How can interactive campaigns reduce road accidents among young people?

I don’t usually post here, but this topic really made me think. Just the other day, my cousin told me how one of his classmates got into a motorbike accident — he was speeding, no helmet, filming for TikTok. Thankfully, he’s okay now, but it shook everyone. It’s like young people don’t take road safety seriously until something bad happens. I keep wondering — what actually works when it comes to getting through to them? Traditional warnings and signs just don’t stick anymore. Maybe something more engaging or interactive can help, but what would that even look like? Anyone seen something that really worked?
