Commercial motorcycle services remain an important source of transportation and employment in the state; however, their largely informal and weekly regulated operations have raised serious security concerns. This study examined the relationship between lack of regulation of commercial motorcycle services and crime rate in Benue State, Nigeria, with emphasis on public perception and the challenges faced by government agencies in regulating the sector. A descriptive survey design was adopted, and data were collected from 400 respondents selected from members of the public, officials of commercial motorcyclists and police officers using structured questionnaire. Descriptive statistical tools such as frequency counts and percentages were used for data analysis. The findings revealed that the majority of respondents perceived a strong relationship between lack of regulation and control of commercial motorcycle services and increased crime rate. Key factors identified include anonymity of riders, absence of proper registration and identification, weak enforcement of operational guidelines, and poor monitoring, which enable the use of motorcycles in crimes such as robbery, theft, and kidnapping. The study also found that government agencies face significant challenges in regulating the sector, including inadequate manpower and logistics, corruption among enforcement officials, political interference, and resistance from motorcycle operators and unions, and high levels of unemployment and poverty. The study concludes that crime associated with commercial motorcycle services in Benue State is largely a consequence of weak regulatory and institutional frameworks rather than the transport system itself and recommends comprehensive regulation, compulsory registration and identification of operators, strengthened enforcement capacity, stakeholder collaboration, and socio-economic interventions to reduce youth unemployment.
