Question: 1 / 400

Which sign warns drivers of a low overhead clearance?

Railroad sign

Cross-road

Construction sign

The correct answer is the construction sign. This sign specifically indicates that there may be work in the area, which often involves low overhead clearances due to temporary structures like scaffolding or equipment. Construction signs are typically used to alert drivers to changes in the road conditions, including potential hazards such as reduced clearance.

In contrast, railroad signs indicate the presence of a railroad crossing but do not specifically warn about overhead clearance. Cross-road signs alert drivers to intersections with other roads and generally do not provide information about overhead obstacles. Side road signs indicate that traffic may be entering from a side road but do not address clearance issues above the roadway. Understanding these distinctions can help drivers navigate safely and avoid hazards associated with low overheads.
