The Importance of the Subject The traffic accidents have become the top reasons of many deaths and injuries. The main reasons of such accidents are not only the neglect or non-observance of road rules but the non-observance of safety regulations. The most susceptible to the traffic accidents and injuries are motorcyclist as far as motorbike is quite a dangerous means of transport. The necessity to protect motorcyclists from probable accidents has necessitated this research. We are going to cast light upon the importance of the use of helmets by motorcyclists and passengers as far as brain injuries are the most serious ones and head injuries have irreparable consequences. The problem is that many motorcyclists as well as their passengers neglect the use of such preserver as helmet and sometimes have to pay for their light-mindedness with their life. The Factors Conditioned the Necessity of Adopting Helmet use Laws in all Countries This current issue of the necessity in the strict rules of using helmets and following these rules should be taken into account by the government of every country where this means of transport is quite popular, by official representatives who are responsible for the order on the road and by the motorcyclists, passengers. Motorcycles are more dangerous compared to other means of transport. According to the latest researches of the Insurance Institute for Highway Safety, the number of deaths on motorbikes in 2007 was 37 times per mile traveled ( Motorcycle Helmet Use Laws , 2012). There were 4, 281 deaths among motorcyclists and their passengers in 2009 more than in 1997 but less than in 2008 which hit the records in the number of motorbike fatalities which accounted into 5, 112.

Wearing helmet in this case is very important as well as other protective equipment. Helmets protect motorcyclists from head injuries which are so often caused by accidents on motorbikes. Head injuries are the leading cause of death among motorcyclists ( Motorcycle Helmet Use Laws , 2012). Many countries have strict rules committing the motorcyclists as well as their passengers to wear helmets. It should be noted, that not every country has such strict rules. Laws obligating all motorcyclists to use helmet are followed in 19 states and the District Columbia. Laws requiring only some categories of motorcyclists to wear helmet are adopted in 28 states (Barth, 2011). There is not any law requiring to wear helmet at all only in three states namely in Illinois, Iowa and New Hampshire. As for the USA, the history of the use of this law started in 1967. Michigan was the first state that began to realize the helmet use law in 1968. The use of this law continues to be followed in the USA ( Motorcycle and Bicycle Helmet use Laws, 2012).
