Three series of impact tests were performed to study the behavior of lighting columns (sideways-on or head-on) impacts by private cars. The resistance met with by the vehicle in hitting a column, the denting of the passenger compartment, the location of the column after the impact and the influence of the electric current during the impact were investigated. It was found that a car meets little resistance from the column if the shaft of the column is easily separated from the roof section at about ground level. This could be achieved with special safety-designed columns or the use of aluminum columns. The height of the slip construction above ground level should be less than 10 cm. Ten metric aluminum columns with a base diameter/wall thickness of 175/4 mm will satisfy the ASI criterion for car occupants without seat belts in a head-on collision provided that such columns are not filled with sand. In sideways-on collision, these columns cause a combined vehicle deceleration about equal to or greater than unity. The polyester column offered too much resistance to the impacting vehicle. Further findings with regard to denting of the flank and roof of the car, the positions of the columns after impact, the danger in a 220 V electricity supply, and conclusions regarding car occupants not wearing seat belts are detailed.
