Introduction: As transportation network companies (TNC) are on the rise, assessing the safety of children traveling in these vehicles is imperative. For this reason, this study developed and adopted a scoring system to assess states’ safety standards for children traveling in TNC vehicles. Methods: The scoring was based on two parameters pertaining to child car seat laws for TNCs: clarity and stringency. For each parameter, three criteria that could impact child safety in TNC vehicles were formulated. If a state met a certain criterion it got 1 point and 0 otherwise. The authors gathered all the necessary information by reviewing state statutes in Nexus Uni, a legal research database. These reviews took place between December 2019 and October 2020, and this study evaluated state laws in effect on October 28, 2020. Results: During this assessment, the authors observed a lack of clarity in state child car seat laws, which could compromise safety of children traveling in TNC vehicles. For clarity of laws, Georgia and Indiana received the highest scores (3 out of 3 points), while 16 states scored only 1 point, which was the lowest score in this category. In terms of stringency of laws, Pennsylvania received the highest score (3 out of 3 points), while Indiana scored the least (0 points). Conclusions: Besides one state (Oregon), all other states defined TNCs in their state laws. All states except for Indiana and Washington required child car seats in TNC vehicles. The responsibility for child car seat use was clearly defined in 35 states. The fine for child car seat violation was $50 or more in 28 states. Practical Application: This study will help TNCs, policymakers, and stakeholders identify states that need to improve their standards for child safety in TNC vehicles, and comprehensively address the issue.

简介：随着交通网络公司 (TNC) 的兴起，评估乘坐这些车辆的儿童的安全性势在必行。出于这个原因，本研究开发并采用了一个评分系统来评估各州对乘坐 TNC 车辆的儿童的安全标准。方法：评分基于与跨国公司儿童汽车座椅法有关的两个参数：清晰度和严格性。对于每个参数，制定了可能影响 TNC 车辆中儿童安全的三个标准。如果一个状态满足某个标准，它就得 1 分，否则得 0 分。作者通过查阅法律研究数据库 Nexus Uni 中的州法规收集了所有必要的信息。这些审查发生在 2019 年 12 月至 2020 年 10 月之间，本研究评估了 2020 年 10 月 28 日生效的州法律。结果：在这次评估中，作者发现各州儿童汽车安全座椅法律缺乏明确性，这可能会危及乘坐 TNC 车辆的儿童的安全。为清楚起见，乔治亚州和印第安纳州得分最高（3 分中的 3 分），而 16 个州仅得 1 分，是该类别中的最低分。在法律严格程度方面，宾夕法尼亚州得分最高（3 分中的 3 分），而印第安纳州得分最低（0 分）。结论：除了一个州（俄勒冈州）外，所有其他州都在其州法律中定义了跨国公司。除印第安纳州和华盛顿州外，所有州都要求 TNC 车辆配备儿童汽车安全座椅。35 个州明确规定了使用儿童汽车安全座椅的责任。在 28 个州，违反儿童汽车安全座椅的罚款为 50 美元或更多。实际应用：本研究将帮助跨国公司、政策制定者和利益相关者确定需要提高跨国公司车辆儿童安全标准的州，并全面解决该问题。
