What should a driver be cautious of when a divided highway begins ahead?

• A. Increased speed restrictions
• B. Potential for merging traffic
• C. Reduced visibility
• D. Pedestrians on the road

Answer: (B)

Being cautious of potential for merging traffic when approaching a divided highway is important because divided highways often indicate a transition point where vehicles may be entering or exiting the roadway. This means that drivers should be attentive to vehicles that may be merging onto the highway, as well as those that might be leaving it. The divided nature of the highway provides some separation between traffic going in opposite directions, but it also signifies that vehicles may not be as predictable in their movements as they would be on a non-divided roadway. Therefore, staying alert for merging traffic helps ensure safety by allowing drivers to adjust their speed and position accordingly to accommodate other vehicles.

While factors like increased speed restrictions or reduced visibility may also be relevant in some driving scenarios, they do not specifically correlate with the unique characteristics of divided highways as closely as the merging aspect does. Pedestrians are typically not found on highways, so that consideration is less applicable in this context.
