Activity after a crash
Movement or Rest After a Car Accident? Start With What Was Injured
For ordinary low back pain without significant trauma, prolonged bed rest is generally not recommended. A car accident is different because the first job is deciding whether the crash produced an injury that needs medical evaluation or specific restrictions.
If symptoms are severe, rapidly worsening, or you have an emergency warning sign after a crash, call 911 or go to an emergency department. Some symptoms after a head or body jolt can appear hours or days later. Review the warning signs after a car accident if you are unsure what deserves emergency care.

Ordinary Back-Pain Advice Is Not Crash Clearance
MedlinePlus and clinical guidelines support staying reasonably active for many routine episodes of low back pain rather than spending days in bed. That does not mean every person who was just in a collision should test the same advice on themselves.
Read MedlinePlus on back pain.
Read the American College of Physicians low-back-pain guideline.
A guideline for routine back pain does not rule out concussion, fracture, internal injury, or another trauma-related problem. Those questions come first.
If You Were Given Restrictions, Follow Them
If an emergency department, physician, or other clinician told you to avoid a particular activity, use a support, limit work, or return for follow-up, those instructions outrank general internet advice.
Do not use pain tolerance as a substitute for medical clearance after significant trauma.
Once Urgent Concerns Are Addressed, Avoid the All-or-Nothing Trap
When a clinician has not restricted activity and no emergency warning sign is present, the practical goal is often to avoid two extremes: forcing painful movement to prove you can do it, or becoming completely inactive because every movement feels uncertain.
Comfortable ordinary movement may be reasonable. The amount depends on the symptoms, the injury, and the advice you were given. If movement creates a new neurological symptom, severe worsening, dizziness, or another concerning change, stop using a general article as your guide and get medical advice.
Use Function, Not a Workout, as the Question
You do not need to turn recovery into an exercise challenge. Notice whether ordinary tasks such as walking, getting dressed, sitting, standing, or turning your head are gradually becoming easier or harder.
That information is useful at follow-up because it describes function without requiring you to diagnose the tissue yourself.
When a Musculoskeletal Evaluation May Help
If urgent concerns have been addressed and neck or back stiffness or soreness is still limiting normal activity, an evaluation may help determine whether conservative musculoskeletal care fits and what level of activity is reasonable for that complaint.
