In which area should a rider avoid riding during inclement weather?

Riders should avoid painted road markings or steel grates during inclement weather because these surfaces can become extremely slippery when wet. The slickness of these materials poses a heightened risk of losing traction, which can lead to accidents. Painted markings are often made from materials that don’t grip tires effectively in wet conditions, and when water collects on top, they can create a layer of moisture that significantly reduces friction.

In contrast, while gravel roads, curves, and urban streets all present their own hazards in bad weather, the specific risk associated with painted markings and steel grates is particularly pronounced. For instance, gravel can provide some traction, even when wet, and urban streets may have other forms of grip despite their slickness. Curves can be tricky, but riders can prepare and manage their speed accordingly. Hence, painted road markings and steel grates are especially hazardous during rain, making it crucial for riders to avoid them.
