Final answer:
The correct answer is C. No Trucks, as this indicates a specific prohibition for trucks to enter a roadway, which aligns with the context of the question.
Step-by-step explanation:
When a sign indicates that trucks are prohibited from entering a roadway, it usually specifies a particular restriction relevant to vehicles of that nature. If the sign states that there is a weight limit, it refers to the maximum weight of vehicles allowed on that road, typically to protect the structural integrity of the road or a bridge. A No Parking sign would only restrict the stopping and leaving of vehicles in that area. The sign No Trucks specifically prohibits the entry of trucks onto that roadway, which could be for several reasons such as preserving road conditions, preventing congestion, or due to road design not being suitable for larger vehicles. Lastly, No Overtaking would be a restriction on passing other vehicles on that stretch of road. In this scenario, the correct answer to the question would be C. No Trucks, as this is the only option that directly prohibits trucks from entering the roadway.
