Hospitals in the capital Sofia and the Black Sea city of Varna said they had treated dozens of accident victims with fractures and other injuries. Mayors across the country appealed to people to stay at home.
Police closed stretches of the main international highways linking Bulgaria to neighbouring Romania and Turkey and urged drivers to avoid unnecessary travel while authorities struggled to free roads of ice by covering them with salt and sand.
Traffic was completely halted in the southern region of Stara Zagora, where police registered 25 road accidents in one hour, officials said. No traffic deaths were reported, according to the Ministry for Emergency Situations.
In Sofia, home to some 2 million people, dozens of public bus lines were shut down.
Temperatures rose to minus 3-4 Celsius (minus 27-25 Fahrenheit) after plunging as low as minus 21 C in some part of the country earlier this week, covering roads with a thick layer of ice.
