The correct answer is: C. One side and proceed to other side.
Rolling starts are a common practice in highway construction. They involve closing one lane of traffic and then gradually opening it up again as the construction progresses. This allows traffic to continue flowing while the work is being done, and it also helps to reduce the risk of accidents.
There are a few different ways to do a rolling start. One way is to close the lane on the side of the road that is being worked on, and then gradually open it up again as the work progresses. Another way is to close the lane in the middle of the road, and then gradually open it up again on either side.
The best way to do a rolling start will depend on the specific circumstances of the construction project. However, in general, it is important to make sure that the traffic is flowing smoothly and that there is no risk of accidents.
Here is a brief explanation of each option:
- A. Sides and proceed to center: This option is not typically used in highway construction, as it would require closing both lanes of traffic. This would cause a significant disruption to traffic flow and could increase the risk of accidents.
- B. Center and proceed to sides: This option is also not typically used in highway construction, as it would require closing the center lane of traffic. This would cause a significant disruption to traffic flow and could increase the risk of accidents.
- C. One side and proceed to other side: This is the most common way to do a rolling start in highway construction. It allows traffic to continue flowing on one side of the road while the work is being done on the other side. This helps to reduce the disruption to traffic flow and the risk of accidents.
- D. Any of the above: This option is not correct, as only option C is typically used in highway construction.
