Illinois Driving Permit Practice Test

What is the speed limit in a residential area unless otherwise posted?

1. 25 mph

2. 30 mph

3. 35 mph

4. 40 mph

The correct answer is: 30 mph

In Illinois, the speed limit in residential areas is typically set at 25 miles per hour unless otherwise indicated by posted signs. This limit is established to enhance safety in neighborhoods where pedestrians, particularly children, are likely to be present and where vehicles may frequently enter and exit driveways. Maintaining this lower speed helps reduce the likelihood of accidents and gives drivers more time to react to unexpected situations, such as a child chasing a ball into the street or a cyclist. While the 30 mph speed limit in other options might seem reasonable for some areas, it does not apply to residential neighborhoods, as those areas are designed for lower speeds to prioritize the safety of residents and pedestrians. It is essential for drivers to comply with posted speed limits to ensure the safety of everyone in their community.
