A synchronization device for synchronizing data associated with a vehicle test is presented. The synchronization device may include signal-generating circuitry configured to generate a signal and provide the signal to at least one output device associated with a vehicle so as to allow a data collection device to receive the signal from the at least one output device. The synchronization device may also include first additional circuitry configured to prevent the data collection device from receiving the signal based on whether a test associated with the vehicle has started. At least one of the providing of the signal to the at least one output device or the preventing of the data collection device from receiving the signal may indicate a start of the test and may allow data collected by the data collection device to be synchronized with other collected data.
