Bridles

It is unsafe to tie a horse using a bridle for two main reasons. First, if the tied animal pulls back on the bridle, the bit or controlling noseband will cause considerable pain or even injury to the animal, and second, compared to halters most bridles are made of thinner leather and will easily break under pressure.

Despite what is commonly seen in movies, a horse should never be tied with the reins of a bridle to a solid object, as it could pull back and not only break the reins or bridle, but also severely injure its mouth, tongue, jaw or neck. This is also true for cross-tying a horse. Should a rider need to tie a horse, it is best to either remove the bridle and put on a halter, or to put a halter on in addition to the bridle (under or over the bridle), but in either case, tie the horse using the halter only.

A hackamore, put simply, is headgear that has a nosepiece for control instead of a bit. A hackamore is not the same thing as a halter, as a halter is primarily used for leading and tying up an animal. Bitless bridles are similar to hackamores, but some designs use different leverage principles for control. Hackamores and bitless bridles use a headstall with reins attached to some type of noseband or nosepiece. Various designs allow control and good communication to the horse and may, in come cases, be more comfortable to the horse, particularly a young animal or one with a mouth injury. Source
