A work zone is being set up near a curve where sight distance is limited. How should the advance warning signs be adjusted?
Answer: Move advance warning signs farther upstream to compensate for reduced sight distance
When sight distance is limited by curves or hills, advance warning signs must be placed farther upstream to give drivers adequate reaction time.
During the setup of a nighttime lane closure, which additional measure is required beyond standard daytime requirements in California?
Answer: All channelizing devices must have retroreflective sheeting or lights
At night, all channelizing devices must be retroreflective or have lights attached so drivers can see the work zone boundary.
When does a flagger's responsibility for the setup area officially end at the conclusion of a work day?
Answer: After all traffic control devices have been properly removed or secured for overnight use
The flagger's area responsibility ends when all devices are properly removed or secured, ensuring the roadway is safe for overnight traffic.
On a multilane highway, a flagger is helping set up a right-lane closure. Where should the first cone of the taper be placed?
Answer: At the point where the closed lane begins to narrow, farthest upstream in the taper
The first cone of the taper is placed at the upstream point where vehicles begin to be channelized laterally, farthest from the work space.
What is the primary hazard during the takedown of a temporary traffic control zone compared to setup?
Answer: Devices must be removed while traffic is moving at full speed through the now-open area
During takedown, as devices are removed, traffic begins accelerating back to full speed, increasing the risk to workers still in the area.
A flagger is setting up a work zone and notices the pre-positioned advance warning signs are facing the wrong direction. What is the correct action?
Answer: Stop setup and correct the signs before continuing
Signs facing the wrong direction provide no warning to drivers; they must be corrected before setup continues to ensure driver safety.
Which California document provides the standard plans and specifications for temporary traffic control setup used on state highway projects?
Answer: California MUTCD (Manual on Uniform Traffic Control Devices)
The California MUTCD provides the standardized guidance for all temporary traffic control devices and setups on California roadways.
