The Correct Answer and Explanation is :
The correct answer is: Drivers may pass if it is safe to do so.
Explanation:
A single dashed white line separating traffic is a common road marking found on roads where traffic moves in the same direction. This type of line indicates that lane changes are permitted, but only when it is safe to do so. Drivers should always check their surroundings, use their mirrors, and signal their intentions before changing lanes to ensure that it does not pose a hazard to other road users.
Why Drivers May Pass:
This marking is designed to facilitate traffic flow. It allows vehicles to overtake slower-moving traffic or switch lanes as needed to reach their destinations. However, the ability to pass is conditional: safety takes priority over convenience. Drivers must consider the visibility, road conditions, and the behavior of other vehicles before deciding to maneuver.
Common Situations:
- Highway Driving: On multi-lane highways, dashed white lines separate lanes of traffic going in the same direction. They indicate that vehicles can move between lanes to adjust for speed or prepare for upcoming exits.
- Merging Areas: In areas where lanes merge or diverge, dashed white lines guide the merging process, signaling drivers to enter or exit a lane when it is safe.
Risks and Responsibilities:
Passing without due caution can lead to accidents. Drivers must ensure:
- There’s sufficient space: Sudden moves in tight traffic could result in collisions.
- No blind spots: Other vehicles or motorcyclists could be obscured.
- Weather conditions: Rain, fog, or poor lighting may reduce visibility.
Understanding this rule is critical for safe driving and helps prevent traffic incidents, ensuring all road users share the road responsibly. Always prioritize safety over haste when deciding to pass.
