A: You will need to talk with your attorney about your best options. Not all intersections have cameras. Sometimes car accidents are he-said/she-said. There are ways for the Court to order an inspection of evidence as part of the discovery process. You would need to talk with your attorney about the best strategy in obtaining or not obtaining this evidence. Keep in mind that, although related, the ticket (criminal/traffic) case is separate from the civil (car accident damages) case and have different laws that apply.
A: If you purchased a vehicle that you at least knew had a salvage title, you would have known that some major repairs had to have been done on the vehicle in order to make it operational again after a total loss. You will want to review your purchase agreement in detail. If the vehicle was purchased as is and without any warranties, the seller may not have any duties to compensate you if the vehicle is no longer working. The laws in this area are more "buyer-beware" than consumer-friendly. You would need to review your documents and specific circumstances with an attorney to see what the best options are in your situation. Especially if the seller is a bigger deal and reputable, they may try to work with you even if the contract itself doesn't require them to.
A: The US Small Business Association might be a good place for you to start. The website of the Nebraska District Office of the SBA has tools to help small business owners get answers to their questions. For example, it looks like there is a seminar today in Lincoln, Nebraska about What's Involved in Starting a Small Business. Once you have more info, you can start making decisions about what type of legal entity to choose, which will affect how you pay taxes. You may also want to consult with a CPA and an attorney about forming your business but the SBA's website and information might be a good place for you to start. Good luck on your new journey.
