Hannah Mudd made campaign posters and flyers, with the slogan, 'We don't dent, we DIE', to raise awareness of the problems horses and their riders face on busy roads in the Funtington area.

After the youngster campaigned to councillors last year, asking 'Why should someone like me have to die before something can be done?', West Sussex County Council decided to take action.

Hannah was initially allowed to display her own laminated posters in the Funtington area.

The eye-catching posters with her safety message to motorists were free for anyone who wanted to display them by a roadside near their home.

As an outcome of Hannah's campaign, the council has installed two road signs along the Funtington straight B2178 on the east, and westbound at the junction with the B2146 Southbrook Road.

The horse and rider red triangular signs aim to warn drivers of the possible presence of horses in the road ahead.

A council spokesman said: "Hannah raised some important safety issues."

Hannah, who has been riding around the lanes in the West Stoke and Funtington area for more than two years, said: "Hopefully the signs will help to make drivers slow down."

County cabinet member for the environment and economy Cllr Louise Goldsmith, who represents Chichester West, said: "We all need to enjoy the countryside. We just wish drivers would slow down and understand horses do leap around – and it's dangerous."
