California MUTCD 2014 Edition Page 1157 <br />(FHWA's MUTCD 2009 Edition, including Revisions 1 & 2, as amended for use in California) <br />Notes for Figure 614 40 6 -10 CA and 6 -10A CA —Typical Application 10 <br />Lane Closure on a Two -Lane Road Using Flaggers <br />Option: <br />1. For low-volume (Refer to Part 5, Section 5A.01) situations with short work zones on straight roadways <br />where the flagger is visible to road users approaching from both directions, a single flagger, positioned to be <br />visible to road users approaching from both directions, may be used (see Chapter 6E). <br />2. The ROAD WORK AHEAD and the END ROAD WORK signs may be omitted for short -duration <br />operations. <br />3. Flashing warning lights and/or flags may be used to call attention to the advance warning signs. <br />A BE PREPARED TO STOP sign may be added to the sign series. <br />Guidance: <br />The buffer space should be extended so that the two-way traffic taper is placed before a horizontal (or crest <br />vertical) curve to provide adequate sight distance for the flagger and a queue of stopped vehicles. <br />Standard: <br />5. At night, flagger stations shall be illuminated, except in emergencies. <br />Guidance: <br />6. hen used, the B PR PAR D T ST P sign should be located b,.,,,r Rafter the Flagger sign and the <br />A R AD sign. <br />hen a grade crossing exists within or upstream of the transition area and it is anticipated that queues <br />resulting from the lane closure might extend through the grade crossing, the TTC zone should be extended <br />so that the transition area precedes the grade crossing. <br />hen a grade crossing equipped with active warning devices exists within the activity area, provisions <br />should be made for keeping flaggers informed as to the activation status of these warning devices. <br />hen a grade crossing exists within the activity area, drivers operating on the left-hand side of the normal <br />center line should be provided with comparable warning devices as for drivers operating on the right-hand <br />side of the normal center line. <br />10. arly coordination with the railroad company or light rail transit agency should occur before work starts. <br />Option: <br />11. A flagger or a uniformed law enforcement officer may be used at the grade crossing to minimize the <br />probability that vehicles are stopped within 15 feet of the grade crossing, measured from both sides of the <br />outside rails. <br />Support: <br />12. or State highways, see Caltrans' Standard Plan T13. See Section 1A.11 for information regarding this publication. <br />13. If portable transverse rumble strips are used for flagging operations, refer to Section 6 .87. <br />Chapter 611 — Typical Applications November 7, 2014 <br />Part 6 —Temporary Traffic Control <br />
