5 RDING TRI MNGMNT DIGRM (TMD) Usually contractors place the signs on one side of the road with the TMD the right way up. When signs are placed for the other side of the road the contractor tips the TMD upside down and reads which signs have to be placed for that side of the road. To make this process easier: Signs going up the page are shown closest to the road Signs going down the page are shown further away from the road Sign icons and sign numbers for layout down the road (from top to bottom of the TMD) are turned upside down.
