THE UK HIGHWAY CODE OF PRACTICE regulates and maintains the rules for animals in the road (e.g. horses or dogs) and for operators of horse-drawn vehicles - including the riders.
The standards maintained by the Department for Transport's Highway Code Practice sets out the regulations and guidelines for operating horse-drawn vehicles.
The highways code also relates to the safety for horse riders and restrictions for other animals on public roads within the United Kingdom.
The requirements focus on a list of carriage and fittings safety checks for good working order, and a road driving assessment which may be subject to a Local Authority for passenger-carrying services.
All vehicles pulled by a horse should display two red reflectors on the rear of the carriage. The law also states that a light which is white at the front and red at the rear Must be fitted when driving a horse-drawn vehicle at night.
The Highway Code for horse riders states that whenever possible you should ride with other calm horses if you expect your horse to act nervously around traffic and always use your saddle and bridle.
Herded animals should always be kept under control. Try to warn other road users by having someone a distance in front of the herd. This is especially pertinent at the brow of a hill or around a bend.
Moving a large herd of animals is often safer done at night time in the darkness. You should wear reflective clothing and carry lights which display white at the front and red at the rear of the herd.
