A6 highway (Lithuania)
The speed limit for most of the length of A6 is default 90 km/h (outside city limits). The section from Kaunas to Jonava has been upgraded to a dual carriageway with at-grade junctions and traffic-lights. The remaining sections are roads with one lane in each direction, leading through towns like Ukmergė, Utena and Zarasai.
Autobahn
The Federal Road Research Institute ("Bundesanstalt für Straßenwesen") solicited information about speed regulations on autobahns from the sixteen States and reported the following, comparing the years 2006 and 2008:
Except at construction sites, the general speed limits, where they apply, are usually between and ; construction sites usually have a speed limit of but the limit may be as low as . In rare cases, sections may have limits of , or on one ramp . Certain stretches have lower speed limits during wet weather. Some areas have a speed limit of in order to reduce noise pollution during overnight hours (usually 10pm – 6am) or because of increased traffic during daytime (6am – 8pm).
Some limits were imposed to reduce pollution and noise. Limits can also be temporarily put into place through dynamic traffic guidance systems that display the according message. More than half of the total length of the German autobahn network has no speed limit, about one third has a permanent limit, and the remaining parts have a temporary or conditional limit.
