The report has pointed out the need to provide the truck driver with a semi trailer, the ability to see the contour of the semi trailer and road illumination in the insufficient lighting conditions. The need for equipping the vehicle with additional contour light and lamps illuminating the section of the road overrun by the semi trailer wheels has been assessed.

This is particularly important during manoeuvring with such truck – semi trailer unit at night to ensure safety, as the semi trailer has a different tracking circle than the towing truck. Current regulations are too (categorical) restrictive and limiting possibility of introducing additional lights. The proposal for technically solving this problem as well as amending the regulations, has been presented. The existing technical requirements included in current regulations on lighting do not take into account the need to ensure the visibility of these areas for the truck driver with a semi trailer.
