Where should handcuffs be applied on a subject?

Handcuffs should be applied at the narrow part of the wrist for several reasons related to safety, control, and effectiveness. This area provides a secure fit that minimizes the risk of injury to the individual being restrained. When handcuffs are placed in the correct position at the wrist, they can effectively limit a person's movement while also distributing pressure evenly. This helps prevent discomfort and potential nerve damage that can occur if handcuffs are applied higher up on the arm or in areas where there is more muscle and padding, like the forearm or upper arm.

Additionally, applying handcuffs at the narrow part of the wrist allows for better control by allowing law enforcement officers to maintain a secure hold on a subject while they are being detained. The design of handcuffs is intended to work optimally at this point, which also aids in quickly securing individuals without excessive struggle or resistance.
