A vehicular data recording device enabling a driver to get to know more about his driving technique to improve it. Not only images from a monitoring camera when a shock is detected are simply recorded in a memory card, but also images from the monitoring camera when no shock is detected are always updated and recorded in an HDD successively. Accordingly, images from the monitoring camera in various situations not leading to an accident can be surely supplied to a driver. This prompts the driver to reflect the driving thereof based on the images from the monitoring camera in the various situations. This can allow the driver to figure out the driving skill thereof, and improve the driving skill.
