Final answer:
When a vehicle is about to be hit from the side, the motorist should keep a tight grip on the steering wheel to maintain control and minimize movement or injury.
Step-by-step explanation:
If a vehicle is about to be hit from the side, it is generally advised that the motorist should keep a tight grip on the steering wheel. This helps the motorist maintain as much control as possible during and after the impact. It is also important to brace for impact by pressing your back against the seat and your head against the headrest to minimize movement and potential injury. While vehicle safety features such as airbags and crumple zones are designed to absorb impact and protect occupants, keeping a firm grip on the steering wheel and bracing can reduce the risk of additional injuries caused by loss of control or being thrown around inside the vehicle.
