The Motorcycle Rider Behavirour Questionnaire (MRBQ) in relation to on-road crash risks and traffic offences in Vietnam

In this paper, the factor structure of the Motorcycle Rider Behavior Questionnaire
(MRBQ) is investigated in Vietnam, a developing country with an extensive motorcycling
culture. Furthermore, we examine the predictive validity of MRBQ factors, riding information
and demographic variables in terms of self-reported near-crashes, crashes, and traffic
violations of riders. Exploratory factor analysis of MRBQ (N = 2.254 riders) was performed
and revealed a clear four-factor structure of 36 items. The results raise some critical differences
between motorists from Vietnam and other countries. Vietnamese riders without a valid license
have a lower on-road crash/near-crash rates, and the use of safety equipment paradoxically
increased the incidence of crash risks. Furthermore, crash/near-crash liability and offences of
Vietnamese riders increased with riding years. Overall, this study gives some further knowledge
about the current traffic situations in Vietnam. Besides, the 36-items version of the MRBQ has
been explored and could be replicated to investigate riding behaviours in other motorcycling
countries. Based on the robust relationships between MRBQ factors and accident risks, new
effective on-road safety campaigns can be developed to focus on reducing specific deviant
riding behaviours such as traffic errors, speeding and alcohol-related violations in Vietnam.
