What to Do in the First 72 Hours After a Car Accident

The most common thing we hear from car accident patients is some version of: I felt fine at the scene. That is not unusual. It is the norm. Adrenaline and the acute stress response suppress pain effectively for hours, and soft tissue inflammation takes time to build.

Which is why the first 72 hours matter so much. Here is what to do, in order.

At the scene

1. 1Call 911 and get a police report, even for a minor collision. A report is the single most valuable document in a disputed claim.
2. 2Photograph everything: all four corners of both vehicles, the license plates, the overall scene, road conditions, and any visible injuries.
3. 3Exchange insurance information and get the other driver's name, phone number, and policy number.
4. 4Get contact information from any witnesses. They disappear fast and are very hard to find later.
5. 5Do not say you are fine. Say you are not sure yet and you will be evaluated. It is honest and it protects you.

Within 24 hours

• Report the accident to your own insurance company, regardless of fault.
• Write down everything you remember while it is fresh: direction of travel, speed, weather, what you were doing, exactly how your body moved on impact.
• Start a symptom journal. Note pain, stiffness, headaches, dizziness, sleep quality, and anything that feels off, with dates and times.
• Go to an emergency room immediately if you have any red flag symptoms.

Within 72 hours: get properly evaluated

This is the step people skip, and it is the one that matters most for both your health and your claim.

On the health side: soft tissue injuries heal by laying down collagen, and left untreated that collagen forms in a disorganized, cross-linked pattern. That scar tissue is weaker, less elastic, and permanently restrictive. It is the mechanism by which a crash at 28 becomes chronic neck pain at 40. Early treatment influences how that tissue heals during the window when it is still possible to influence.

On the claim side: adjusters look hard at the gap between the collision date and the first date of treatment. A delay of several weeks gives them a defensible argument that your injuries came from something else. Prompt documented evaluation removes that argument entirely.

But my car was barely damaged

This is the most common reason people talk themselves out of getting checked, and the reasoning is backwards. Modern bumpers are engineered to absorb impact energy without visibly deforming. Energy that used to crumple sheet metal now transfers into the occupants instead.

Documented whiplash injuries occur regularly in collisions under 10 miles per hour. Your cervical spine does not know what your bumper looks like. It only knows your head was thrown forward and back faster than the ligaments could control.

Mistakes that damage your claim

• Giving a recorded statement to the other driver's insurer before you have been evaluated. You are not obligated to, and you cannot accurately describe injuries you do not know about yet.
• Accepting a fast settlement offer in the first week. Early offers are made precisely because the full extent of soft tissue injury is not yet apparent.
• Gaps in treatment. Starting care and then missing three weeks is read as evidence you recovered.
• Posting on social media. Photos of you at a game or on a trip will be used against your claim, regardless of how you actually felt that day.
• Waiting to see if it gets better. It is the single most expensive decision people make after a crash.

What evaluation should include

A proper post-accident exam is more than someone asking where it hurts. It should include orthopedic and neurological testing, measured range of motion, and imaging when indicated, digital X-ray to rule out fracture and to assess whether your cervical curve has been altered, which is an objective and measurable consequence of whiplash.

It should also produce documentation that will hold up: detailed, properly coded narrative reports that an adjuster or attorney can actually use. If findings suggest disc involvement or anything outside conservative scope, you should be referred for advanced imaging immediately rather than treated around.

We see auto accident patients on a same-week basis at our Frisco office, and most pay nothing out of pocket. If you were in a collision anywhere in Frisco, Plano, The Colony, Little Elm, or Lewisville, call (972) 433-7557.
