What is the purpose of warning signs on the road?

The purpose of warning signs on the road is to inform drivers about road conditions and alerts. These signs are designed to enhance safety by warning drivers of potential hazards ahead, such as sharp turns, changes in road conditions, pedestrian crossings, or intersections. By conveying important information, warning signs help drivers prepare and respond appropriately, thereby reducing the risk of accidents.

Each type of road sign serves a specific function, with warning signs focusing on alerting drivers to situations that may require extra caution. For instance, if a sign indicates a slippery road ahead, it prompts drivers to slow down and drive more cautiously. This proactive approach to safety is essential for maintaining effective control of vehicles on the road.

The other options address different types of road signs: regulatory signs manage traffic speed and rules, directional signs guide drivers to various routes, and parking zone signs indicate where parking is permitted or prohibited. These serve important roles but are distinct from the primary function of warning signs in alerting drivers to potential dangers.
