Head injuries due to motorcycle accidents are the main cause of death and disability among motorcycle users in Thailand. It is well known that wearing a helmet is one of the most effective ways to reduce the severity of head injuries due to motorcycle crashes. Although the helmet act for motorcyclists was enacted in Thailand in 1994, the rate of helmet use has not increased, and the rate of head injuries and fatalities due to motorcycle accidents has not been reduced. In this study, a field survey was conducted to observe helmet use in Bangkok and three other major regional provinces. The observation shows that the rate of helmet use is significantly low across the study areas. Age, location, time of day, and seating position significantly affect helmet use, whereas gender and the day of the week do not show any effect. The logit model was also used to evaluate the factors affecting helmet use on the basis of the injury surveillance data of motorcycle accident victims. Results indicate that the victims in the pillion, or passenger, position are less likely to use a helmet and those who ride during the nighttime, regardless of seating position, tend not to wear a helmet. To evaluate the effectiveness of helmet use and other related ways to reduce the severity of head injuries, the ordered logit regression technique was applied to the hospital-based data, using the data on patients suffering from head injuries due to road crashes. It is found that helmet use can reduce the severity of head injuries for motorcycle crash victims. The probability of fatality due to head injuries is reduced by 38% for motorcyclists wearing helmets. For motorcycle riders, helmets are found to be effective in protecting against head injuries, particularly for those riding under the influence of alcohol; the probability of death could be reduced by 43%. Those in the passenger position without helmets are more likely to sustain either serious or fatal head injuries than are riders without helmets. Results also indicate that a 58% reduction in the probability of fatality from head injuries is associated with the use of helmets by motorcycle passengers.
