Final answer:
White lane arrows indicate the direction of traffic flow, with curved arrows directing drivers to bend in the direction of the arrow and straight arrows implying a continuation of forward movement. These markers are essential for guiding drivers safely.
Step-by-step explanation:
When you see white lane arrows that are curved or straight on a roadway, they are directing the flow of traffic. Curved arrows indicate that drivers are to follow a path that bends in the direction of the arrow, typically suggesting a change in direction such as a turn or merge. Conversely, straight arrows suggest that drivers should continue moving forward, maintaining their current lane. These road markings are crucial for guiding drivers and keeping traffic organized and safe.
For example, the presence of curved arrows on the roadway would imply an approach to a roundabout require motorists to follow a circular path around a central island before exiting onto their desired roadway. Straight arrows would be seen in lanes that are meant to cross an intersection or continue forward at a junction. Paying attention to these markers is important for maintaining an orderly traffic flow and preventing accidents.
