Hawaii Drivers Permit Practice Test

What does a sign that says "Slippery when wet" warn drivers about?

1. Watch for drunk drivers.

2. Dangerous curve.

3. Bump in road ahead.

4. Slippery when wet.

The correct answer is: Slippery when wet.

The sign that states "Slippery when wet" specifically warns drivers about the potential for reduced traction on the road surface when it rains or when the pavement is otherwise wet. This is particularly important for drivers to understand, as wet roads can increase the likelihood of losing control of the vehicle. The presence of this sign indicates that extra caution should be taken, such as reducing speed and maintaining a greater following distance, to ensure safety under such conditions. Other options mention different hazards, but they do not directly relate to the condition of the road when wet. For example, warnings about drunk drivers or bumps in the road concern different scenarios that do not specifically address the issues caused by wet road conditions. The focus of the "Slippery when wet" sign is to prepare drivers for the immediate danger presented by a lack of traction, thereby enhancing roadway safety during inclement weather.
