What Speed Do Airbags Deploy?

Muhammad Ramadan | February 24, 2025 | Car Accident

Airbags are an important component of vehicle safety. They deploy during a collision to reduce the risk of serious injuries. Various factors determine when and how airbags deploy. Knowing how airbag deployment works helps drivers understand the importance of these safety features.

How Airbag Deployment Speed Is Determined

Sensors in the airbag system primarily determine the speed at which the airbag deploys. These sensors monitor the deceleration of the vehicle during a crash. When deceleration reaches a threshold—typically around 16 mph—the sensor triggers the airbag deployment. This system deploys the airbags quickly to cushion the occupant’s impact against the steering wheel or dashboard, reducing the risk of injury. The efficiency of the deployment ensures the safety of everyone involved in the crash.

The design of the airbag system also influences the deployment speed. Most airbags deploy in frontal collisions, while side airbags activate in side-impact situations. This sophisticated engineering ensures that the airbag deploys at the appropriate speed for the severity of the crash, providing maximum protection.

Factors That Affect Airbag Activation

Several factors can affect airbag activation during a collision. The severity of the crash is one of the most important factors. If the impact does not reach the threshold for deployment—around 16 mph—the airbags may not deploy. The vehicle’s airbag system is designed to deploy only in moderate to severe collisions. The angle of the crash also plays a role. Frontal airbags are designed for head-on collisions, while side airbags activate in lateral impacts.

The condition of the airbag system itself can also influence deployment. A faulty or defective airbag may fail to deploy, putting occupants at risk. Regular maintenance checks and understanding how the airbag system works help ensure it functions properly when needed.

The Speed Threshold for Front and Side Airbags

Front and side airbags have different speed thresholds for deployment. Front airbags typically deploy when the vehicle decelerates rapidly at around 16 mph or greater in a frontal collision. This threshold helps ensure the airbag deploys only in situations where it can effectively reduce the risk of injury. Side airbags, on the other hand, may deploy in lower-speed collisions, depending on the impact and angle of the crash.

The design of the airbags is tailored to the specific dynamics of different types of collisions. Side airbags may deploy in minor collisions to protect against side impacts.

Common Injuries Caused by Airbag Deployment

Airbags are designed to reduce the risk of serious injuries in a crash, but they can still cause harm during deployment. Common injuries include abrasions and bruises, especially on the face and arms, due to the rapid inflation and force of the airbag. In some cases, more serious injuries, such as concussions or fractures, can occur if the airbag fails to deploy correctly or if the occupant is improperly positioned.

Why Some Airbags Fail to Deploy in a Crash

Airbags may fail to deploy for several reasons. One reason is that the crash’s severity does not reach the necessary threshold for deployment. If the impact is below 16 mph, the airbag system may determine that deployment is unnecessary. A faulty airbag system can also prevent deployment. Improper maintenance can also lead to airbag failure. If the airbag has been deployed previously and not replaced, or if there are sensor issues, the airbag may not function correctly.
