Sustrans are asking young people to design a postcard on how 20 mph could improve their street – it could be a picture, a message, a poem or even a slogan. Can you be a two-zero hero and tell us how slower speed limits might change your life? Get creative and win a holiday, bike or even a BMX stunt display!
