Based on both Pearson correlation and Canonical Correlation Analysis (CCA), the correlation of intrinsic motivation incentives with perceived benefits under the influence of respect for the law was statistically significant (χ2 = 68.751, P In this study, care for appearance is regarded as an intrinsic motivation which has a significant correlation in almost all psychological factors and finally leads to the use or not use of a helmet. Another key factor which persuades the riders to wear a helmet is respect to the traffic regulations; thus, enforcing the law may be a fundamental strategy for increasing helmet use.
