When driving on a multi-lane roadway toward an active construction zone, a driver notices an electronic arrow board mounted on a stationary service vehicle displaying four flashing corner lights in a caution pattern rather than a directional arrow. What action should the driver take in response to this display?
- Proceed through the area with heightened caution within the current lane while adjusting speed for work zone conditions.Cevap
- BExecute an immediate lane change away from the vehicle regardless of traffic conditions in adjacent lanes.
- CMaintain the standard posted highway speed limit because no explicit directional merge signal is shown.
- DBring the vehicle to a full stop directly in front of the arrow board until a flagger provides manual hand signals.
Cevap
The driver should proceed through the area with heightened caution within the current lane while adjusting speed for work zone conditions.
Four flashing corner lights on an electronic arrow panel signify caution mode. This warns drivers of nearby construction or maintenance activities on or adjacent to the roadway, requiring increased awareness and speed control while staying in the current lane unless a lane shift is explicitly marked by channelizing devices.
