Summary
This study addresses the persistent safety issue of drivers illegally passing stopped school buses, a behavior that has resulted in significant fatalities and injuries over decades. Despite the severe consequences, little research had previously investigated whether a lack of legal knowledge contributes to these violations. The National Highway Traffic Safety Administration (NHTSA) commissioned this national survey to assess driver knowledge of school bus passing laws, identify specific knowledge gaps, and inform the development of targeted countermeasures. The researchers conducted an online survey using a nationally representative sample of 3,557 drivers recruited from NORC’s AmeriSpeak panel. Participants were screened to ensure they were 18 or older and drove at least occasionally. The survey utilized 3-D animations to present seven distinct scenarios involving stopped school buses with various signal configurations (e.g., red lights, stop-arms, yellow lights) and roadway types (e.g., two-lane undivided, four-lane divided). Drivers were asked to identify the legal requirement for each scenario, with correct answers determined by the participant’s state of residence. The survey also assessed awareness of enforcement mechanisms, penalties, and opinions on prevention strategies. Results indicated that while the majority of drivers correctly identified the requirement to stop when approaching or overtaking a bus on two-lane undivided roads (over 90% correct), knowledge dropped significantly in more complex scenarios. Only 55.5% of drivers knew the correct action when approaching a bus on a four-lane undivided road, and just 17.8% knew the requirement when approaching on a four-lane divided road. Knowledge was also low for buses in line at schools (27.2%). Furthermore, nearly three-quarters of participants were unsure of the penalties for illegal passing, and 58.2% were uncertain about the permissibility of enforcement cameras in their area. When asked about the causes of illegal passing, 24.3% of respondents attributed it to drivers not knowing the law. The study concludes that significant gaps in driver knowledge exist, particularly regarding multi-lane roadways and varying state laws, which likely contribute to the high frequency of illegal passes. The findings suggest that countermeasures should focus on clarifying these ambiguous legal requirements and increasing awareness of enforcement tools. Public opinion strongly supports camera enforcement (24.7%) and stricter penalties (21.0%), with nearly 70% of drivers agreeing to ticketing the registered vehicle owner rather than the driver, offering a viable enforcement strategy that bypasses the difficulty of identifying the specific driver.
Key finding
While most drivers know they must stop for school buses on two-lane undivided roads, knowledge drops significantly for four-lane road scenarios, and most drivers are unaware of enforcement cameras and penalties.
