A sign displaying the location of scattered farms and homesteads in a rural area of Iceland. Road signs in Iceland are visual communication devices placed along roads and highways throughout the country to provide information, warnings, and guidance to motorists and pedestrians.
When an ice road is part of a winter road, as is commonly the case, its design and construction is comprised within the overall road planning, i.e. in conjunction with the over-land segments. [2] Either way, factors that need to be addressed before construction include the following:
Traffic signs or road signs are signs erected at the side of or above roads to give instructions or provide information to road users. The earliest signs were simple wooden or stone milestones . Later, signs with directional arms were introduced, for example the fingerposts in the United Kingdom and their wooden counterparts in Saxony .
These signs are often temporary in nature and used to indicate road work (construction), poor roads, or temporary conditions ahead on the road including flagmen, uneven pavement, etc. (Note that some "high water" signs are posted to alert drivers of a flood-prone area and do not actually mean that there is a flooded section of road ahead.)
