehicle collision occurs. Sometimes, it's because one car crashes into another one and causes a chain reaction. Sometimes, it's because there is bad weather, like fog or rain, that makes it hard for drivers to see or control their cars. Sometimes, it's because there are a lot of cars on the road, and they all get too close to each other.
When a multiple-vehicle collision happens, it can be very scary and dangerous. Cars can flip over or get smashed, and people inside can get hurt. That's why it's important to always wear your seatbelt and keep your eyes on the road when you're driving. If you see a multiple-vehicle collision happening, it's important to stay calm and call for help right away, so that people can get the medical attention they need and the cars can be cleared from the road.
