Rideshare services provided by companies like Uber and Lyft have become much more popular in recent years. In Q4 2021, Uber reported an average of 19.5 million trips a day worldwide, and Lyft reported 18.7 million active riders (defined as riders who take at least one trip during the quarter). As personal vehicles become less desirable and common among urban residents, rideshare and taxi services will likely continue to become more popular.

Unfortunately, growing evidence suggests that use of child restraint systems (CRS) in rideshare and taxi vehicles is much lower than usage rates in personal vehicles. Since CRS are a crucial tool in decreasing the risk of crash injury for children, this research aimed to ensure that advances in personal mobility in the U.S. are not accompanied by setbacks in child safety.

The objective of this research was to develop guidance to identify and prioritize the types of behavioral interventions needed to improve child passenger (defined as children under 13 years of age) safety in the for-hire ride share environment, including taxis.
