Vehicle seatbelt has been shown to have a beneficial impact on occupants. However, some occupants do not use the seatbelt when inside a moving vehicle. Despite the numerous investigation on the risk factors associated with seatbelt use by occupants, little is known about the relationship between driver and passenger seatbelt use. This gap is analyzed with road side observational survey data on driver and front-right seat passenger's seatbelt use behaviour using bivariate probit model. The use of the bivariate probit model is based on the premise that the front-right passenger's seatbelt use is endogenously related to that of the driver. Out of the 5,433 vehicles observed, the prevalence rate of driver and front-right passengers' seatbelt use were 81% and 33%, respectively. In addition, there is a positive relationship between driver and passenger's seatbelt use with correlation coefficient of 0.53. Thus, the unobserved factors that influence the probability of a driver seatbelt use also influence their front-right passenger's seatbelt use propensity.
车辆安全带已被证明对驾乘人员有有益影响。然而，一些驾乘人员在车辆行驶时不使用安全带。尽管对与驾乘人员使用安全带相关的风险因素进行了大量调查，但对于驾驶员和乘客使用安全带之间的关系却知之甚少。利用路边观察调查数据，通过双变量概率模型分析了驾驶员和副驾驶乘客使用安全带行为之间的这种差距。双变量概率模型的使用基于这样一个前提，即副驾驶乘客使用安全带与驾驶员使用安全带存在内生关系。在观察到的5433辆车中，驾驶员和副驾驶乘客使用安全带的普及率分别为81%和33%。此外，驾驶员和乘客使用安全带之间存在正相关关系，相关系数为0.53。因此，影响驾驶员使用安全带概率的未观察到的因素也会影响其副驾驶乘客使用安全带的倾向。
