Illinois Driving Permit Practice Test

What does the sign "no passing zone" signify?

1. Animal crossing

2. Divided highway ends

3. Reduction of lanes

4. Road narrows

The correct answer is: Road narrows

The sign indicating a "no passing zone" signifies that drivers should not attempt to overtake or pass other vehicles in that area. This typically occurs in locations where visibility is limited, such as near curves or hills, or in areas where there are safety concerns. It is crucial to adhere to this sign to ensure the safety of all road users. The other options represent different road conditions or warnings but do not convey the specific instruction to refrain from passing. For instance, the sign for animal crossing indicates the potential for wildlife on the roadway, while the indicator for a divided highway ending signifies the transition from a divided roadway to a non-divided one. The sign for lane reduction warns of a change in the number of lanes available, which also does not directly relate to passing. Thus, the "no passing zone" sign is uniquely focused on the prohibition of overtaking for safety reasons.
