13. For a stationary operation, maximum distance is 1000'. For a moving operation, maximum distance is 3000'.
12. Sign G20-55-96 is not required if this standard is part of other traffic control layouts or the work is less than 15 days.
11. As an option use portable sign supports in lieu of post mounted signs in accordance with NDDOT Standard Specifications.
B.21 30 mph, install a second speed limit sign with the desired speed reduction (not to exceed 30 mph.) Place the second speed limit sign at
10. Determine the reduced speed limit dependent on the in place speed limit before construction. Where speed limits are to be reduced more than
of the diamond sign, and at such a distance above the edge that the flag does not touch the sign when limp.
9. Install flags on warning signs in urban areas when signs are not portable. Mount 24 inch square flags perpendicular to the edges
8. Cover existing speed limit signs within a reduced speed zone.
7. Re-establish the speed limit. Determine the exact speed limit in the field, dependent on location and conditions.
Use Type C on roadways with high traffic speeds and volumes (over 40 mph or over 5000 ADT).
Use Type B on roadways with moderate traffic speeds and volumes (40 mph or less and 5000 ADT or less).
Use Type A on roadways with slow moving traffic speeds and low volume (25 mph or less and 750 ADT or less).
