Illinois DMV Permit Test: Speed, Passing, and Parking Concepts

Importance ★★★★☆ · 15% (estimate)

Overview

This chapter covers Illinois speed limits, how to pass safely, and the places where you may not park. Many questions use exact numbers, so learn them together.

When no other limit is posted, the Illinois speed limit is 30 mph in an urban district, 15 mph in an alley, and 55 mph on most other highways. Some highways, such as interstates, have higher posted limits. In a school zone, the limit is 20 mph on school days when children are present. The posted limit is for good conditions, so drive slower in snow, rain, fog, or heavy traffic.

Pass on the left, and only where you can see far enough ahead. Never pass on a hill or curve where you cannot see oncoming traffic. When someone is passing you, stay in your lane and do not speed up.

Do not park within 15 feet of a fire hydrant, within 20 feet of a crosswalk at an intersection, within 30 feet of a stop sign, yield sign, or traffic signal on the side you approach from, or within 50 feet of the nearest rail of a railroad crossing. Stay at least 20 feet from a fire station driveway on the same side of the street. When you park downhill next to a curb, turn your wheels toward the curb.

  • Driving for conditions

    The posted limit is the most you may drive in good conditions. In bad weather or heavy traffic, drive slower so you can stop safely.

    Memory tipThe limit is a maximum, not a target.

  • Passing

    Pass on the left, and only when you can see far enough ahead. Do not pass on hills or curves. When you are being passed, keep your lane and do not speed up.

    Memory tipCan't see ahead? Don't pass.

  • No parking distances

    Do not park within 15 feet of a fire hydrant, 20 feet of a crosswalk at an intersection, 30 feet of a stop sign or traffic signal on the approach side, 50 feet of the nearest rail of a railroad crossing, or 20 feet of a fire station driveway on the same side.

Key point: Park at least 15 feet from a fire hydrant

You may not park within 15 feet of a fire hydrant. Firefighters need room to reach it quickly.

Wrong choices

  • No closer than 5 feet: 5 feet is far too close.
  • No closer than 10 feet: 10 feet is still too close. The rule is 15 feet.
  • No closer than 30 feet: 30 feet is the distance for a stop sign, not a hydrant.
