According to a study published in the journal Traffic Injury Prevention, bull bars "substantially modify the collision dynamics of automobiles, resulting in an elevated risk of pedestrian injury and fatalities in collisions."
The study also found that vehicles with bull bars had lower rates of survival after being involved in moderate-to-severe crashes. The researchers concluded that the added protection afforded by bull bars may be greater than expected from looking at them on the street. They also noted that because these bars reduce a vehicle's ability to deform in a crash, they could prevent important information about the severity of the accident from being transmitted to the driver.
In conclusion, the researchers wrote, "Because of their effect on automobile dynamics, we recommend against the use of bull-bars as a form of active or passive safety equipment."
Here are some other recommendations for safer car design:
Avoid fast roads and highways unless you need their extra space. They're more likely to have additional protective devices such as guard rails or noise-reducing walls.
Cars built since 1995 are required by law to have head-protecting air bags installed in both front seats. These bags can only be activated if neither person is wearing a seat belt, so they provide an important additional measure of safety for unbelted occupants.
This review of the literature demonstrates that bull bars do actually enhance the severity of injuries to vulnerable road users in the case of a collision, emphasizing the need for current traffic safety rules to reflect the safety issues surrounding the usage of bull bars. In addition, it appears that the use of bull bars may be associated with an increased risk of injury to other vehicle occupants.
Bull bars are added armor plating designed to protect vehicles from damage during collisions at low speeds. They are most commonly found on pick-up trucks and SUVs, but are also used on cars and motorcycles. The purpose of adding bull bars is to provide extra protection for drivers and passengers in cases of low-speed accidents. However, research has shown that they can increase the risk of injury to other people in a car crash.
In 2007, bar studies showed that vehicles with bull bars had higher risk scores than those without. This means that drivers of these vehicles were more likely to suffer serious injuries in a crash. One study conducted by the University of Michigan examined the effects of adding a bull bar to vehicles. It was found that drivers of these vehicles were 24 percent more likely to suffer severe injuries in a crash compared with drivers of similar models with no bull bars. The researchers concluded that the addition of bull bars may not only fail to protect drivers but could actually put them at greater risk of harm in a crash.
A bull bar adds weight to the front of the vehicle, which can lead to increased tire wear. A poorly constructed or incorrect bull bar might interfere with the deployment of airbags, lowering the vehicle's crashworthiness. Bull bars, according to research, can significantly increase pedestrian injuries.
The added weight at the front of the car increases the force of impact if there is a collision, which could cause other problems with your vehicle. For example, the increased weight at the front of the car will make it harder for the engine to turn over. If you have to push your car for many reasons (such as when you need to make room for emergency responders), a bull bar could prevent you from being able to do so effectively.
Bull bars were originally designed to protect the front end of vehicles that were being driven aggressively, such as off-road vehicles and sports cars. The heavy bar would act as protection for the driver's head in case of an accident. As technology has improved and cars have become more aerodynamic, the need for bull bars has decreased. However, they remain popular on trucks and SUVs because of their protective nature.
There are several different types of bull bars available today. Each one is used for different purposes. Some bars are made only of metal, while others may also include plastic or other materials.
In layman's words, the crumple zones considerably lessen the effect of energy and damage in the case of an accident, and the passengers within the car suffer less shock and injury. Installing bull bars not only affects the efficacy of crumple zones, but also poses a direct risk to an individual's safety. Drivers with no regard for personal safety have been known to remove them for "hot rod" looks.
Bull bars were originally designed to protect vehicle bodies from damage caused by collisions with other vehicles or with stationary objects. Today's bull-nosed cars often come with these protective devices because they help to prevent passengers from being seriously injured by being thrown against the side of the vehicle in an accident. The National Highway Traffic Safety Administration (NHTSA) has stated that vehicles with bull bars are 2.5 times more likely to be involved in accidents compared to similar vehicles without them. The agency also reported a significant increase in the number of accidents involving bull-nosed vehicles during its recent review of motor vehicle injuries.
The primary purpose of a crumple zone is to disperse impact energy across a large area through deformation and dissipate it as heat through friction. The more heavily a vehicle weighs, the more stress there is on the crumple zone. As long as the weight remains within the specifications set by law, then the vehicle is acceptable to travel on public roads.
