| Refer to this chart to determine the road type of a given road based on the functional class. (TXDOT map is [http://www.txdot.gov/apps/statewide_mapping/StatewidePlanningMap.html here] - click on ''Functional Class'' on the left).
| |
| | |
| To use this chart, first determine the functional class of a road, and whether it is a signed, numbered highway in a particular highway system.
| |
| | |
| Where the column for the road's highway system and the row for the road's functional class meet, you will find the proper road type for that particular road.
| |
| | |
| A number of examples are given below the chart.
