Eyewitnesses are bystanders who are at the scene at the time of the accident. It could be a pedestrian, bicyclist or other motorist, a customer standing outside of a business located where the crash happened, or anyone else was there at the time. If the person was involved in the accident though, they might not be able to provide an objective, third-party statement. This also applies if the eyewitness is related to the accident survivor or the at-fault party, the testimony might be valuable in some respect, but the credibility could be called into question.
