What should be noted regarding the desired protective effect of airbags?

You answered correctly. Airbags are designed to provide maximum protection only when passengers are sitting in the correct position and not leaning too close to the dashboard, steering wheel, or airbag deployment area. It’s also important to keep the airbag deployment zone clear—objects or improper body positioning in this area can reduce the airbag’s effectiveness or even cause injury during deployment. However, airbags cannot replace seatbelts; both are needed for optimal safety, no matter the speed or location of your drive. Always use your seatbelt in combination with airbags, and make sure your seating position doesn't interfere with proper airbag function.
