Our friend was injured when he crossed the road without looking properly.
He wasn't wearing his hearing aids so didn't hear the car coming.
A lot of our friends seem to be distracted by their phones, or are listening to music, when they are walking along the pavement.
So we've designed a poster encouraging people to put away the distractions and concentrate on what is going on around them.
Hopefully it will make things safer for us all.
The following people helped me with this fix:
Thank you to the Road Safety Trust for funding this campaign.
Me and my friends want young people to know that calories aren't the enemy!
