Road conditions that could affect your riding include
- slippery road markings and tar patches.
- wet leaves, debris or gravel and wet or icy roads.
- storm drains and railroad tracks.
- All of the above ✓
Answer: D. All of the above
All of the above: slippery road markings and tar patches, wet leaves/debris/gravel and wet or icy roads, storm drains and railroad tracks are all road conditions that can affect your riding.
Why this is the answer
The handbook's poor-road-surface list includes loose gravel, wet leaves and debris, railway tracks, wet or icy roads, slippery markings, oil and tar patches, storm drains, and metal surfaces. It says a rider on two wheels can lose traction on rough or slippery surfaces and fall, so scanning for these hazards matters. Each choice names items from that same list; together they cover the categories the handbook warns about, which is why the all-inclusive answer fits.
Why the other answers are wrong
- A. slippery road markings and tar patches. — Slippery road markings and tar patches are listed hazards, but this choice leaves out the other poor surfaces the handbook names, such as gravel, wet leaves, railway tracks, wet or icy roads, and storm drains.
- B. wet leaves, debris or gravel and wet or icy roads. — Wet leaves, debris, gravel, and wet or icy roads are listed hazards, but this choice omits slippery markings, tar patches, storm drains, railway tracks, and metal surfaces.
- C. storm drains and railroad tracks. — Storm drains and railroad tracks are named road-surface hazards, but this choice ignores the slippery markings, tar patches, leaves, debris, gravel, and wet or icy roads in the handbook's list.
Remember it
Use a surface scan: markings, tar, leaves, gravel, ice, drains, tracks, metal — all belong on your hazard list.
