Warning Signs in Traffic Control

In traffic control, warning signs are meant to alert drivers of hazards or potential dangers on the road ahead. These signs are usually triangular in shape, with a bright yellow background and a black border. The warning symbol or message is also displayed in black.

Types of Warning Signs

There are various types of warning signs used in traffic control, and they include:

- Warning signs for curves
- Warning signs for intersections
- Warning signs for pedestrian crossings
- Warning signs for level crossings
- Warning signs for slippery roads
- Warning signs for animals crossing

Answer Explanation

The correct answer to the question is option A, "level crossing." A level crossing is a location where a railway line crosses a road, and it is a potential hazard to road users. Therefore, a warning sign is used to alert drivers of the potential danger ahead.

Option B, "no parking," is not a warning sign but a regulatory sign that controls parking on a particular road. Option C, "end of speed limit," and option D, "overtaking prohibited," are regulatory signs that control the speed limit and overtaking on a particular road, respectively. They are not warning signs.

In summary, warning signs are used in traffic control to alert drivers of potential hazards on the road ahead. They are usually triangular in shape, with a bright yellow background and a black border, and they come in various types, including level crossing, curves, intersections, pedestrian crossings, slippery roads, and animals crossing.
