You should abstain from using your horn at alland anywhere near a horse and rider! The reason is that you will upset the horse, potentially causing injury not not just the horse, but the rider as well. You may even kill a horse too if it has to be put down from a broken leg which may not be able to be fixed.
The other reason, in direct answer to the question, that you should never honk your horn behind a horse--even if you think it's just "for the fun of it" is that the horse could upset, turn right in front of you and run into your vehicle, or vice versa, causing damage to your vehicle and serious injury to both horse and rider.
You should never blow a car horn behind a horse and rider on the roadway because it can spook (scare) the horse and cause it to run into traffic and get itself and it's rider hurt or killed which you would be responsible for. You could startle a bicyclist.
Slow down. Wait for a clear passage to go around them. If you cannot safely pass, slow down, maintain clear distance behind them, and enjoy the horse's trot or wheel rotations of the bike.
NOTE: Same rule applies for Amish horse & buggy, or agricultural equipment moving in the right lane on a roadway. Be patient, slow down, wait for a safe time to pass. Do not honk.
There are many reasons not to use a horn directly behind a on the side of the roadway. This is not safe for starters.
This is typically a traffic safety law to prevent scaring the horse which could bolt into traffic and cause many injuries or deaths.
Ok, I won't
Stay behind the bicyclist until you can safely get around him.
Stay well behind the bicyclist until he turns off or gets in a designated bike lane. If you have a lane next to you, make a lane change and pass him when it is safe and legal to do so.
If you are traveling east there is no way Texas can be in front of you and NY behind you.
A bicyclist is not required to move ifthey are traveling at the speed of traffic and are not causing an obstruction.or they have no vehicles behind them.or they are in a clearly marked Bicycle lane.or they are making a left hand turn.or they are crossing an intersection.
You are charged, and responsible. The law in every state requires the driver entering the roadway to yield to traffic travelling on the roadway.
