The well-understood risk to pedestrians posed by use of standard motor vehicles (which is managed by urban speed limits and other traffic-calming techniques) is herein compared with the increased risk that could be expected by postulating a hypothetical bull-bar attached to vehicles driven in urban areas. Recent data published by the University of Adelaide Road Accident Research Unit has enabled the incidence of vehicle-pedestrian collisions in a typical Australian urban environment to be quantified for various speeds. Hence the expected effects of the hypothetical bull-bar may be calculated and compared with actual cases involving bull-bars which were reported in the Adelaide data. It is shown that bull-bars reduce the mean impact speed for fatal collisions and hence, by inference, deaths (and serious injuries) tend to be increased. Prima facie, bull-bars contravene the mandatory Australian Design Rules (in particular ADR 42) which apply to most vehicles on the roads today and hence are illegal under federal, state and territory laws.
