Step 1: Identify the given data.
The question asks for the traffic sign represented by a rectangular shape with a red border and a black diagonal line. The options are:
(1) No U-turn
(2) No overtaking
(3) No entry
(4) No parking
We need to determine which traffic sign matches this description.
Step 2: Recall the standard shapes and symbols for traffic signs.
Traffic signs are standardized to convey specific instructions to drivers clearly and universally. The shape, color, and symbols on the sign indicate its meaning:
Shapes: Circular signs often indicate prohibitions or mandatory instructions, triangular signs indicate warnings, and rectangular signs typically provide information or regulations.
Colors: A red border usually indicates a prohibition.
Symbols: The specific symbol inside the sign provides the exact instruction.
Step 3: Analyze the description of the sign.
The sign is described as:
Rectangular shape: This is typically used for regulatory or informational signs.
Red border: Indicates a prohibition (something is not allowed).
Black diagonal line: A diagonal line often signifies a restriction, such as prohibiting a specific action.
Step 4: Match the description with the options.
Let’s evaluate each option based on standard traffic sign designs (e.g., as per Indian traffic sign standards or international conventions like the Vienna Convention on Road Signs and Signals):
Option 1: No U-turn
The "No U-turn" sign is typically a circular sign with a red border and a black U-shaped arrow pointing upward, often with a diagonal line through it. The shape is circular, not rectangular, so this does not match the description.
Option 2: No overtaking
The "No overtaking" sign is often a rectangular sign with a red border and a black diagonal line running from the top left to the bottom right. Sometimes, it includes symbols of two vehicles, but the key feature is the rectangular shape with a red border and a diagonal line, indicating that overtaking is prohibited. This matches the description provided.
Option 3: No entry
The "No entry" sign is typically a circular sign with a solid red background and a white horizontal bar or no symbol at all. It does not have a rectangular shape or a black diagonal line, so this does not match.
Option 4: No parking
The "No parking" sign is usually a circular sign with a red border and a blue background, often with a "P" symbol crossed by a diagonal line. It is not rectangular, so this does not match the description.
Step 5: Confirm the correct sign.
The "No overtaking" sign aligns with the description of a rectangular shape, red border, and black diagonal line. This sign is used to prohibit overtaking on roads where it is unsafe, such as narrow roads or areas with poor visibility. The rectangular shape with a red border and diagonal line is a common design for this restriction in many standards, including those in India.
Step 6: Select the correct option.
The traffic sign represented by a rectangular shape with a red border and a black diagonal line is "No overtaking," matching option (2).
\[ \boxed{\text{No overtaking}} \]
