The study examined the relationship between movement control restrictions, standard operating procedures and business uncertainty of public transport operators in Kampala. Specific objectives of the study were; assess the relationship between movement control restrictions and business uncertainty; standard operating procedures and business uncertainty; and examine combined effect of movement control restrictions and standard operating procedures on business uncertainty of public transport operators in Kampala. This was a cross-sectional research design with a quantitative research approach. A sample of 92 public transport operators was used. This involved public transport operators selected from 6 taxi parks in Kampala. Data was collected using a structured questionnaire. The study used SPSS (v.25) to analyze data and interpreted results using a frequency table and inferential statistics. Findings established positive relationship between movement control restrictions and business uncertainty; positive relationship between standard operating procedures and business uncertainty among public transport operators in Kampala (r=.646, p<.01); and found that movement control restrictions and standard operating procedures significantly predict business uncertainty among public transport operators in Kampala. The main predictor of business uncertainty was movement control restrictions. The study concludes that while interventions undertaken by the government of Uganda to deal with COVID19 have proved crucial in achieving this objective, they have extremely affected the business environment. Movement control restrictions and standard operation procedures are increasing business uncertainty of public transport operators in Kampala. The study recommends government to relax movement control research.miu.ac.ug/publications 355 METROPOLITAN JOURNAL OF SOCIAL AND EDUCATIONAL RESEARCH ISSN: 1813-4270 Vol. 2 Issue 4, July - 2023, Pages: 355-369 restrictions; and encourage public transport operators should consider further increment of transport fares
