Make an outline that includes a table of contents and brief summaries for each section you'd like to include in the book. Sections might include: "What to Do Immediately Following a Car Accident;" "How to Settle a Property Damage Claim with the Insurance Company;" and "How to Document Medical Treatment and Expenses."
Gather together helpful documents or web links that you would like to include in the final product. A good auto accident book will provide the reader with access to information and materials they might need. Examples include: a form letter they can customize and send to the insurance company regarding opening a claim or an Internet link that will assist them in evaluating loss value due to damage to the vehicle.
Write the major sections of the book first. These sections will contain the bulk of the helpful material, so it's best to get them flushed out fully before working to connect the sections into a cohesive book. Remember to break up copy: short paragraphs of 50 to 75 words or less work well.
Be specific and direct. Tell people what to do and expect in simple, step-by-step language. Use your personal knowledge of everything that can happen after the car accident up until the time a case is settled and closed.
Write an introduction and brief connecting passages between the sections of the book. Insert graphics (pictures, charts, documents) where appropriate as they assist the reader in absorbing the content more fully.
Print the book and have a professional editor proofread it and make suggestions. Incorporate these suggestions as you prepare a final copy. Once the content is perfect, you can format the book and turn it into an eBook and/or a bound physical book. For the second choice, you will need to take the copy to a printer for binding.
