Look to your lawyer for help in answering a question. Try to memorize your story. Justice requires only that a witness tell the story to the best of his or her ability. Rehearsed stories often sound false. Smoke or chew gum.
Some people find it helpful to make lists to refresh their recollection or put dates in order.
Feel free to do so, but if you do, bring the lists with you to the deposition and give them to your lawyer before you begin. Remember, these lists are to help you and your lawyer, but you may not be able to refer to the lists or testify from them during your deposition. List all of your injuries from this accident, from the top of your head to your feet. Also list psychological trauma, headaches, sleep problems, fear of driving, etc. List all significant injuries, illnesses, and medical treatments you have had before and after this accident.
