During the summer, when driving conditions are generally better, the maximum speed on some parts of the country's major roads is temporarily increased to 100 or 110 km/h. However, the arrival of autumnal conditions sees those sections revert to the 90 km/h limit for the autumn and winter seasons.
State roads agency Latvijas valsts ceļi said: "Though the first decade of October has been dry and sunny, one must count on the changeable autumn weather conditions, when the surface of the roads can be wet and icy, especially in the morning hours when the temperature drops below zero. In these conditions an especially dangerous invisible layer of ice can form, also called black ice. It is most frequently formed on bridges, overpasses, roads near forests and water bodies."
If you discover difficult driving conditions or a blocked road you can report it to Latvijas Valsts ceļi by calling the 24-hour toll-free information line 80005555.
A map with information on driving conditions on the state road network is available on the LVC website which is updated every two hours or more often if driving conditions change dramatically. This information is also displayed in the Waze navigation application.
