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.
Road speed limits in the United Kingdom
Rarely, minimum speed limits are used, such as through the Mersey Tunnels, to maintain free flow and safe passage through otherwise hazardous or enclosed areas. Circular blue signs with white numbers indicate the start of these limits, and similar signs with a red diagonal line indicate their end. Contrary to popular belief, there is no minimum speed limit on motorways, although certain classes of slow vehicles (as well as those of any class that cannot maintain 25 mph on the level whilst unladen) are prohibited on safety grounds and drivers are expected to not cause unnecessary obstruction by driving unusually slowly.
