Kecelakaan lalu lintas merupakan salah satu permasalahan serius di Indonesia, terutama yang melibatkan pengendara sepeda motor. Berdasarkan data IRSMS Korlantas Polri tahun 2024, sekitar 73% kecelakaan lalu lintas melibatkan kendaraan roda dua dengan 60% korban merupakan pengendara sepeda motor. Tingginya penggunaan sepeda motor turut meningkatkan pelanggaran lalu lintas, termasuk oleh pengendara anak di bawah umur. Penelitian ini bertujuan menganalisis jenis pelanggaran lalu lintas pengendara sepeda motor berdasarkan kategori usia serta mengetahui pengaruh usia terhadap jenis dan tingkat risiko pelanggaran. Penelitian dilakukan melalui observasi langsung di Jalan Syiah Kuala dan Jalan Pocut Baren–Jalan Gabus selama tiga hari pengamatan dengan lima sesi waktu setiap harinya. Data dianalisis menggunakan statistik deskriptif kuantitatif, uji chi-square, dan odds ratio. Hasil penelitian menunjukkan bahwa sepeda motor mendominasi volume lalu lintas dengan persentase lebih dari 73% dari total kendaraan. Pelanggaran yang paling dominan adalah tidak menggunakan helm dengan persentase tertinggi mencapai 43,43% pada pengendara anak di bawah umur dan 43,09% pada pengendara dewasa. Uji chi-square menunjukkan adanya hubungan signifikan antara kategori usia dengan pelanggaran tidak menggunakan helm dan melawan arus, dengan nilai chi-square tertinggi sebesar 7,39. Selain itu, seluruh nilai odds ratio berada di atas 1 dengan nilai tertinggi sebesar 2,32, yang menunjukkan bahwa pengendara anak di bawah umur memiliki risiko pelanggaran lebih tinggi dibandingkan pengendara dewasa. Temuan ini menunjukkan bahwa kategori usia berpengaruh terhadap kecenderungan pelanggaran lalu lintas, khususnya pada pengendara anak di bawah umur.

Traffic accidents remain a major public safety issue in Indonesia, particularly those involving motorcycle riders. According to the 2024 IRSMS data issued by the Indonesian National Police Traffic Corps, approximately 73% of traffic accidents involved two-wheeled vehicles, with motorcycle riders accounting for 60% of the victims. The increasing use of motorcycles has also contributed to a rise in traffic violations, including violations committed by underage riders. This study aims to analyze the types of traffic violations among motorcycle riders across different age categories and to examine the influence of age on the types and risk levels of traffic violations. The study employed a direct observational method conducted on Syiah Kuala Road and Pocut Baren–Gabus Road over a period of three observation days, with five observation sessions carried out each day. Data were analyzed using quantitative descriptive statistics, chi-square analysis, and odds ratio (OR) analysis. The findings revealed that motorcycles dominated the traffic volume, accounting for more than 73% of the total observed vehicles. The most prevalent violation was failure to wear a helmet, with the highest percentages recorded among underage riders (43.43%) and adult riders (43.09%). Chi-square analysis demonstrated a significant association between age category and violations related to helmet use and riding against traffic flow, with the highest chi-square value reaching 7.39. Furthermore, all odds ratio values exceeded 1, with the highest OR value of 2.32, indicating that underage riders were more likely to commit traffic violations compared to adult riders. These findings suggest that age category significantly influences traffic violation tendencies, particularly among underage motorcycle riders. Therefore, stricter traffic law enforcement and preventive educational measures targeting underage riders are necessary to improve road safety and reduce traffic violations.
