Specific prisoner transport restraints (e.g. Smith & Wesson model 1850 "transport restraint") are combinations which consist of a pair of handcuffs, attached by a longer chain to a pair of leg irons. When being placed in such transport restraints, the prisoner will still have the possibility to manage normal steps, but is prevented from running by the leg irons. The connecting chain also prevents the prisoner from lifting their arms. For transporting prisoners by car, special combinations called "auto restraints" are used where the chains of the leg irons as well as the connecting chains are shortened, allowing the prisoner only a stooping shuffling walk when he or she is outside the car.
