Sample questions from this bank

Two real questions from the Iowa set

These are pulled directly from the Iowa question bank above, not invented for this page. In the practice test itself, the answer and explanation only show after you pick a choice.

Speed limits

In Iowa, unless a sign says otherwise, what is the statutory speed limit in a business or residential district?

25 mph
35 mph
45 mph

Show answer and explanation

25 mph. Iowa's default unposted speed limit for business and residential districts is 25 mph.

Right of way

According to Iowa's driver manual, what is true about right-of-way laws?

They guarantee you the right to proceed no matter what
They only tell drivers who must yield, not who has an absolute right to go
They apply only at intersections with traffic signals

Show answer and explanation

They only tell drivers who must yield, not who has an absolute right to go. The manual explains right-of-way rules assign yielding duties; drivers must still act to avoid a crash regardless of technical right-of-way.
