The British Horse Society has welcomed the prosecution of a man in a case of "horse rage" in Gloucestershire.
Eric James, 72, from Clifford's Mesne, was fined £250 and given eight points on his driving licence for intimidating two horses and their riders.
Coleford magistrates heard he sounded his horn loudly and was abusive after becoming stuck behind them in Newent.
Anna Camilleri, from the British Horse Society, said motorists should be patient with horses on the road.
"There are many areas where the only access to the countryside is via a road," she said.
"Obviously, we don't want to be on a road, but there are some incidents where you have to be."
The court heard that the horses became distressed by James' behaviour.
One of the riders, student Kelly Salter, said: "They were climbing up the hedge, they were going forward and back, they didn't know what to do, they needed calming down."
She said James had raised his fists and threatened to "get them" if he became stuck behind them again.
Sarah Forrow from the RAC said: "It's irresponsible for a motorist to be honking at horses, they are unpredictable animals.
"Motorists should be more tolerant and give them the room they need and pass safely and slowly or else it could result in people coming off their horses."
