Airbags are one of the most critical safety features in modern vehicles, designed to protect you in the event of a collision. Since their introduction, they have saved countless lives and reduced the severity of injuries in accidents. However, just like any other part of your car, airbags can experience malfunctions or defects, which could put you at greater risk instead of protecting you.
At Get Drivers Ed, we stress the importance of understanding how airbags work, recognizing signs of a malfunction, and ensuring that your airbags are in good working condition. In this blog, we’ll explore how airbags function, potential risks you should be aware of, and how you can make sure your airbags are safe and ready to protect you when needed.
1. How Do Airbags Work?
The Science Behind Airbags
Airbags are part of your car’s passive safety system. In the event of a collision, they deploy almost instantaneously to create a cushion between you and hard surfaces like the steering wheel, dashboard, or side doors. Here’s a basic breakdown of how airbags function:
Sensors: Your vehicle is equipped with multiple sensors that detect a collision. These sensors measure the force of the impact and determine whether airbag deployment is necessary.
Inflator: Once a collision is detected, the airbag system triggers a chemical reaction in the inflator, generating nitrogen gas that fills the airbag.
Deployment: The airbag deploys in just a fraction of a second, inflating to provide a protective barrier. After the initial impact, the airbag quickly deflates to avoid suffocation or obstruction.
Airbags are designed to work in tandem with your seatbelt, so it's important to always wear your seatbelt when driving. At Get Drivers Ed, we emphasize the necessity of buckling up in every lesson, as airbags alone cannot provide complete protection without the support of your seatbelt.
Types of Airbags in Modern Vehicles
Modern vehicles come equipped with several types of airbags to protect you from multiple angles during a crash:
Frontal Airbags: These are the standard airbags that deploy from the steering wheel and dashboard during head-on collisions.
Side Airbags: These airbags are located in the doors or seats and are designed to protect passengers in the event of a side impact.
Curtain Airbags: These deploy from the roof to protect occupants' heads during side impacts or rollovers.
Knee Airbags: Located beneath the dashboard, these airbags protect the driver’s and front passenger's lower limbs in a crash.
Understanding how each of these airbags works and how they function in various crash scenarios is key to staying safe on the road.
2. Potential Airbag Issues You Should Be Aware Of
Airbag Recalls and Defects
Over the past decade, several significant airbag recalls have raised concerns about the safety of this crucial feature. One of the most notable was the Takata airbag recall, which affected millions of vehicles worldwide. The issue with Takata airbags was a faulty inflator that could cause the airbag to explode upon deployment, sending metal fragments into the car’s cabin. This defect led to several fatalities and injuries, prompting one of the largest recalls in automotive history.
Recalls like these highlight the importance of staying informed about the status of your vehicle's safety features. It’s essential to check whether your vehicle has been affected by any recalls and take immediate action if necessary. Many drivers are unaware of the recalls affecting their vehicles, so taking proactive steps can prevent a potential disaster.
At Get Drivers Ed, we educate drivers about the importance of vehicle recalls and regularly check their vehicle’s status using the National Highway Traffic Safety Administration’s (NHTSA) online recall database.
Airbag Warning Light
Your car's airbag system is designed to alert you if something is wrong. If the airbag warning light on your dashboard stays illuminated after you start the car, it means that there’s a problem with the airbag system. This could be due to a malfunction in the sensors, wiring issues, or a problem with the airbag module itself.
Ignoring the airbag warning light can be dangerous, as it could mean that your airbags won’t deploy properly in the event of a crash. If you see this light, it’s important to have your vehicle inspected by a professional mechanic right away.
Age and Wear of Airbags
While airbags don’t have a specific expiration date, the components of the system can deteriorate over time. Older vehicles, especially those over 10 years old, may have outdated or malfunctioning airbags due to wear and tear. If you drive an older car, it’s a good idea to have the airbag system inspected periodically to ensure it’s still functioning as intended.
Additionally, if your vehicle has been in a previous accident and the airbags deployed, they will need to be replaced. Make sure that any airbag replacement is done by a certified professional to guarantee proper installation.
3. How to Ensure Your Airbags Are Safe
Check for Recalls Regularly
As mentioned earlier, one of the most important steps you can take to ensure your airbags are safe is to check for recalls. You can do this by visiting the NHTSA website and entering your vehicle identification number (VIN). If your vehicle is part of a recall, contact your local dealership or manufacturer to schedule a repair as soon as possible. Most recalls, including those involving airbags, are repaired free of charge.
Routine Vehicle Inspections
In addition to checking for recalls, it’s a good idea to have regular vehicle inspections. During these inspections, a qualified mechanic can check the status of your airbag system and make sure everything is functioning properly. Even if there’s no visible issue or warning light, periodic checks can help identify any hidden problems before they become serious.
Be Mindful of Aftermarket Modifications
If you’ve made modifications to your car, particularly to the interior, it’s important to consider how those changes might affect your airbags. For example, changing the seats, dashboard, or steering wheel can interfere with the proper deployment of airbags. Always consult with a professional before making any modifications to ensure your airbags remain functional.
Replace Airbags After Deployment
If your airbags have deployed in a previous accident, they must be replaced. Driving without properly functioning airbags significantly increases your risk in the event of another crash. Make sure any airbag replacement is done by a certified professional to ensure proper installation and functionality.
At Get Drivers Ed, we educate our students on the importance of keeping their vehicles in top condition, including their safety features like airbags. Proper maintenance can be the difference between life and death in a collision.
4. What to Do in Case of Airbag Deployment
After an Accident
If your airbags deploy during a collision, it’s crucial to remain calm. Airbags can save your life, but they deploy with considerable force, which can cause minor injuries like bruising or burns. After the airbags have deployed:
Turn Off the Engine: In the event of a serious accident, turn off the vehicle’s engine to prevent further damage or hazards.
Exit the Vehicle Safely: If possible, exit the vehicle and move to a safe location away from traffic.
Seek Medical Attention: Even if you feel fine, it’s important to seek medical attention after an accident. Airbag deployment can cause injuries that may not be immediately apparent.
Get the Airbags Replaced: After an accident, the airbags must be replaced. Make sure the repairs are done by a certified professional to ensure they’ll function properly in the future.
