Just a quick question, Is there a legal or required amount of speed signage on country roads .. Say for example a road of approx 7 km's in length between two towns , as you are approx half a km from exiting one town there is a sign post that reads 80 km , you leave said town and are now out on a country road , with no housing or street lighting , and not one speed sign until you have travelled approx 7 km's and there is now an entry speed sign of 60kms into the next town . Is the road you have been travelling on a 80km zone ?? Or is it a 100km zone ??
