If your car accident caused injuries that made it difficult or impossible for you to work, you can recover damages for lost wages.   This includes both wages lost because you were unable to work and wages lost because you missed work while you were undergoing medical treatment. The term usually starts on the date of the accident and runs until you were able to return to work. Even if you were able to take sick or vacation pay for time missed from work, you’re still entitled to recover damages for that.   To prove a lost wages claim, you will need: A letter from your supervisor or boss including your name, position, number of hours you usually work, and the number of hours or days missed after the accident. Medical records showing the treatments you got and the time you needed for recovery. If you are self-employed, you’ll need to provide evidence that shows what you lost in terms of income. This may include documents that show a drop in billing or invoices, a calendar showing appointments that had to be canceled, or other documents showing projects you were unable to complete or conferences you were not able to attend.
