Most of us get into a vehicle expecting to arrive safely at our destination. But what if the unexpected happens? What if the person driving suddenly experiences a medical emergency? A heart attack, stroke, seizure, diabetic emergency, or sudden loss of consciousness can happen without warning. In those critical moments, a passenger may become the only person able to reduce the risk of a devastating collision. While every situation is different, knowing what to do could make a life-saving difference.
Stay as Calm as Possible
Your first instinct may be panic, but taking a deep breath and acting quickly can help. A calm response allows you to think more clearly and make better decisions during an emergency. Sometimes a driver may recognize they are experiencing a medical issue and can safely steer the vehicle to the side of the road.
Try to Get the Driver’s Attention
If the driver appears confused or unresponsive:
- Call their name loudly.
- Ask if they are okay.
- Encourage them to pull over immediately if they are still conscious and able to respond.
Help Control the Vehicle Only If It Is Safe
If the driver becomes unconscious or can no longer control the vehicle, you may need to act immediately. Depending on where you are seated and whether you can safely reach:
- Carefully steer the vehicle toward the shoulder or away from traffic if possible.
- If you can safely reach the gear selector, shift the vehicle into Neutral. This can help slow the vehicle, although the engine will continue running.
- Once the vehicle has slowed significantly, apply the parking brake gradually if it is within reach. Avoid pulling it abruptly at high speed, as doing so could cause the vehicle to skid.
- Modern vehicles may have electronic parking brakes or other safety features, so their operation can vary.
Call 911 Immediately
As soon as it is safe to do so:
- Call 911.
- Tell the dispatcher that the driver is having a medical emergency.
- Provide your location, direction of travel, and any landmarks you can identify.
- Follow the dispatcher’s instructions. After the Vehicle Stops
Once the vehicle has come to a complete stop:
- Turn on the hazard lights if possible.
- Check whether the driver is breathing and responsive.
- Do not move the driver unless there is an immediate danger, such as fire or another life-threatening hazard.
Every Second Matters
Medical emergencies behind the wheel can happen to anyone, regardless of age or driving experience. Even simple actions such as calling 911 quickly, helping guide the vehicle to safety if possible, or staying calm may help prevent a tragedy.
Road Safety Is a Shared Responsibility
We often think about distracted driving, impaired driving, or speeding when discussing road safety. But medical emergencies are another reminder that unexpected situations can arise in an instant. Knowing what to do as a passenger doesn’t guarantee a perfect outcome, but it can improve the chances of protecting the driver, passengers, and everyone sharing the road. Yet every year, drivers experience unexpected medical events while behind the wheel and it’s a frightening situation to imagine.
At the Crash Support Network, we know that crashes happen for many different reasons. While some are preventable, others result from circumstances no one could have predicted. Regardless of the cause, the impact on crash survivors and their families can be life-changing. Every day, we hear stories from people whose lives changed in an instant. Some crashes involved distracted driving or impaired driving. Others involved weather, wildlife, mechanical failures or medical emergencies that no one could have predicted. None of us expect to become the passenger in a vehicle where the driver suddenly experiences a medical emergency. But by understanding the risks and being prepared to respond, we can all help make our roads safer.
