A halter and lead rope
To move a horse from one place to another you should use a halter and lead rope.
a horse trailer..
You should never, ever walk in front of a horse when leading it! This is a dangerous place to be should the horse spook or attempt to run you over. You also cannot see the horse and you have no control over him in that position. You should walk to the left of the horse, beside its neck, with the lead in your right hand. Think of the horses head, his shoulder and you between them as points on a triangle. From this position you can see your horses head and if he should spook you are out of his way. You also have control over him via the lead rope and if he pushes into you, you can use your elbow to move him over.
A rope halter is best....

Halter
A headcollar
Walk on the left side of the horse, do not leada horse by walking directly in front of it. Do not walk behind a horse unless you let it know you are there and either walk close to the tail (less then a foot between you and the horse) or far away (about 6ft between you and the horse) so it cannot kick.... There are many more, but you should be talking to a trained proffessional in person to collect info, not asking on wikianswers.
