Section 6F.17 - Position of Advance Warning Signs
Current through Register Vol. 28, No. 3, September 1, 2024
Guidance:
01 Where highway conditions permit, warning signs should be placed in advance of the TTC zone at varying distances depending on roadway type, condition, and posted speed. Table 6C-1 contains information regarding the spacing of advance warning signs. Where a series of two or more advance warning signs is used, the closest sign to the TTC zone should be placed approximately 100 feet for low-speed urban streets to 1,000 feet or more for freeways and expressways.
02 Where multiple advance warning signs are needed on the approach to a TTC zone, the ROAD WORK AHEAD (W20-1) sign should be the first advance warning sign encountered by road users.
Support:
03 Various conditions, such as limited sight distance or obstructions that might require a driver to reduce speed or stop, might require additional advance warning signs.
Option:
04 As an alternative to a specific distance on advance warning signs, the word AHEAD may be used.
Support:
05 At TTC zones on lightly-traveled roads, all of the advance warning signs prescribed for major construction might not be needed.
Option:
06 Utility work, maintenance, or minor construction can occur within the TTC zone limits of a major construction project, and additional warning signs may be needed.
Guidance:
07 Utility, maintenance, and minor construction signing and TTC should be coordinated with appropriate authorities so that road users are not confused or misled by the additional TTC devices.
