Below are several example entries a the .list file.

Break up your travels by highway and region. By region, we usually mean a country, such as Spain or Germany. However, for large countries like the United States and Canada, further break your travels down by state or province as well. Then use the Highway Browser to look up the highway and waypoint labels.

• Highway segment within a single region.
  For the segment of I-80 between Exits 161 and 224 in Pennsylvania, look up the highway and waypoint labels for those interchanges in the Highway Browser. The Browser shows the highway as PA I-80 and lists the waypoints as 161 and 224. Enter the following line into your .list file:
  
  PA I-80 161 224
  
  
• Highway segment crossing into multiple regions.
  To enter the segment of I-81 between Exit 300 in Virginia and Exit 10 in New York, break up the segment into smaller pieces by region. The Virginia segment begins at Exit 300 and ends at the West Virginia border, so use waypoints 300 and VA/WV for the Virginia segment. I-81 runs from border to border in West Virginia, Maryland, and Pennsylvania, so use waypoints WV/MD, MD/PA, and PA/NY for these states. The New York segment begins at the Pennsylvania border and ends at Exit 10, so use waypoints PA/NY and 10. Enter the following lines in your .list file for this whole segment:
  
  VA I-81 300 VA/WV
  WV I-81 VA/WV WV/MD
  MD I-81 WV/MD MD/PA
  PA I-81 MD/PA PA/NY
  NY I-81 PA/NY 10
  
  
• Beltways (full loop highways) within a single region.
  Single-region beltways are treated as a highway beginning and ending at the same reset point after looping around a city. For example, the Baltimore Beltway (Maryland I-695) resets at the southern point labeled as both 0 and 48. If the segment you wish to enter crosses that point, split your segment into two at that point.
  
  Consider first the segment of the Baltimore Beltway (I-695) between exits 17 and 31 along the northern side of Baltimore. Since the waypoints run continuously from 17 to 31 without resetting (compare to next example), treat this segment simply as beginning at Exit 17 and ending at Exit 31:
  
  MD I-695 17 31
  
  Now consider the southern segment of the Baltimore Beltway between the same Exits 17 and 31. The waypoints numbers reset in this range: 17, 16, ..., 1, 0, 48, 44, ..., 31. Waypoints 0 and 48 refer to the same point. With this in mind, treat your whole segment as two, one with ends at 0 and 17, and the other with ends at 31 and 48:
  
  MD I-695 0 17
  MD I-695 31 48
  
  To enter the entire Baltimore Beltway, use the two labels for the reset point:
  
  MD I-695 0 48
  
  
• Beltways crossing into multiple regions.
  Treat segments along these beltways just as you would any other segment that crosses into multiple regions: one .list file line per region.
  
  
• Overlapping highways (multiplexes).
  Highways can overlap another highway so that the same highway has two or more concurrent numbers. Include separate lines in your .list file for each highway in overlaps.
  
  For example, if you travelled all of I-84 in Pennsylvania, you also traveled on an overlapping piece of I-380. Include a line for each highway:
  
  PA I-84 0 PA/NY
  PA I-380 I-81 24
