Major highways in Kampala on Wednesday experienced heavy traffic after the government partially lifted lockdown measures that barred private transport.
Police said several people had been arrested and their cars impounded for violating the 7pm to 6.30am curfew rules.
According to directives issued last week by President Yoweri Museveni, private transport was allowed to resume from May 26 and to carry a maximum of three passengers.
Public transport will resume on June 2 with buses operating at half capacity to ensure physical distancing rules are adhered to.
"This opening of public transport will not be allowed in the border districts of Uganda for another 21 days.
