Answer: A. Gravel provides less traction than pavement.
Gravel roads are potentially dangerous to motorcyclists because gravel provides less traction than pavement.
Why this is the answer
The motorcycle handbook states directly that traction on gravel roads is not as good as on pavement. It also notes that some gravel areas are better than others and advises staying in the tire tracks, away from loose gravel at the road edge. With less grip than a paved surface, gravel can make the motorcycle harder to control, which is why it is treated as a dangerous surface.
Why the other answers are wrong
- B. Other drivers are known to drive recklessly. — The passages do not mention reckless driving by other drivers as a danger specific to gravel roads.
- C. They do not have posted speed limits. — The passages do not say that gravel roads lack posted speed limits.
- D. There are no lane markers. — The passages do not mention missing lane markers; the stated issue is poorer traction on gravel.
Remember it
Think of your tires looking for a firm track: loose edge gravel gives less grip, so stay in the tire tracks.
