More than 500 students witnessed a simulated fatal car crash in the grounds of Belfast City Hall.
The live demonstration was part of the Roadsafe Roadshow aimed at teenagers, to try and reduce the number of collisions here.
So far in 2017 there have been 48 fatalities on our roads.
Some teenagers were left in tears after watching a hard-hitting video of a young crash victim.
To push the message home, paramedics, police and firefighters joined actors to re-enact the aftermath of a fatal road collision.
Rory Dumigan from NI Fire and Rescue Service and one of the Roadshow leaders lost his sister in a crash in 2004. She was just 18.
He said: "If one young person comes away from it thinking that it's going to change their attitude to driving, then it's worth it."
