After a fall, a bump at a stop sign, or a crash on the highway, most people remember the moment itself in pieces. The ride home is often where the details blur first. Who was in the car, whether anyone talked to you, what the radio was doing, and how long the trip took can all slip away by the next morning. Those small facts can help an examiner understand what your head was doing in the hours after the impact.
What to write down before you forget
Keep a few lines on paper or in a phone note. Start with the basics: the time you left the scene, the time you got home, and who drove. If someone else drove, note whether they said anything about how you looked or how you answered their questions. Write down whether you sat upright or reclined, and whether you had to turn to check traffic or look over your shoulder. Jot down the road type, such as surface streets, a highway, or a gravel shortcut, since speed changes and bumps can matter to how your neck and head felt.
Then note the trip itself. Did the light, the traffic, or the engine noise seem harder to handle than usual? Did you feel sick in the car, or did you need the window cracked or the seat moved? Did you close your eyes to get through it? These are not diagnoses. They are observations that help you describe the ride later in plain words.
Who was with you
A passenger or friend can be a useful witness, but only if you ask them to write down what they saw. Ask them to note whether you spoke clearly, whether you repeated questions, and whether you seemed unsteady when you got out of the car. Keep the request short. Ask them to send it to you by message the same day, with the time on it. A message written that evening is easier to rely on than a memory pieced together two weeks later.
If you were alone, write down what you remember, and add one line naming who could check on you over the next few days. Having that name ready makes it easier to answer later questions about who has been watching you.
Bring the note with you
Print the note or keep it on your phone, and bring it to your visit. Examiners often ask about the order of events, and a clear timeline helps. Mention the ride home in your first conversation rather than as an afterthought. Include the things you could not do during the trip, such as reading a street sign or remembering the route. Include the things that felt fine, too. A balanced account is more useful than a list of complaints.
If you are in the St. Louis metro, the same note works whether your appointment is downtown or out in the county. Bring a copy for yourself, since you may want to compare it with how you feel in the days that follow.
Keep the note simple. A single page is enough. Dates, times, the name of the driver, and a few plain sentences will do. Avoid guessing at causes. Write what happened and how it felt, and leave the interpretation to the people trained to read it.
Your examiner decides what the note means. Your job is to make it easy to read.
