Which device is specifically designed to reduce neck injuries and is commonly required in race cars?

Explanation:
In a crash, limiting how far the head can move relative to the spine is key to preventing serious neck injuries. The HANS device is a rigid neck restraint that sits behind the neck and connects to the helmet with tethers. When a car decelerates suddenly, it prevents the head from snapping forward or to the side, transferring crash forces into the torso and reducing the load on the neck and spine. This targeted protection is why racing organizations commonly require it in race cars. While a helmet protects the head and a roll cage guards the cabin, neither specifically limits dangerous head movement in a crash like the HANS device does.
