Perspectives on Different Interlocks and Reminders to Promote Seat Belt Utilization among ASEAN Drivers

Abstract

This study examines drivers' views on various interlocks and seat belt reminders, intending to increase compliance and awareness in the ASEAN New Car Assessment Programme (NCAP). Questionnaires were distributed to a total of 1394 drivers from Malaysia (n=502), Indonesia (n=505), and Thailand (n=387). In total, five different extreme interlocks and six types of reminders were proposed, and the respondents' responses were analyzed. Key findings showed that Malaysians favored the interlock that prevents a vehicle from exceeding 25 km/h (32.5%), while Indonesians (49.1%) and Thais (36.4%) preferred the interlock that prevents the car from starting (switching on). Regarding the seat belt reminders, all three countries (Malaysia, Indonesia, and Thailand) agree (43.4%, 37.2%, and 30.7%) that a buzzer or chime is the most effective seat belt reminder to use in vehicles. This study highlights the importance of customized strategies to improve seat belt use, offering insights for policymakers and automotive manufacturers to address safety challenges specific to ASEAN drivers.
