This is a broad question. It depends on how a particular horse is trained, what it has been exposed to and habituated to, etc. Usually horses get frightened by sudden movements, sudden loud noises, and a sudden sharp pain inflicted on it. Inanimate objects can scare it too if it hasn't seen that particular object before.
A horse's first instinct when frightened or startled is to run away. The second instinct is to fight in order to protect itself.

To run. The first thing a horse will do when frightened is to run. If they feel trapped then they will fight by rearing and by kicking. Its called "Fight or flight". Fight or run. A horse will bolt (run) and can squeal. If a horse is really scared, or has fear, there would be little whites in their eyes.
