The shoulder provided along the road edge should be A. rougher than the traffic lanes B. smoother than the traffic lanes C. of same colour as that of the pavement D. of very low load bearing capacity

rougher than the traffic lanes
smoother than the traffic lanes
of same colour as that of the pavement
of very low load bearing capacity

The correct answer is: B. smoother than the traffic lanes.

The shoulder is a part of the road that is used for emergency stops and for parking. It is important that the shoulder is smooth so that vehicles can safely pull over or park. If the shoulder is rough, it could damage the tires of vehicles and make it difficult for them to stop.

The other options are incorrect because:

  • Option A is incorrect because a rough shoulder could damage the tires of vehicles and make it difficult for them to stop.
  • Option C is incorrect because the shoulder does not need to be the same color as the pavement.
  • Option D is incorrect because the shoulder needs to have a high load bearing capacity so that vehicles can safely pull over or park.
