The 2000 Helmet Use Survey reveals differences in use rates between vehicle types. While the use rates for both motorcycle and moped populations have decreased this year, the bicycle helmet use rate has increased. Further investigation is needed to understand the reasons for consistently higher bicycle helmet use rates in Hawaii county. A study examining the reasons for the low helmet use rate among moped riders needs to be conducted. Low helmet use among moped riders, for example, may be associated with the rider characteristics of those who operate mopeds.
Further study is necessary to determine if such a relationship exists.
If one looks at the low helmet use rate by moped riders in comparison with bicyclists and motorcyclists, it can be hypothesized that the difference in rates are a result of greater public awareness about helmet use as it pertains to bicyclists and motorcyclists.
