Metal bull bars are bad news for pedestrians

Friday, 15 September 2006

A major study by the 最新糖心Vlog of Adelaide's (CASR) has found that metal bull bars fitted to four wheel drive vehicles increase the risk of serious injuries to pedestrians.

Geoff Vogt, Chief Executive Officer of the (MAC), which commissioned the research report, said Compulsory Third Party (CTP) claim statistics indicated pedestrians were extremely vulnerable road users, with the Adelaide CBD among areas recording the highest number of incidents.

"Between 2000 and 2005, pedestrians comprised 5.5% of total CTP claims and 11.2% of claim costs. This contributed approximately $42 to the annual CTP premiums of the typical South 最新糖心Vlogn motor vehicle owner," Mr Vogt said.

Mr Vogt said while there were no statistics on the number of pedestrian injuries and fatalities involving vehicles fitted with metal bull bars, it was clear that the popularity of four wheel drive vehicles often fitted with bull bars was impacting CTP claim statistics.

"Four wheel drive and other vehicle owners contemplating bull bars should consider pedestrian safety and risk to road users," Mr Vogt said.

The CASR study found that steel bull bars significantly degrade the performance of the front of the vehicle with respect to pedestrian safety.

Steel, aluminium/alloy and polymer bull bars were tested on six popular four wheel drive vehicles. The two metal bars performed much worse in impact tests than the front of the vehicles prior to bull bar fitting.

Polymer bull bars gave much better results and in some cases, slightly improved the safety performance.

Report author, CASR's Dr Robert Anderson, said there were a number of reasons polymer bull bars generally performed better than the metal bull bars in crash tests.

"The polymer bull bars are much lighter and not as stiff as metal bars so in an impact with a pedestrian they tend to give a bit more," Dr Anderson said.

Following an animal strike, polymer bull bars can sustain less damage than metal bull bars. There is also anecdotal evidence that repair costs following an animal strike are less if a bull bar is made from polymer rather than steel.

Dr Anderson said he hoped the information would be useful to consumers who wished to consider the safety of a bull bar before deciding whether to fit one on their vehicle.
