Traffic Engineering MCQ with answer and solution

Concept

Classification of road traffic signs

Formula

NONE

Step-by-step solution

1. Road signs are classified into Regulatory (Mandatory), Cautionary (Warning), and Informative signs. 2. A Stop sign directs drivers to come to a full halt, enforcing a legal obligation on road users. 3. Because compliance with it is mandatory by law, a Stop sign comes under Regulatory Signs. Answer: A

Explanation

Regulatory signs communicate mandatory traffic laws, regulations, or legal restrictions that road users must follow. A stop sign mandates that drivers come to a complete halt before proceeding through an intersection. Because compliance is legally enforceable, a stop sign falls under the category of regulatory signs.

Why the other options are wrong

B) Cautionary signs warn road users of hazardous conditions ahead. C) Informative signs provide directions, routes, and facility locations. D) Option A is correct because Stop signs give mandatory directions to drivers.

Shortcut

STOP sign mandates compliance by law, so it is a Regulatory Sign.

Common mistake

Misclassifying the Stop sign as a Cautionary sign because of its high-priority warning appearance.
