Motorcycles are advised to use extreme caution when going over steel plates on the road due to several reasons:
Reduced Traction: Steel plates often have a smooth surface, which can significantly reduce the traction between the motorcycle tires and the road. This reduced traction makes it easier for the motorcycle to slip or slide, especially if the road is wet, oily, or if the plates are uneven or slippery.
Unpredictable Surface: Steel plates can sometimes be unevenly placed or not securely fastened. This can create an unpredictable surface for motorcycles, causing instability and potential loss of control. Sudden changes in the road surface can be challenging to navigate, especially at higher speeds.
Shifting Plates: Steel plates can shift slightly when vehicles pass over them, leading to an uneven surface. This shifting can create an additional hazard for motorcycles, as their narrower tires may be more affected by the sudden changes in the road's level.
Edge Hazards: Steel plates are often installed to cover construction or repair areas on the road. The edges of these plates can be raised or have gaps, which can pose a risk for motorcycles with thinner tires. Hitting an edge at an angle can result in a loss of control or instability.
Given these factors, motorcyclists are advised to exercise caution when encountering steel plates on the road. It is recommended to reduce speed, maintain a firm grip on the handlebars, and avoid sudden maneuvers or braking while passing over them. Assessing the condition of the plates, being alert to changes in traction, and adjusting riding technique accordingly can help mitigate the risks associated with steel plates on the road.
