"I just feel like it’s not totally clear of why the horse has bolted in the first place. Perhaps the easiest thing would be to change the wording to something more past tense – eg: 'Dear Driver, if given a fright, a horse may take flight', 'Dear driver, a fright on the road can send a horse into flight mode' or 'A horse frightened by your driving can send it’s handler flying'." - Comment From User Testing
