Most people’s shock fades in the weeks after a crash. When it doesn’t, here’s what to know.
Normal reactions to a frightening event
Shakiness, trouble sleeping, replaying the crash and feeling on edge are normal in the days and weeks after a collision. For most people, these reactions ease over time.
When it might be more
Post-traumatic stress disorder (PTSD) can develop when symptoms last longer than a month and get in the way of daily life. Symptoms usually fall into four groups:
- Re-living it: intrusive memories, nightmares, or feeling as if it’s happening again.
- Avoiding reminders: the car, the route, or conversations about the crash.
- Changes in mood and thinking: guilt, blame, numbness, or losing interest in things you enjoyed.
- Feeling on alert: jumpiness, irritability, and trouble concentrating or sleeping.
Only a qualified professional can make a diagnosis, but you don’t need one to ask for help.
Effective treatment exists
Trauma-focused therapies, including trauma-focused cognitive behavioural therapy, are among the most effective treatments for PTSD. They help you process the memory safely, so it feels like something that happened rather than something still happening.
Things that help in the meantime
- Keep a regular time to sleep and wake up
- Go easy on alcohol and cannabis, which can worsen sleep and mood
- Stay connected with people you trust
- Move your body, even gently
- Notice what you’re avoiding, and take small steps back toward your routines
Getting care through your insurer
Psychological injuries after a collision can be covered through auto insurance once a treatment plan is approved. From January 1, 2027, Care-First benefits include mental health conditions related to the collision.

Questions
Quick answers.
Can PTSD start months later?
Yes. Sometimes symptoms appear or get worse weeks or months after the event. It’s still worth getting help.
Will I have to talk about the crash in detail?
Not right away. Your therapist starts with safety and coping skills, and you decide the pace.
