Signals tell other road users what you're about to do before you do it. Illinois sets minimum signaling distances, defines the hand signals, and spells out how to position your car for right and left turns.

200 feet

Right turns:

  • Signal from the proper turning lane and obey signs and signals
  • Yield to pedestrians, emergency vehicles and vehicles in the intersection
  • Check traffic approaching from the left
  • Follow the curve of the curb, staying as close to it as possible
  • Turn into the right-hand lane of the road you're entering
  • Trucks and buses may need more room to turn right
  • Watch bike lanes for bicyclists approaching the intersection

Left turns:

  • Signal from the proper turning lane and obey signs and signals
  • Yield to pedestrians, emergency vehicles and vehicles in the intersection
  • Check all approaching traffic
  • Keep your wheels pointed straight ahead until you start the turn
  • Finish the turn in the lane closest to your intended direction

Handbook p. 35 ↗
500 feet

Don't make a U-turn on a curve or hill unless you can see at least this far in all directions

Handbook p. 35 ↗

Know the rule

Municipalities may prohibit U-turns on some roadways.

Handbook p. 35 ↗

Hazard signal: flashing both turn signals at once indicates a disabled or parked vehicle.

Handbook p. 35 ↗

Two-way left turn lane

A center lane, marked with yellow lines and white arrows, for left turns at intersections or into and out of mid-block driveways.

Handbook p. 35 ↗

Know the rule

When a two-way left turn lane is provided, don't turn left from any other lane. Drive in it only to prepare for or make a left turn, or a U-turn where permitted.

Handbook p. 83 ↗

Know the rule

When turning or changing lanes in a construction zone, pay special attention to signs, barricades and pavement markings.

Handbook p. 35 ↗

Put it into practice

You're on a residential street and plan to turn right at the next corner. Turn on your right signal at least 100 feet before the turn and keep it on continuously until you turn.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

In a business or residential area, how far before turning must you give a continuous turn signal?
  1. 25 feet
  2. 100 feet
  3. 50 feet
  4. 200 feet

Answer: 100 feet

Signal at least 100 feet before turning in business/residential areas.

Handbook p. 33 ↗
In areas other than business/residential districts, how far before turning must you signal?
  1. 100 feet
  2. 200 feet
  3. 50 feet
  4. 300 feet

Answer: 200 feet

Outside business/residential districts, signal at least 200 feet before turning.

Handbook p. 33 ↗
Using hand-and-arm signals, a left arm pointed straight down signals a right turn.
  1. True
  2. False

Answer: False

False. A left arm extended straight up signals a right turn; an arm extended downward means slowing down or stopping.

Handbook p. 33 ↗
Which hand-and-arm signal means slowing down or stopping?
  1. Left arm and hand extended straight out
  2. Left arm and hand extended downward
  3. Left arm and hand extended straight up
  4. Right arm waved forward

Answer: Left arm and hand extended downward

A downward-extended left arm signals slowing or stopping.

Handbook p. 33 ↗
When making a right turn, where should you position your vehicle?
  1. Stay in the center of the lane
  2. Keep close to the curb
  3. Position toward the left of your lane
  4. Swing wide into the oncoming lane

Answer: Keep close to the curb

Follow the curve of the curb closely when making a right turn.

Handbook p. 34 ↗
Under what condition can you legally make a U-turn on a curve or hill?
  1. Anytime traffic is light
  2. Never, even with good visibility
  3. If you can see 500 feet in all directions
  4. Only during daylight hours

Answer: If you can see 500 feet in all directions

A 500-foot sight distance in all directions is required to turn around on a curve or hill.
