TRUM Vol 3 has been renamed and new content added. Now titled Signing and Pavement Marking, two new Parts have been added to this Volume:
- Part 5: Design Guide for Roadside Signs and
- Part 6: State Strategic Touring Routes Sign Revitalisation.
Titles and dates of other Parts have been updated but content otherwise remains unchanged.
Details of all changes are recorded in the TRUM Amendment Register.
