Why are gravel roads hazardous for motorcycle riders?

Answer: D — Less traction

Gravel roads are hazardous for motorcycle riders primarily due to the reduced traction they provide compared to paved roads. Gravel surfaces can be loose and irregular, making it challenging for motorcycles to maintain stability and control. This lack of traction can lead to skidding, sliding, or loss of control, increasing the risk of accidents for riders. Enhanced grip, increased visibility, and wider lanes are not typically associated with gravel roads and do not address the main hazard of reduced traction.
