California MUTCD <br /> (FHWA's MUTCD 2003 Revision 1,as amended for use in California) Page 6H-28 <br /> Notes for Figure 614 40 6H-10(CA)—Typical Application 10 ' <br /> Lane Closure on Two-Lane Road Using Flaggers <br /> Option: <br /> 1. For low-volume situations with short work zones on straight roadways where the flagger is visible to <br /> road users approaching from both directions, a single flagger,positioned to be visible to road users <br /> 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. A BE <br /> PREPARED TO STOP sign may be added to the sign series. <br /> Guidance: <br /> 4. The buffer space should be extended so that the two-way traffic taper is placed before a horizontal(or <br /> crest vertical)curve to provide adequate sight distance for the flagger and a queue of stopped <br /> vehicles. <br /> Standard: <br /> 5.At night,flagger stations shall be illuminated,except in emergencies. <br /> Guidance: <br /> 6. When used, the BE PREPARED TO STOP sign should be located between after the Flagger sign and <br /> the ONE LANE ROAD sign. I <br /> 7. When a highway-rail grade crossing exists within or upstream of the transition area and it is <br /> anticipated that queues resulting from the lane closure might extend through the highway-rail grade <br /> crossing,the TTC zone should be extended so that the transition area precedes the highway-rail grade <br /> crossing. <br /> S. When a highway-rail grade crossing equipped with active warning devices exists within the activity <br /> area,provisions should be made for keeping flaggers informed as to the activation status of these <br /> warning devices. <br /> 9. When a highway-rail',grade crossing exists within the activity area, drivers operating on the left side of <br /> the normal centerline should be provided with comparable warning devices as for drivers operating on <br /> the right side of the normal centerline. <br /> 10. Early coordination with the railroad company should occur before work starts. <br /> Option: <br /> 11. A flagger or a uniformed law enforcement officer may be used at the highway-rail grade crossing to <br /> minimize the probability that vehicles are stopped within 4.6 in(15 ft)of the highway-rail grade <br /> crossing, measured from both sides of the outside rails. <br /> Support: <br /> 12.
