Horse riders are entitled to use the road and ROSPA argues that it is the responsibility of both riders and motorists to act responsibly.
Even though horses are big and strong they are still easily frightened. In fast-moving traffic or anywhere where there are sudden loud noises, it's not unusual for a horse to panic, no matter how well trained they are. It is difficult to ascertain accurate statistics for road accidents involving horses. However, the British Horse Society estimates that there are 3,000 such accidents each year, around half of which occur on minor roads.
