What does a white reflector (cat's eye) on the road mean?

A white reflector, commonly known as a cat's eye, on the road signifies the centre line. This type of road marker is used to help drivers identify the separation between lanes of traffic moving in opposite directions. By reflecting light back towards oncoming traffic, these reflectors enhance visibility during night-time or adverse weather conditions, allowing drivers to maintain their lane and avoid collisions. The presence of these reflectors is crucial for safe navigation, particularly on winding or poorly lit roads, as they guide drivers in orienting themselves relative to the road's layout.
