Horse riders are being encouraged to wear high-visibility clothing as part of a campaign to cut road deaths.

Thames Valley Police said wearing fluorescent and reflective clothing can give motorists an extra three seconds' notice that a horse and rider are ahead.

The campaign was launched on Tuesday at Oxford Equestrian Centre, Garsington, with the help of the British Horse Society (BHS).

British Olympic three-day eventer Ginny Elliott and London's Burning actor Glen Murphy, a horse rider and BHS member, were on hand to support the campaign.

Three people have died in the Thames Valley area in horse-related collisions since 1998 and 58 seriously injured. Five riders die each year on Britain's roads.

Police and the BHS are advising riders to take the BHS Riding and Road Safety Test, and are asking motorists to slow down and give horses plenty of room to avoid startling them.
