What should a Class E driver do if the draft animal becomes frightened or spooked (espanto del animal) by loud traffic noise or a barking dog?

1. Jump off the cart and run away
2. Maintain a firm, steady, and calm grip on the reins, speak in a low soothing voice, apply the cart friction brake to prevent runaway acceleration, guide the animal away from the hazard, and if necessary, have an assistant hold the bridle near the bit
3. Whip the horse vigorously
4. Sound an air horn into the horse's ear
