Question

Difficulty: MediumWarning Signs

A yellow, diamond-shaped warning sign displaying an advisory speed plaque (such as '35 MPH') below a curve symbol establishes an enforceable statutory speed limit, meaning a driver can be ticketed strictly for exceeding that speed regardless of road conditions.

Answer: Answer

Answer

False. Yellow warning signs with advisory speed plaques advise drivers of a recommended safe speed for upcoming road hazards under ideal conditions, whereas legally binding statutory speed limits are posted on rectangular black-and-white regulatory signs.
Yellow warning signs and associated advisory speed plaques recommend safe operating speeds for specific roadway hazards under ideal conditions. They differ from regulatory signs, which are rectangular white signs that state legally enforceable maximum speed limits.

Step-by-Step Solution

1
Identify the sign category and color coding
Yellow diamond-shaped signs are warning signs designed to alert drivers to upcoming hazards, curves, or road conditions.
Sign color and shape dictate whether a traffic control device is a warning sign (yellow diamond) or a regulatory sign (black-and-white rectangle).
2
Distinguish between advisory speed plaques and regulatory speed limits
Advisory speed plaques convey recommended maximum safe speeds for specific road geometry (like sharp curves), while regulatory speed signs enforce statutory legal speed limits.
Understanding MUTCD sign classifications ensures proper compliance with traffic laws and hazard awareness.
