Minimum Speed Limit
There are times when a minimum speed is required, such as in some tunnels. These blue signs with white writing indicate that vehicles must maintain at least a minimum speed (in this case 30mph).
Once a minimum speed limit has ended, then a blue sign with the limit and a red line through it will be shown. The speed limit will then become either what is signposted, or that of the prevailing type of road, for example the open road speed limit.
