Most parents go out of their way to teach road safety to children, but some risks are more obvious than others.
Campaigners have been sharing images showing just how much dark clothing can hide a child from view - and it's striking fear into families.
The two photos are exactly the same, apart from the clothing worn by the child. And in the one where the child is in dark clothes, they are barely visible.
Mini First Aid Manchester South shared the photos on its Facebook page, alongside a warning for children to wear bright colours.
The post , which has had a huge reaction - amassing more than 3,000 shares in less than a week - states: "It's hard to believe, but there is the same child on the picture two, wearing dark clothes. Zoom the picture to see it!
"Please make sure your kids are wearing bright colours to stay visible for drivers. Especially this time of the year with the early darkness and autumn weather."
Mum-of-three Danielle Wood is a trainer at Mini First Aid Manchester, which teaches families, including children, vital first aid skills.
She said: "The post highlights the importance of wearing brighter colours in the coming darker evenings and general road safety.
"It appeals to both parents and drivers. Many people cannot see the child in the second photo which they find really shocking. We’ve had driving instructors and nurseries share the post to highlight road safety.
"It’s even made my mum buy extra reflective things for my daughters’ school coats."
And the colour of school coats is an issue she feels needs highlighting.
Danielle, whose branch covers the whole of south Manchester, added: "A lot of people have pointed out that many schools have a dark coat dress code.
"It would be great if we could raise more awareness within schools regarding their policies."
