50 m
100 m
150 m
250 m
Answer is Right!
Answer is Wrong!
The correct answer is B. 100 m.
A clearway is a section of road that is kept clear of obstructions to allow vehicles to safely stop in an emergency. The minimum width of a clearway is 100 m. This is to ensure that there is enough space for a vehicle to come to a stop without hitting anything.
Option A is incorrect because 50 m is not enough space for a vehicle to come to a stop safely. Option C is incorrect because 150 m is more space than is required. Option D is incorrect because 250 m is too much space and would be inefficient use of land.
