SPEED
10 mph at most
Rule 215 says that when you see a horse on a road you should slow down to a maximum of 10 mph, be patient and not sound your horn or rev your engine.
Check a situationA horse on the lane needs your patience, not your horn.
Since January 2022 the Highway Code has asked drivers to slow to 10 mph at most when they see a horse, and to pass wide and slow, leaving at least 2 metres. Riders have their own rules too.

Check a situationTHE SHORT ANSWER
Slow to 10 mph,
then pass wide.
Horses are flight animals.
Speed and space are what the guidance comes back to.
SPACE
At least 2 metres
When it is safe, pass wide and slow, allowing at least 2 metres. If you cannot give that space, the Code says wait behind and do not overtake.

RIDERS
Be seen, keep left
Riders should wear light-coloured or fluorescent clothing by day and reflective kit in poor light, keep to the left and give clear arm signals.

IF YOU ARE THE RIDER
Your side of
the road safety deal.
The Highway Code has a section for horse riders too. These are the basics from rules 49 to 55.
Helmet and hard-soled boots
Children under 14 must wear a helmet that meets the regulations, fastened securely. Other riders should follow the same requirements.
Dress to be seen
Light-coloured or fluorescent clothing in daylight, reflective clothing at night or in poor visibility, and reflective bands on the horse.
Keep left, signal clearly
Look behind before moving off or turning, give a clear arm signal, and ride single file on narrow or busy roads and round bends.
Stay off pavements
You must not ride on a footpath or pavement. Use a bridleway where possible, and avoid roundabouts where you can.
THE HIERARCHY OF ROAD USERS
Greater harm,
greater responsibility.
Rule 204 lists horse riders among the road users most at risk from traffic, alongside pedestrians, cyclists and motorcyclists. It says those who can cause the greatest harm have the greatest responsibility to reduce the danger they pose.
Rule 215 adds that there are three brains at work when you pass a horse: the rider's, the driver's and the horse's. Horses are flight animals and can move incredibly quickly if startled, whatever the rider does.
Questions
Questions people ask
How fast should I drive past a horse?
Rule 215 of the Highway Code says to slow down to a maximum of 10 mph when you see a horse on a road, and to pass wide and slow when it is safe.
How much space should I give a horse?
At least 2 metres, passing wide and slow. Rule 163 says to give more space in bad weather, including high winds, and at night, and to wait behind if you cannot give that clearance safely.
Why do riders sometimes ride in the middle of the lane?
Rule 213 says that on narrow sections of road horse riders may ride in the centre of the lane so they can see and be seen, and drivers should allow them to do so.
Can horse riders ride two abreast?
Rule 53 says never more than two abreast, and single file on narrow or busy roads and round bends. Rule 215 notes riders may ride double file when escorting a young or inexperienced horse or rider.
When did these rules change?
The Highway Code was updated on 29 January 2022. The British Horse Society says its Dead Slow messages, including the 10 mph and 2 metre guidance, were incorporated in that update.
