Abstract
INTRODUCTION: Vehicle submersions account for up to 10% of all drownings in high-income countries. Reports indicate that occupants may be conscious and functional, but possibly making incorrect decisions for self-rescue leading to drowning. This study investigated current public knowledge, attitudes and practices regarding vehicle submersion incidents and to determine if individuals, who are aware of educational efforts regarding vehicle submersions, indicated better responses.Entities:

Fig. 2Panoramic view of vehicle side and front windows; front headrests were removed for clarity. Respondents selected which side window they would exit from, and then pointed to the specific location they would hit in order to break it (n = 82). Frequency is indicated within each window-area section (e.g., 4 corners and the center)
