A motorist should know that he/she is entering a work zone because of diamond-shape, orange work zone signs, the presence of a "flagger," and a sign with a flashing arrow panel. These three signs alert drivers to the fact that they are entering a work zone, where workers are present and where there may be changes in the driving environment so the correct answer is option (D).
The diamond-shaped, orange work zone sign is a standard sign used to designate work zones and alert drivers to the fact that they are entering a construction area. The sign has a black legend and border on an orange background. The sign may include information on the nature of the work being done, such as "road work ahead" or "lane closed ahead."The presence of a flagger is another indication that a driver is entering a work zone. A flagger is a person who is stationed at a work zone to direct traffic, typically using hand signals or a flag. Flaggers are typically used in situations where traffic needs to be directed around a work zone, such as when lanes are closed or when there is a detour.A sign with a flashing arrow panel is a third way that a driver can be alerted to the presence of a work zone.
These signs are typically used in situations where there are lane closures or detours, and they provide drivers with information on the proper lane to use. The flashing arrow panel may also include information on the speed limit in the work zone, or other safety information that drivers need to be aware of.
