The sound is usually the first thing that sticks with you. It’s not like the movies. There’s no cinematic explosion or slow-motion glass shatter. It’s a sickening, heavy thud—metal meeting metal at high velocity—followed by a silence that feels way too heavy. Then, the screaming starts, or worse, the total lack of it.
If you find yourself pulling over, your heart is probably hitting your ribs like a trapped bird. You’ve just transitioned from a commuter to a first responder. It’s a heavy pivot. Honestly, most people have no idea what to do. They freeze. They grab their phones to record. Or they run toward the wreckage without looking at the traffic behind them.
Upon arriving at the scene of a motor vehicle crash, your brain enters a state of "tachypsychia." That’s the technical term for time dilation during a trauma. Seconds feel like minutes. This is where your training—or lack thereof—determines whether you’re helping or just adding to the chaos.
Safety First Is Not Just a Cliche
Before you even think about the victims, you have to think about the "hot zone." If you get hit by a distracted driver while trying to help, you’ve just doubled the workload for the paramedics. You’re no good to anyone if you’re a second casualty.
Park your car at least 50 feet away. Put your hazards on. If it’s dark, use your headlights to illuminate the scene, but try not to blind oncoming traffic. It’s a delicate balance. You want to be seen, but you don't want to cause another rubbernecking accident.
Check the ground. Is there fluid leaking? Most people assume it’s gas and it’s going to blow up like a Michael Bay film. Usually, it's just coolant or oil. But if you smell raw fuel, that’s a different story. Gasoline doesn't just catch fire; the vapors travel. If you see a pool of liquid under a car and it smells like a gas station, keep everyone back. No smoking. No flares. Just distance.

The Invisible Dangers
Power lines are the big ones. If a pole is down, stay away. Even if the wires aren't sparking, they can be "live." Electricity is weird; it can energize the ground around the vehicle or the metal of the car itself. If you touch a car that's in contact with a live wire, you’re dead. Period.
Then there are the airbags. If a car has crashed but the airbags haven't deployed, they are basically unexploded ordnance. They can go off minutes after the impact. If you’re leaning into a window to check a pulse and that bag fires, it can break your neck. It happens. Rescue crews call it the "5-10-20 rule"—stay 5 inches from side airbags, 10 from steering wheels, and 20 from passenger-side dash bags.
Assessing the Damage Without Losing Your Cool
Once the scene is "safeish," you need to triage. This is where it gets gritty. You’re looking for who needs help right now versus who can wait. It sounds cold, but it’s the only way to save lives.
Look for the "quiet ones." The person screaming about their broken arm is breathing. They have an airway. They have a pulse. The person slumped over the wheel who isn't making a sound? That’s your priority.
- Check for consciousness: "Hey! Can you hear me?" Don't shake them. If they have a spinal injury, shaking them could paralyze them for life.
- Look for catastrophic bleeding: We're talking arterial spurts. If you see bright red blood pulsing, you need a tourniquet or heavy pressure immediately. You have about two to three minutes before they bleed out.
- Airway check: Is their chin tucked into their chest? Gently lift the chin if they aren't breathing, but try to keep the neck as still as possible.
Dr. Peter Antevy, a renowned EMS medical director, often talks about the "handtevy" method in pediatric care, but the principle applies to everyone: stay calm so the patient stays calm. If you come at a victim screaming, their heart rate spikes, they bleed faster, and they panic. You have to be the "calm in the storm," even if you’re vibrating with adrenaline.

The Legal and Psychological Reality
Let’s talk about the "Good Samaritan" laws. People are terrified of getting sued. They think if they pull someone out of a car and the person ends up paralyzed, they’ll lose their house. In almost every jurisdiction in the U.S. and Canada, as long as you aren't acting with gross negligence (like trying to perform a roadside tracheotomy with a ballpoint pen), you are protected.
The law expects you to act as a "reasonably prudent person" would. Helping someone out of a smoking car is prudent. Dragging someone with a minor leg injury out of a stable car just because you're nervous is less so.
Why You Should Probably Leave Them in the Car
Unless the car is literally on fire or submerged in water, leave them in the vehicle. Modern cars are designed to be survival cells. The seats and frame provide a natural splint for the spine. When you pull someone out, their head flops. Their vertebrae shift. If there’s a fracture, you could sever the spinal cord.
Wait for the "Jaws of Life." Let the professionals with the neck collars and backboards do the heavy lifting. Your job is mostly "psychological first aid." Hold their hand. Talk to them. Tell them help is coming. Ask them their name. Keep them awake. Sometimes, just having a human connection is enough to keep someone from going into deep shock.
Communication With Dispatch
When you call 911, don't just ramble. Dispatchers need specific data.

"I’m at the intersection of 5th and Main. Two-car MVA. One person trapped. One person conscious but bleeding. Power lines are down."
That’s it. That’s the gold standard. They don't need to know the color of the cars or whose fault it was. They need to know how many ambulances and fire trucks to send. If you don't know your location, look for mile markers or use a "what3words" app if you have it. In 2026, most dispatch centers can geolocate your phone, but don't bet your life on it.
Dealing With the Aftermath
After the sirens arrive and the police start taking statements, you’re going to crash. The adrenaline dump is real. You might start shaking. You might feel like crying. This is a normal physiological response to trauma.
Upon arriving at the scene of a motor vehicle crash, you took on a burden most people avoid. It’s okay to talk to a professional about it later. Secondary PTSD isn't just for cops and medics; it's for anyone who stares into the maw of a tragedy and tries to help.
Actionable Steps for the Prepared Citizen
You shouldn't wait for an accident to happen to figure this out. Being a "good bystander" is a skill set. It requires a bit of prep and a lot of guts.
- Carry a basic trauma kit. Not a "first aid kit" with Disney Band-Aids. You need a CAT (Combat Application Tourniquet), QuikClot gauze, and a window punch. Keep it in your glove box, not the trunk. If you’re pinned, you need to reach it.
- Take a "Stop the Bleed" course. These are often free or very cheap. They teach you how to actually use a tourniquet and pack a wound. It’s the difference between watching someone die and keeping them alive until the helicopter arrives.
- Download offline maps. If you’re traveling through rural areas with spotty cell service, you need to know where the nearest hospital is without relying on a 5G signal that might not exist.
- Practice situational awareness. When you pull up, look for "hidden" victims. Sometimes people are thrown from the vehicle into the tall grass or woods. Check the back seats for car seats. A vacant car seat is a terrifying sight for a first responder; it means there might be a baby somewhere in the brush.
- Secure your own vehicle. Once you've stopped, make sure your car is in park and the emergency brake is on. People have been known to jump out of their cars in a panic, only to have their own vehicle roll into the crash scene.
The reality of being the first on the scene is that it’s messy, loud, and smells like burnt rubber and various fluids. It is never "clean." But if you can keep your head, manage the scene's safety, and provide basic life support until the pros arrive, you have fundamentally changed the outcome of someone's worst day. You don't need a cape. You just need to stay focused and keep the scene from getting worse.
Make sure you've checked your own vehicle's safety kit today. Ensure your fire extinguisher is charged and your tourniquet is accessible, not wrapped in plastic. Small steps in preparation make the massive difference between a witness and a lifesaver.
