A vehicle event data playback apparatus comprising one or more processors configured to synchronize vehicle operation information, wherein synchronizing the vehicle operation information comprises: receiving the vehicle operation information via output signals generated by sensors coupled with a vehicle, the sensors including a first sensor that generates a first output signal conveying information related to a first operating parameter, and a second sensor that generates a second output signal conveying information related to a second operating parameter, wherein the first output signal includes first timing information, and wherein the second output signal includes second timing information; detecting a first vehicle event based on the first output signal and the second output signal, the first vehicle event having a start time and an end time; responsive to detecting the first vehicle event: associating information from the first output signal and the second output signal generated during the first vehicle event to create a first event record, wherein the first timing information indicates the start time of the first vehicle event, wherein the second timing information indicates the start time of the first vehicle event, and wherein the first timing information may not coincide with the second timing information; and synchronizing the information from the first output signal and the second output signal generated during the first vehicle event, wherein synchronizing includes: determining that the information conveyed by the first output signal indicates the start of the first vehicle event, associating said information with the start time of the first vehicle event, searching the information conveyed by the second output signal that indicates the start time of the first vehicle event, regardless of any timing information included in the second output signal, and subsequent to finding the information conveyed by the second output signal that indicates the start of the first vehicle event, associating the found information with the start time of the first vehicle event. receiving the vehicle operation information via output signals generated by sensors coupled with a vehicle, the sensors including a first sensor that generates a first output signal conveying information related to a first operating parameter, and a second sensor that generates a second output signal conveying information related to a second operating parameter, wherein the first output signal includes first timing information, and wherein the second output signal includes second timing information; detecting a first vehicle event based on the first output signal and the second output signal, the first vehicle event having a start time and an end time; associating information from the first output signal and the second output signal generated during the first vehicle event to create a first event record, wherein the first timing information indicates the start time of the first vehicle event, wherein the second timing information indicates the start time of the first vehicle event, and wherein the first timing information may not coincide with the second timing information; and synchronizing the information from the first output signal and the second output signal generated during the first vehicle event, wherein synchronizing includes: determining that the information conveyed by the first output signal indicates the start of the first vehicle event, associating said information with the start time of the first vehicle event, searching the information conveyed by the second output signal that indicates the start time of the first vehicle event, regardless of any timing information included in the second output signal, and subsequent to finding the information conveyed by the second output signal that indicates the start of the first vehicle event, associating the found information with the start time of the first vehicle event. determining that the information conveyed by the first output signal indicates the start of the first vehicle event, associating said information with the start time of the first vehicle event, searching the information conveyed by the second output signal that indicates the start time of the first vehicle event, regardless of any timing information included in the second output signal, and subsequent to finding the information conveyed by the second output signal that indicates the start of the first vehicle event, associating the found information with the start time of the first vehicle event.
