Drone video taken over Beirut showed the Lebanese capital, known for its traffic jams, relatively empty on Tuesday after the government told people not to leave their houses except for shopping and emergencies.
Some cars were still visible but most streets were entirely deserted after police started fining people who were found walking on the seaside promenade.
Lebanon has been under a lockdown for more than week to stop the spread of the new virus.
The number of infected people in the country stood at 304, with four deaths.
Most patients who contract the new coronavirus develop only mild symptoms and recover after about two weeks.
But the virus is highly contagious and can be spread by those with no visible symptoms.
For older adults and people with underlying health problems, it can cause more severe illness, including pneumonia.
