Most crashes happen at intersections. Slow down, search in a set pattern, and position your car correctly before, during and after the turn.

At every intersection, reduce speed and search for:

  • Traffic control devices
  • Oncoming and cross traffic, including motorcycles and bicycles — look left, right, then left again
  • Pedestrians
  • Roadway conditions
  • Areas of limited visibility
Handbook p. 19 ↗

When turning:

  • Signal your intentions
  • Search all corners for traffic controls, pedestrians and vehicles
  • Get into the lane closest to the direction you want to go
  • Look through the turn to the farthest point along your path
  • Accelerate smoothly, make sure your signal cancels, and check traffic behind

100 feet

Signal at least this far before the turn — by turn signal or hand/arm signal

Handbook p. 20 ↗
Hand and mechanical turn signals
Turn signal lever and hand signals: left, right, and slow/stop

Know the rule

Right turns: don't swing wide to the left. Turn from the right-most part of your lane into the right-most part of the new street.

Handbook p. 20 ↗

Know the rule

Left turns: yield to oncoming traffic. Turn from the left-most part of your lane into the lane farthest left, just right of the center line — on four-lane highways too.

Handbook p. 20 ↗

Know the rule

Turning left on a green light: if traffic is heavy, position the front of your car slightly past the stop bar, yield to pedestrians and oncoming traffic, and turn when safe.

Handbook p. 20 ↗

Know the rule

Multiple turn lanes: pick the lane you'll turn from and stay in it until the turn is complete.

Turning on a red signal

Handbook p. 20 ↗
Left turn on red from a one-way street
Left on red: from a one-way street onto another one-way street

Intersection tips:

  • An approaching car's signal doesn't prove it will turn — don't pull out without assured distance
  • At a stop sign where you can't see crossing traffic, edge forward to check
  • Wait for a gap big enough to cross, turn into the right lane and get up to speed
Handbook p. 21 ↗

Put it into practice

You're stopped on red on a one-way street, in the far-left lane, and the cross street is also one-way to the left. After a full stop and yielding to traffic and pedestrians, you may turn left — unless a sign forbids it.

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.

Besides a mechanical turn signal, how else may you give the required signal before a turn?
  1. By flashing your headlights
  2. With the appropriate hand-and-arm signal
  3. By tapping your brakes twice
  4. By turning on your hazard lights

Answer: With the appropriate hand-and-arm signal

A turn signal must be given at least 100 feet before the turn, using either a mechanical signal or the appropriate hand/arm signal.

Handbook p. 20 ↗
From which part of your lane should you make a right turn?
  1. The center of your lane
  2. The leftmost portion of your lane
  3. The rightmost portion of your lane
  4. Whichever portion has the least traffic

Answer: The rightmost portion of your lane

Always turn right from the rightmost portion of your lane into the rightmost portion of the street you're entering.

Handbook p. 20 ↗
Before turning right on red, what must you do?
  1. Slow down but you don't need to stop if clear
  2. Signal only, no stop required
  3. Wait for a green arrow
  4. Come to a complete stop and yield to crossing traffic and pedestrians

Answer: Come to a complete stop and yield to crossing traffic and pedestrians

You must come to a complete stop and let all crossing traffic and pedestrians clear before turning right on red.

Handbook p. 20 ↗
When is a left turn on red permitted in Ohio?
  1. Only from the far-left lane of a one-way street onto another one-way street
  2. From any lane onto any street
  3. From a two-way street onto a one-way street
  4. Never — all left turns on red are banned

Answer: Only from the far-left lane of a one-way street onto another one-way street

A left turn on red is legal only from the extreme left lane of a one-way street onto another one-way street, unless prohibited.

Handbook p. 20 ↗
An oncoming vehicle has its left turn signal on as you approach an intersection. What should you assume?
  1. That it is definitely turning and you may proceed
  2. Nothing for certain — don't pull out until clear
  3. That it will stop to let you go first
  4. That it is switching lanes, not turning

Answer: Nothing for certain — don't pull out until clear

Don't assume the vehicle is turning — it may turn after passing you or the driver may have forgotten to cancel the signal.

Handbook p. 21 ↗
You're on a one-way street approaching another one-way street, and a red light is showing with no sign prohibiting a turn. Can you turn left on red?
  1. Yes, from the far-left lane
  2. No, left turns on red are never allowed
  3. Yes, from any lane
  4. Only if a police officer waves you through

Answer: Yes, from the far-left lane

A left turn on red is legal only from the extreme left lane of a one-way street onto another one-way street, unless prohibited.
