Abstract
A method and apparatus for monitoring towed vehicles, such as trailers and the like, which are not visible in a rear view mirror of a tow vehicle. The method consists of, firstly, attaching markers to a towed vehicle such that the markers are visible on each side of a towing vehicle to which the towed vehicle is coupled. Secondly, projections are attached to each side of the towing vehicle. The projections are positioned on each side of the towing vehicle so that the projections are in respective linear alignment with the markers when viewed from respective side mounted rear view mirrors of the towing vehicle. When the markers cease to be in linear alignment with the projections during driving, the driver of the towing vehicle is alerted that there has been an alteration in the positioning of the towed vehicle relative to the towing vehicle, thereby indicating a problem requiring a stoppage of the vehicles. <IMAGE>
