What Are Airbags?

Airbags are inflatable cushions that deploy during a collision to reduce the risk of injury. They work by rapidly inflating upon impact, creating a barrier between the occupant and the hard surfaces of the vehicle. This protective measure absorbs and distributes the force of a crash, particularly benefiting front-seat passengers. Generally, you’ll find airbags in passenger vehicles, but their presence in semi trucks varies significantly.

Types Of Airbags

Airbags come in various types, each designed for specific purposes:

1. Frontal Airbags:

Frontal airbags deploy from the steering wheel and dashboard, providing protection during head-on collisions.

1. Side-Impact Airbags:

Side-impact airbags inflate from the vehicle’s side doors or seats. They protect occupants during side collisions, a critical feature for all vehicle types.

1. Curtain Airbags:

Curtain airbags drop down from the roof area, forming a protective barrier along the side windows. These airbags are essential for protecting heads during side crashes and rollovers.

1. Knee Airbags:

Knee airbags deploy below the dashboard to protect the knees and lower legs during a frontal collision. They contribute to overall safety by minimizing the risk of leg injuries.

In semi trucks, the use of airbags varies by model and manufacturer. Some advanced trucks may integrate limited airbag systems, while many still rely on other safety features without comprehensive airbag technology. Understanding these differences is key for drivers and operators when evaluating vehicle safety.
