Answer :
A diamond-shaped, yellow road sign with two arrows pointing in opposite directions indicates 'Two-Way Traffic Ahead,' which is essential for driver safety and relates to traffic engineering efforts to optimize traffic light timing. So, option b is correct.
A road sign with a diamond shape, a yellow background, and two arrows pointing in opposite directions indicates 'Two-Way Traffic Ahead.' This sign is used to alert drivers that they are approaching an area where the road will be shared with oncoming traffic, usually in situations where the road has been a one-way or there has been some form of separation such as a median strip. Understanding this sign is important for driver safety, especially when considering situations related to student question six, where traffic engineers work on optimizing the yellow light duration to minimize the 'no-win' zone at intersections. The no-win zone is determined by factors such as the speed limit, visibility, and braking capabilities, which are important considerations when approaching any area with changing traffic conditions.
Final answer:
A diamond-shaped road sign with a yellow background and two arrows pointing in opposite directions warns drivers about upcoming two-way traffic. The drivers should slow down and be cautious.
Explanation:
A road sign with a diamond shape, a yellow background, and two arrows pointing in opposite directions signals Two-Way Traffic Ahead. This sign is typically placed ahead of sections of road where traffic lanes are about to change from one-way to two-way, indicating to drivers that they will soon encounter vehicles coming from the opposite direction. The use of such signs is common in urban areas and intersections where unexpected changes in traffic flow may occur. As a driver, it's important to decrease speed and increase alertness when this sign is spotted to avoid potential collisions.
