Hello; Bull bars are named kangaroo bars in Denmark and were mounted to trucks on Scandinavian routs to protect the vehicle at collisions with moose, bears or reindeers. Bull bars are made from a different profiles. Round, Rectangular, Square, Tapered box, and That weird profile that Volvo use. The are also made in steel and stainless steel, as well as printed plastic. Most truckies are regular folk and not some kind of heartless monster like the media would have us believe, and feel very bad when they run over animals. No one likes to see road full of road kill. but swerving to miss an animal is usually just not an option. Also it's often a bad ending for the truck as well and a large animal passing under your vehicle at speed often results in damage to steering, brake and electric lines, wheels and tires. It is commonly thought the a startled animal will naturally run for it's home when in danger which is why a lot of them will actually cross in front of you at very short notice. Often less than 3 meters.
