You have exchanged details, the other driver has apologised, the tow truck has gone, and you feel shaken but basically fine. That is the normal experience of a crash, and it is one of the reasons people end up worse off than they needed to be.

What Adrenaline Is Doing

In the minutes after an impact your body is doing exactly what it evolved to do, which is suppress pain and keep you functional. That effect lasts for hours, sometimes into the next day. Soft-tissue injuries in the neck and back very often declare themselves the following morning, and a good deal of what people describe as sleeping badly after a crash is the injury arriving.

None of that means everyone who is shaken is hurt. It means feeling fine at the roadside is not evidence that you are uninjured, and it is the worst moment to make decisions about whether you were.

The Symptoms Worth Taking Seriously

These are the ones that commonly show up late and get dismissed:

  • Headache that will not settle, especially with light sensitivity or nausea.
  • Neck or shoulder stiffness that is worse on day two than day one.
  • Trouble concentrating, or losing the thread in conversations you would normally follow.
  • Sleeping badly, or far too much.
  • Being unusually short-tempered. This one is almost always attributed to stress, and it is a recognised sign of a head injury.
  • Numbness or tingling in an arm or hand.
  • Abdominal pain or bruising, which can indicate something that needs attention quickly.

The last of those is a same-day matter. Most of the rest are reasons to be seen within a day or two rather than to wait and see.

Why the Record Matters as Much as the Treatment

There is a practical reason to be examined early that has nothing to do with how you feel. If a claim follows, the first question asked of it will be whether the injury came from the crash. A medical record created two days afterwards answers that. A record created six weeks afterwards invites the argument that something else caused it, and that argument is made in nearly every file where the gap exists. We have written separately about how gaps in treatment are used against a claim.

This is not a reason to manufacture treatment you do not need. It is a reason not to tough out symptoms you actually have.

The One Thing Not to Sign

An adjuster may contact you quickly with an offer to settle, often a modest sum, often framed as covering the inconvenience. Accepting it generally means signing a release, and a release closes the claim for good, including for the injury you have not been diagnosed with yet.

That offer arrives before anybody, you included, knows what is wrong. It is worth an hour of someone's time before you sign anything. There is more on this in what to do after a car accident in Montana and in our note on how a demand letter works.

The Deadline Is Long. The Evidence Is Not.

The general limitation period for injury claims in Montana is 3 years under MCA § 27-2-204, and different deadlines can apply depending on the claim and who the defendant is. That sounds like plenty of time, and legally it often is. The useful evidence does not last nearly as long. Vehicles get repaired, footage is overwritten within days, and witnesses stop remembering the sequence.

If you are unsure whether you have a claim worth making, that is a normal thing to be unsure about and a short conversation usually settles it. Our personal injury page explains how we work, and there is no cost to ask. Call 406-830-3060.
