Parents whose children are starting secondary school are being urged to speak to them about road safety.
Mike Ashworth, of the Derby and Derbyshire Road Safety Partnership, said: “Children learn about road safety at primary school but once they get to secondary school they are more likely to be faced with distractions.
“In our area, the number of weekday road injuries among 11 and 12 year old pedestrians is more than two-thirds greater than the number among nine and 10 year olds.
“Explain to your children that safety should be their number one priority when crossing the road. Warn them that they will put themselves at risk if they listen to music, use their mobile or chat to their mates while crossing the road.”
