a. A crossing where a hump has formed.
b. A danger to low-clearance vehicles.
c. A crossing close to a waterway where whales have been sighted.

Answer 1

A humpback railway crossing is a crossing where a hump has formed, which can be a danger to low-clearance vehicles.

Step-by-step explanation:

A humpback railway crossing is a crossing that is both a. and b. correct. It is a crossing where a hump has formed, which can be a danger to low-clearance vehicles. When the road or track rises and then drops again to level ground, it forms a hump, which can cause problems for vehicles with low ground clearance. Therefore, option d. a. and b. are correct.
