Illinois Driving Permit Practice Test

The "no passing zone" warning sign is crucial for ensuring safe driving conditions, especially in areas where visibility is limited or where passing might pose significant risks. This sign does not indicate construction, a speed limit change, an interstate ramp, or a turning lane. Instead, it alerts drivers that they are entering a section of the road where overtaking other vehicles is prohibited due to safety concerns. The intention is to prevent accidents that could occur when trying to pass in areas where it's unsafe to do so. Understanding this sign is vital for maintaining safety on the road.
