Short Answer:
Car accident injuries can appear immediately or be delayed for hours, days, or even weeks after a crash. Soft-tissue injuries like whiplash often appear within 24–72 hours, while concussions or internal injuries may take several days to develop. Learn about protecting evidence here.
Example:
If you feel fine after a crash but develop neck pain two days later, it could be whiplash. Many soft-tissue injuries do not cause symptoms immediately because inflammation and adrenaline can delay pain.
