Road safety enforcement in Papua New Guinea (PNG) plays a critical role in reducing traffic accidents and protecting lives. The country has established key road safety rules, including speed limits, mandatory seatbelt use, proper vehicle registration and valid driver licensing. These regulations are designed to promote responsible driving and ensure that vehicles on the road are safe and roadworthy. However, enforcing these rules consistently remains a challenge. 

According to local media reports, enforcement of road safety laws in PNG is often hindered by resource constraints and public noncompliance. Authorities have highlighted issues such as insufficient manpower, lack of equipment and challenges in monitoring remote areas, which contribute to ongoing traffic violations and accidents. These reports emphasise the need for stronger enforcement and increased public education to improve overall road safety outcomes. 

The establishment of road traffic rules in Papua New Guinea dates back to the colonial period, when early administrations introduced basic regulations to manage the small but growing number of motor vehicles. As the vehicle population expanded, the laws evolved to place greater emphasis on roadworthiness and public safety. The role of the Road Traffic Authority (RTA) became central in ensuring that vehicles meet minimum safety standards before being allowed on the road. This includes inspections for mechanical condition, proper documentation and compliance with safety requirements such as brakes, lights and tyres. Despite these improvements, challenges remain in consistently enforcing roadworthiness standards, underscoring the ongoing need to strengthen systems and raise awareness of vehicle safety in PNG.

The Royal Papua New Guinea Constabulary is primarily responsible for enforcing road safety laws. Police officers conduct regular roadblocks, inspect drivers’ licences and issue fines for traffic offences. Their presence is essential in deterring reckless driving and ensuring that motorists follow established rules. Despite their efforts, limitations such as staffing shortages and logistical challenges can reduce their effectiveness, particularly in rural and hard-to-reach areas.

The RTA complements police efforts by overseeing vehicle registration, driver licensing and roadworthiness inspections. Together, the Police and RTA collaborate through joint operations to strengthen compliance. Improving coordination, increasing resources and educating the public remain key steps toward safer roads in PNG.
