Abstract: An inventive traction device is provided for extricating mired vehicles from mud, snow or sand. The device is comprised of modules linked together to create a track upon which a mired vehicle drives over. The individual modules each have four walls forming a trough and a number of tire supports which rise up from the floor of the trough. The trough-like construction of the device helps prevent the device from becoming overloaded with mud deposited from mired vehicle tires.
