Yellow lines separate:
Traffic lanes on one-way streets.
Traffic moving in opposite directions on two-way roads.
All carpool lanes from regular traffic lanes.
The Correct Answer and Explanation is :
The correct answer is: Traffic moving in opposite directions on two-way roads.
Explanation:
Yellow lines are used to indicate the division between lanes in traffic, and their color and pattern convey specific meanings related to road safety and traffic flow.
- Traffic lanes on one-way streets: This statement is incorrect. On one-way streets, white lines are typically used to separate traffic lanes. Yellow lines are reserved for marking divisions on two-way roads where vehicles travel in opposite directions.
- Traffic moving in opposite directions on two-way roads: This is the correct answer. Yellow lines are used on two-way roads to separate traffic traveling in opposite directions. A solid yellow line indicates that passing is not allowed, while a dashed yellow line allows for passing when it’s safe. The yellow lines on these roads provide a clear visual cue to drivers that they should remain in their lane and avoid crossing into the path of oncoming vehicles, which helps prevent accidents.
- All carpool lanes from regular traffic lanes: This statement is incorrect. Carpool lanes, or HOV (High Occupancy Vehicle) lanes, are typically marked with white lines or other specific signs, not yellow lines. Yellow lines generally don’t separate carpool lanes unless those lanes are also part of a two-way road with traffic moving in opposite directions.
The use of yellow lines for dividing lanes on two-way streets is crucial for road safety. It ensures that drivers are aware of the direction of traffic flow on either side of the line and helps prevent collisions. In addition to the visual guidance, yellow lines also play a role in enforcing traffic rules, such as prohibiting overtaking or passing in certain areas. These guidelines are particularly vital on roads without physical barriers separating traffic.
