Many people collect evidence in drunk driving cases, including: Police officers. Emergency medical technicians. Accident witnesses. Your medical providers, including those in the emergency room. Investigators who work for insurance companies, the police, and/or your attorney. Law firms. Those who collect evidence – except for law firms – collect it to investigate a crime, monitor traffic flows, and provide medical attention. However, your drunk driving accident lawyer can also use this evidence to help prove your case. You should allow the professionals to collect this type of evidence. You can, however, help your case by collecting specific evidence without contaminating the accident scene. For example, if you are able, you might take pictures of the accident. Do not worry about it if you cannot; the police will take photos. Additionally, you may receive or already have documents and other physical evidence that might help your case. As soon as you retain a drunk driving accident lawyer, you should turn that evidence over to the firm. Your priority is ensuring you are safe. If it is too dangerous to take pictures of the accident scene because of traffic, for example, do not do it. Also, if the police are looking over the accident scene, let them do their jobs. Interfering by getting in the way so you can take pictures could distract them from gathering evidence that could help your case. It could also contaminate evidence that might support your case.
