A car with deployed airbags is not immediately drivable and is unsafe to operate. While the core mechanical functions might still allow movement, the safety systems are compromised, rendering the vehicle unsafe for the road.
When airbags deploy, it signifies a significant impact has occurred. The primary concern isn’t just the visible aftermath, but the unseen damage and the compromised safety features. Driving a car after the airbags fired vehicle has been in an accident is a complex issue with many factors to consider. While the engine might still turn over and the wheels can spin, the vehicle’s ability to protect occupants in a subsequent collision is severely diminished. This post will delve into why driving such a vehicle is ill-advised and what steps are necessary to assess its safety.

The Immediate Aftermath: What Happens When Airbags Deploy?
Airbags are a critical component of your car’s airbag system safety. They are designed to inflate rapidly during a collision, providing a cushion between the occupant and hard surfaces like the steering wheel, dashboard, or door panels. This deployment is a violent, instantaneous event triggered by sensors that detect rapid deceleration.
When airbags deploy, several things happen:
- Inflators release a fine powder: This powder is typically cornstarch or talcum powder, used to prevent the airbag from clumping and to help it unfold smoothly. It can cause skin irritation for some individuals.
- The airbag itself: Made of nylon fabric, it inflates with nitrogen gas. The force of the airbag can cause minor abrasions or bruising.
- Sensors and electronics: The impact that triggers airbag deployment also affects the vehicle’s sensors and electronic control modules.
Why Driving a Post-Airbag Deployment Car is a Bad Idea
The question of whether you can drive a car after its airbags have deployed is not a simple yes or no. The answer leans heavily towards no, not safely. Here’s why:
Compromised Safety Systems
The most crucial reason not to drive a car with deployed airbags is that its primary safety systems are now inoperable. The airbags are a one-time use item. Once they have fired, they cannot be reinflated. This means that in any subsequent impact, the occupants will not have the protection that airbags provide.
The Airbag Warning Light On
Often, after airbags deploy, the airbag warning light on the dashboard will illuminate and remain lit. This light is a clear indicator that the airbag system has malfunctioned or has been activated and is no longer functional. Driving with this light on is a significant red flag.
Potential for Further Damage
An accident severe enough to deploy airbags can cause hidden damage that isn’t immediately apparent.
- Structural Integrity: The impact might have compromised the vehicle’s frame or structural components. Even minor damage to the chassis can affect how the car handles and performs in future incidents.
- Suspension and Steering: Components of the suspension and steering systems could be damaged, leading to alignment issues, vibrations, or reduced control.
- Braking System: While less common, a severe impact could potentially affect the braking system, a critical safety feature.
Airbag Sensor Damage
The deployment of airbags is controlled by a complex network of sensors strategically placed throughout the vehicle. An accident can cause airbag sensor damage, leading to either accidental deployment or, more critically, failure to deploy in a future collision.
- Faulty Readings: Damaged sensors might send incorrect signals to the airbag control module, potentially causing further system malfunctions.
- System Inactivation: If a key sensor is damaged, the entire airbag system might be rendered inoperative, even if the physical airbags themselves are replaced.
Airbag System Malfunction
Beyond sensor damage, the central airbag system malfunction can occur due to the impact. The airbag control module (the “brain” of the system) might have been affected by the shock of the collision. This could lead to unpredictable behavior of the remaining safety systems.
Assessing the Drivability After Airbag Deployment
So, while the car might physically move, the question of being drivable after airbag deployment needs careful consideration. It’s less about whether it can move and more about whether it should be moved.
What to Do Immediately After an Accident with Airbag Deployment:
- Ensure Everyone is Safe: Check for injuries and call emergency services if necessary.
- Do Not Attempt to Drive: The vehicle is compromised.
- Contact a Tow Truck: Have the vehicle professionally towed to a reputable repair shop or dealership.
- Notify Your Insurance Company: Document the damage and initiate the claims process.
Professional Assessment is Key
A thorough inspection by a qualified mechanic or collision repair specialist is essential. They will look for:
- Physical Damage: Any visible damage to the body, frame, and interior.
- Sensor Functionality: Checking the status and integrity of all impact and occupant sensors.
- Airbag Control Module: Ensuring the module is functioning correctly and has not been damaged.
- Electrical System: Verifying that all electrical components, especially those related to safety, are intact.
- Mechanical Components: Assessing the condition of the engine, brakes, steering, and suspension.
The Repair Process: Airbags Deployed Repair
If a vehicle with deployed airbags is deemed repairable, the airbags deployed repair process is extensive and specialized. It involves more than just replacing the deflated airbags.
Components Requiring Replacement:
- Airbags: All deployed airbags must be replaced with new, genuine parts. This includes driver’s side, passenger’s side, side curtain airbags, and knee airbags, depending on the vehicle’s configuration.
- Airbag Control Module (ACM): The ACM often needs to be replaced or reprogrammed as it stores crash data and is the central hub for the airbag system.
- Sensors: Any damaged or suspected faulty sensors must be replaced.
- Seatbelt Pretensioners: In many vehicles, seatbelt pretensioners also deploy during a collision, and these must be replaced.
- Clock Spring: This component in the steering wheel connects the airbag to the vehicle’s electrical system. It often needs replacement if the driver’s airbag deploys.
- Dash and Steering Wheel Coverings: The plastic covers that housed the airbags will be torn and must be replaced.
- Wiring Harnesses: Any damaged wiring related to the airbag system needs to be repaired or replaced.
The Complexity of Airbag System Reset
It’s important to note that simply replacing the airbags is insufficient. The vehicle’s computer system needs to be reset to acknowledge the new components and clear the crash data from the ACM. This is part of the airbag system reset process, which requires specialized diagnostic tools. Attempting a simple reset without replacing faulty components can lead to a malfunctioning airbag system.
Can You Drive A Car With Deployed Airbags? The Verdict
To reiterate: No, you cannot safely drive a car with deployed airbags.
Here’s a summary of why:
| Reason | Explanation |
|---|---|
| Compromised Safety | Airbags are a critical safety feature and will not function in a subsequent impact. |
