What should a rider specifically look for when riding on a rainy road?

When riding on a rainy road, it is crucial for a rider to be aware of slick road conditions. Rain can create a film of water on the pavement, which can reduce tire traction significantly. This combination can lead to loss of control, especially in the first few minutes of rainfall when oil and debris are mixed with water, creating particularly hazardous conditions.

Recognizing these slick conditions allows the rider to adjust their speed and riding style accordingly, such as increasing following distance, reducing speed when cornering, and being more cautious when applying brakes. While being mindful of other hazards like rocks, vehicles' headlights, and traffic signals is important, the primary concern in rainy conditions is the slippery nature of the road, making awareness of slick road surfaces vital for safety.
