Active restraint device refers to which of the following?

• A. A device you must engage, such as a safety belt
• B. An automatic airbag deployment
• C. A seat adjustment switch
• D. A crash sensor

Answer: (A)

Active restraints are devices you must actively use to hold yourself in place during a crash. A safety belt fits this, because you buckle it yourself before or during travel, providing the restraint only when you engage it. In contrast, airbags deploy automatically without any action from you, so they’re considered passive restraints. The seat adjustment switch isn’t a restraint at all—it changes seat position. The crash sensor is a component that tells the system when to deploy restraints, not a restraint itself. So the device you must engage, such as a safety belt, is the active restraint.
