What must you do when you see a "road closed" sign?

When you encounter a "road closed" sign, the crucial action is to not proceed past the sign and to find an alternate route. This sign indicates that the road is not safe for travel, potentially due to construction, damage, or other hazards that could pose risks to your safety and the safety of others.

Ignoring the sign could lead you into dangerous situations, such as encountering obstacles or other hazards that are not visible until it's too late. Additionally, proceeding past the sign could interfere with road work or emergency services addressing the situation, potentially causing further delays or accidents.

Finding an alternate route shows adherence to traffic regulations and concern for safety on the road. It is always important to respect traffic signage, as they are there to protect both drivers and pedestrians.
