What should you do if you encounter a yellow sign indicating road conditions are slippery?

Answer: C — Drive carefully and slow down

When you encounter a yellow sign indicating slippery road conditions, driving carefully and slowing down is essential for safety. This type of warning sign usually signifies that the road may be wet, icy, or covered with loose debris, which can significantly decrease traction and make it more challenging to control your vehicle. By reducing your speed, you enhance your ability to react to any potential hazards and maintain better control over your car, which is crucial in preventing accidents. Additionally, driving at a slower speed allows for more time to navigate turns and respond to other drivers or obstacles on the road. Increasing your speed or maintaining your usual pace in slippery conditions would increase the risk of losing control of the vehicle, while turning around may not always be a practical or safe option, especially if it could lead to more dangerous situations. Therefore, the key to navigating slippery road conditions safely is to slow down and drive carefully.
