How a Collision Can Affect Your Vehicle’s Advanced Safety Features
Your car has stopped after a crash, but you are unsure whether the air bags still work. Even if the vehicle runs, collision damage can affect protection for drivers and passengers.
Checking the safety system is part of safe repair, not just a way to fix visible damage. A crash sensor is an electronic component that detects crash forces and helps signal the air bag system.
This guide explains deployment, non-deployment, repairs, and recall checks. The first step is understanding how crash sensors trigger deployment.
Key Takeaways
- Do not drive after an air bag deploys.
- Have a qualified technician assess the restraint system.
- A non-deployment does not alone prove a system defect.
- Check your vehicle identification number for open recalls.
- Use genuine OEM parts for replacement.
What Happens to Airbags After Collision?
A frontal air bag inflates in less than 1/20 of a second. Rapidly, crash sensors send signals through the system, and an inflator creates gas to fill the bag.
The electronic control unit can signal an inflator during a moderate-to-severe crash. Its igniter starts a chemical reaction that produces gas and fills the air bag.
Frontal and side air bags are generally designed for moderate-to-severe crashes, but they may deploy in some minor crashes. Crash direction, impact details, system design, and crash-sensor locations all affect deployment.
How an Airbag in a Car Works
Knowing how an airbag in a car works can help explain why two similar crashes produce different results. Vehicle-specific thresholds matter, so non-deployment alone does not prove a defect.
The response to airbags after collision in 2021 remains vehicle-specific, not governed by a special rule for that year. Passenger vehicles may have frontal, side, and rollover curtain bags in different locations.
| Air bag type | Typical crash direction | Typical location | Protection purpose |
|---|---|---|---|
| Frontal | Frontal or near-frontal crashes | Steering wheel or dashboard | Cushions head and upper body |
| Side | Side impacts and some frontal crashes | Seat or roof area | Cushions head and chest |
| Rollover curtain | Detected rollover | Roof rail | Covers window opening and helps limit ejection |
Can You Open an Airbag Manually?
You cannot manually open an air bag to make it deploy. Do not try to service one yourself, since inflators and stored energy can cause harm.
Side curtain bags designed for rollovers can remain inflated for 10 or more seconds. That extended coverage may help protect occupants and reduce ejection risk.
The question of how to open an airbag in a car accident has a clear answer: you cannot safely trigger one by hand. Knowing how deployment works leads to what you should do right after it happens.
What Should You Do Immediately After Airbags Deploy?
Treat a deployed air bag as a reason to stop driving and check for injuries. First, protect yourself and other occupants, and do not drive the vehicle until it is repaired.
Follow these steps in order when you can do so safely:
- Check yourself and passengers for injuries.
- Call 911 if anyone is hurt or the crash needs emergency response.
- Move away from traffic if you can do so safely.
- Arrange a tow instead of driving a vehicle with deployed air bags.
- Get medical attention for concerning symptoms, even if they appear later.
Seat belts remain essential because air bags work with, not instead of, proper restraints. Children under 13 should ride in the back seat, where they stay farther from a front air bag.
When practical, drivers should keep at least 10 inches between the center of the steering wheel and their chest. A safe position helps lower the risk of injury as an air bag deploys.
Do not touch deployed components or treat loose debris as a repair task. A qualified technician must assess the parts and system before the vehicle returns to service.
Which Parts Need Inspection or Replacement After Deployment?
Yes, can airbags be replaced after an accident? Yes, deployed air bags must be replaced, not repaired for reuse. Each deployed bag is single-use and needs a genuine OEM replacement.
An authorized repair technician should replace each deployed bag without delay. Counterfeit bags can fail to deploy or release metal fragments, so use an authorized repair center.
Crash sensors and related parts also need assessment under the vehicle maker’s repair procedures. A technician should not assume every sensor or control module needs replacement.
Which Air Bag and Restraint Parts Need Replacement?
A deployed bag cannot be repacked or reused. The repair shop should fit a genuine OEM part that matches the vehicle and the affected position.
The full restraint system may need checks beyond the visible air bag. Wiring, connectors, and related parts should be assessed based on the crash and the maker’s repair steps.
What Should a Technician Inspect if an Air Bag Did Not Deploy?
Deployment is not expected in every crash, so a non-deployment alone does not show a fault. If an injury-producing crash occurred, ask a qualified technician to investigate the system.
An air bag that fails to deploy in an injury-producing crash should be reported to NHTSA’s Office of Defects Investigation. Keep records of the crash and repairs for your review.
Use this repair-check list when you discuss the work with the repair shop:
- Identify which bags deployed.
- Inspect crash sensors and related wiring under vehicle-specific procedures.
- Confirm replacement parts are genuine OEM parts.
- Document completed repairs and system checks.
That repair scope helps show what remains before the vehicle can return to the road. The next question is whether it is safe to drive before the work is complete.
Is a Vehicle Still Drivable if Airbags Deploy?
No, do not drive a vehicle with deployed air bags until repairs are complete. Once used, a bag cannot protect you a second time, and the vehicle needs a tow.
The restraint system has lost some or all of its intended protection. A visible dent may not show the full condition of crash sensors or other parts.
Driving puts the driver, front passenger, and people in the rear seat at added risk. Other damage from the impact may also affect how the vehicle handles or stops.
Arrange a tow to a repair shop rather than driving there, even if the engine starts. A technician can check the vehicle and complete required repairs before you use it again.
Once you know the vehicle needs repair, you can consider the financial decision: the estimate, insurance coverage, and possible total loss.
How Much Does Airbag Repair Cost, and Is the Car a Total Loss?
Two vehicles from similar crashes can have different estimates because their damage and deployed parts differ. There is no set price for the cost of replacing airbags after an accident, and an inspection is needed for a vehicle-specific estimate.
The estimate depends on the vehicle, the number and type of bags that deployed, and collision damage that also needs repair. A repair shop can assess the vehicle and prepare an estimate based on its condition.
What Affects the Airbag Repair Estimate?
Parts and labor can vary with the vehicle and the work required after the crash. Damage to the body, interior, wiring, or other safety parts can add to the repair scope.
Ask the repair shop to explain the estimate in clear terms. You can compare the listed work with the damage the technician found, rather than relying on the air bag count alone.
How Do Insurers Decide Whether to Repair or Total a Car?
Air bag deployment alone does not mean a vehicle is totaled. The insurer compares repair costs with the vehicle’s value and applies the policy and state rules.
No single threshold or outcome applies to every car and claim. Your insurer’s decision depends on the estimate and the rules that apply to your policy and state.
“Worth fixing” is your personal financial choice, while a total-loss decision belongs to the insurer. You can weigh the repair estimate, vehicle value, and your needs separately.
Financial questions can feel less clear than the damage you see. Deployment also creates physical risks, so pain or other symptoms deserve attention.
What Injuries Can Airbag Deployment Cause?
Air bags save lives, but their rapid force can also cause injury. Most people are protected when seated and belted, yet close contact as a bag opens can cause harm.
Possible side effects of airbag deployment in a car accident include bruises, cuts, burns, and head or chest injuries. Hot gases released during deployment can also hurt occupants.
An air bag can fatally injure a child in some circumstances, especially when a child sits too close to an active frontal bag. For child safety, follow the vehicle and child-seat instructions, and keep children under 13 in the back seat.
NHTSA estimated more than 290 deaths from frontal air bag inflation in low-speed crashes during 1990-2008. Nearly 90% involved vehicles made before 1998, and more than 80% of those killed were unbelted or improperly restrained.
Those figures describe deaths involving older-generation air bags, not a current risk estimate. If you have pain, trouble breathing, burns, or other concerning symptoms, seek medical evaluation.
After your health needs are addressed, verify the repairs and check for recalls before arranging the vehicle’s return to service.
How Do You Verify Airbag Repairs and Check Recalls?
Check your vehicle identification number in NHTSA’s recall database for open recalls. Start with the VIN, and contact the dealer about any open air bag recall.
Authorized service centers perform recall repairs free of charge. Ask the collision center to document replaced bags, the source of OEM parts, and system checks under vehicle-specific procedures.
How to Check for an Air Bag Recall
Use NHTSA’s vehicle recall database to search your vehicle identification number. If the search shows an open air bag recall, contact a dealer to arrange the repair.
An air bag ON-OFF switch is not a routine way to work around a fault. NHTSA authorizes switches only for four narrow high-risk circumstances, and only authorized dealers or repair shops may install them with NHTSA authorization.
- A rear-facing infant restraint must use a front seat because no suitable rear seat exists.
- A child must sit in front for frequent medical monitoring.
- A medical condition makes deactivation safer.
- A driver must sit within a few inches of the bag, often due to very short stature.
How to Confirm Replacement Parts and Repairs
Ask the collision center for written records of parts and system checks. The records should name the replacement bags, show the OEM parts source, and describe checks done under the vehicle maker’s procedures.
No standard average can be given for an air bag non-deployment settlement. A claim depends on the specific injury, evidence, and applicable law, so seek legal advice from a qualified attorney.
| Situation | Safety concern | Appropriate next step |
|---|---|---|
| Open recall | Defective air bag inflator | Ask the dealer for recall repair |
| Counterfeit replacement part | Possible non-deployment or metal fragments | Request part-source documentation |
| Air bag ON-OFF switch | Not a routine repair | Seek NHTSA authorization only for a qualifying case |
Once you have checked the records and any recall, arrange collision repairs with a qualified local center.
