When should handcuffs be double-locked?

When should handcuffs be double-locked?

• A. When tactically safe to do so
• B. Immediately upon securing
• C. After transporting to a court
• D. Never

Answer: (A)

Double-locking is a safety step that prevents handcuffs from tightening further and reduces the risk of injury if the detainee pulls or swells. The best practice is to apply the double-lock when you can do so without compromising control of the situation. In other words, once the subject is secured and you have the scene under control, reach the double-lock mechanism and set it. This prioritizes safety and control first, then the restraint mechanism. If you wait until transporting to a court, you’re exposing the person and the officer to unnecessary risk during movement. While some teams aim to double-lock promptly after securing, doing it at the point you can perform it safely is the most reliable approach. Avoid delaying beyond when you can maintain control, and never skip the step, as improper or absent double-locking can lead to injury or ease of escape.
