Abstract: A driving data recording device for vehicles includes a plurality of sensing units, a processing unit, a display unit and a wireless transceiving unit. The sensing units are configured to detect a plurality of driving parameters. The processing unit is electrically connected to the sensing units, and the driving parameters are transmitted to the processing unit and converted to driving data through the processing unit. The display unit is electrically connected to the processing unit. A display interface is generated on the display unit. The driving data are displayed through the display interface. The wireless transceiving unit is electrically connected to the processing unit and connected to a serving unit through a network. The driving data are immediately transmitted to the serving unit through the wireless transceiving unit.
