A speed restriction sign:
Answers
May be ignored in rainy, snowy, or icy conditions.
Has a triangular shape.
Is blue with black lettering.
Shows a recommended speed for a curve or turn.
The Correct Answer and Explanation is :
The correct answer is: Shows a recommended speed for a curve or turn.
Explanation:
Speed restriction signs are typically used to guide drivers on the safe speed to maintain under certain road conditions. These signs are designed to improve road safety by helping drivers adjust their speed according to the road’s geometry and other factors that may affect vehicle control. The following explains each aspect mentioned in the choices:
- May be ignored in rainy, snowy, or icy conditions:
This statement is incorrect. Speed restrictions, such as those for curves or turns, should not be ignored during adverse weather conditions. In fact, these conditions typically require even more caution, and drivers should adjust their speed to be even slower than the recommended limit to maintain control of the vehicle. - Has a triangular shape:
This is incorrect. While warning signs like yield or pedestrian crossing signs do indeed have a triangular shape, speed restriction signs, especially those indicating a safe speed for a curve, are typically round. Round signs are used to convey specific speed-related information, indicating a recommended or maximum speed for upcoming road conditions. - Is blue with black lettering:
This is not correct for speed restriction signs. Speed limits are usually displayed on white or black signs with black text, while blue signs are used for regulatory signs that indicate guidance or specific rules (e.g., parking regulations) rather than speed limits. - Shows a recommended speed for a curve or turn:
This is the correct answer. Many road curves or turns have signs that display a recommended speed for that section of the road. These signs are intended to help drivers maintain safe speeds in the face of potentially dangerous or sharp turns. The speed listed is a recommendation for optimal handling and safety, ensuring that the driver can navigate the curve or turn without losing control of the vehicle.
In summary, speed restriction signs help ensure safety, particularly in curves or areas with specific risks, and should always be adhered to for both optimal safety and legal compliance.
