What must you remember when you see this traffic sign?

The traffic sign you're looking at indicates specific parking regulations. When you see this sign, it typically means that street lighting does not remain on all night, which is crucial for drivers to take into account. Additionally, this sign often serves as a reminder that vehicles should not be parked continuously in that area overnight without proper lighting, as it could pose safety risks.

It's important to understand that in the absence of street lighting, parked vehicles may not be visible, increasing the chances of accidents or parking violations. Therefore, adhering to these regulations is essential for maintaining safety and compliance on the road.
