Imagine you're playing with your toy cars, and you decide to crash one into another. That's kind of what a vehicle ramming attack is, except it's not a game and it's very dangerous and wrong.
It's when someone uses a big, heavy vehicle, like a car or truck, to intentionally crash it into people or things, like buildings or other cars. This can hurt or kill people and cause a lot of damage.
Sometimes, people do this on purpose because they want to hurt other people, like in a terrorist attack. Other times, it might be by accident, like if someone is driving and loses control of their vehicle.
But no matter why it happens, it's not okay. We can help prevent it from happening by being safe when we drive and making sure we don't hurt others on purpose.
