You may drive across a dashed white line:
At any time.
Only during daylight hours.
When it is safe to change lanes.
Only when passing a motorcycle.
The Correct Answer and Explanation is :
The correct answer is: When it is safe to change lanes.
Explanation:
A dashed white line on the road indicates that lane changes are permitted. It is used to separate lanes of traffic moving in the same direction. This type of line signals that drivers are allowed to move from one lane to another, provided that the maneuver is safe and does not pose a risk to other road users.
In many countries and regions, traffic laws and road markings help ensure the safe and efficient flow of traffic. A dashed white line specifically provides drivers with the flexibility to change lanes, unlike a solid white line, which indicates that lane changes are discouraged or prohibited. The key condition for crossing a dashed white line is that it must be done safely. This means drivers need to check for any oncoming traffic, blind spots, and ensure that there is adequate space in the adjacent lane before making a move.
It’s essential to understand that while you can cross a dashed white line, it is your responsibility to do so in a manner that does not endanger yourself or others. This requires good judgment, timely signaling, and awareness of other road users’ actions. For instance, you should not change lanes if it would interfere with another vehicle or put you in an unsafe position, such as when approaching an intersection, curve, or in heavy traffic conditions.
The other choices provided—at any time, only during daylight hours, and only when passing a motorcycle—are not correct because they do not accurately reflect the purpose of a dashed white line. Lane changes are not restricted to daylight hours nor limited to when passing specific vehicles like motorcycles. Drivers should always prioritize safety when deciding to change lanes, regardless of the time of day or type of vehicle nearby.
