Question

Difficulty: EasySpace Overhead

Road repaving and packed snow can decrease the overhead clearance under bridges and overpasses without the posted clearance signs being updated.

Answer: Answer

Answer

True
The statement is true because physical changes to the roadway surface, such as new layers of pavement or packed snow, raise the ground level and reduce overhead space without the posted warning sign necessarily being updated.

Step-by-Step Solution

1
Evaluate the factors affecting vertical clearance under overhead structures.
Identify that roadway resurfacing (repaving) and snow or ice accumulation raise the road surface.
Raising the road surface reduces the distance between the road and overhead structures.
2
Determine the accuracy and timing of overhead signage updates.
Clearance signs are not always immediately changed or updated after repaving or during winter weather.
Signs reflect past measurements and do not automatically reflect new pavement layers or seasonal buildup.
