Security has been tightened throughout the country with officers and soldiers observed on patrol in major cities ahead of expected anti-government protests scheduled for independence day.
By midday, however, no demonstrations had begun.
Residents in Dar es Salaam, Arusha, Mbeya, Mwanza reported an unusually slow start to the day, with a large number opting to stay home amid uncertainty over if the demonstrations would proceed.
The demonstrations were called to demand political reforms in the wake of October's post-election unrest which left an unknown number of people dead.
Officials have conceded employing force against demonstrators, claiming that some groups were attempting to overthrow the regime.
Correspondents noted on Tuesday nearly empty streets in the business hub, Dar es Salaam. This stood in sharp contrast to the city's usual weekday bustle.
The quiet was undercut by a persistent sense of tension.
Armored vehicles were spotted cruising along major roads and intersections, while personnel were stationed at key points, particularly near key public infrastructure.
On social media, activists and campaigners urged supporters to stay alert, suggesting any demonstrations were unlikely to begin until the afternoon. The messaging echoed past mobilization efforts in the country, when turnout increased later in the day.
Drivers who went out experienced frequent checks at roadblocks, where police interrogated motorists about where they were headed.
The government has not issued specific statements on the heightened security measures or on the scheduled demonstrations.
The government has prohibited the planned protests and cancelled independence day celebrations, advising the public to remain at home.
"An eerie quiet masks the underlying tension felt by those indoors."
The day's events painted a picture of a nation on edge, where the potential for demonstration resulted in a preemptive security lockdown that left conspicuously quiet normally bustling cities.
