Turning is where many new drivers crash; improper or careless turning contributed to 459 crashes involving 17-year-old PA drivers in 2017. Good turns come from the right speed, the right lane position, and a clear path before you commit.

Know the rule

Speed is probably the most important factor in a turn. Slow to a speed that lets you keep control, stay in your lane and react to the unexpected. Watch for pedestrians and traffic on the street you're entering.

Handbook p. 49 ↗

To complete a turn safely

  • Signal three to four seconds before your turn
  • Position your vehicle in the proper lane
  • Control your speed
  • Complete your turn in the proper lane
Handbook p. 49 ↗

Know the rule

On a two-lane, two-way road, start left turns as close to the centerline as possible and right turns as close to the right edge as possible. On multi-lane roads, turn left from the left lane and right from the right lane.

Handbook p. 49 ↗

Know the rule

Turn into the closest lane going your way: left turns into the left lane, right turns into the right lane. Change lanes only after the turn is complete.

Handbook p. 49 ↗
Turning into the correct lane
Turning into the nearest lane

Know the rule

A middle lane marked with a solid outer line and a broken inner line on each side is a center turn lane. Drivers from either direction begin left turns there, and drivers from a cross street may finish a left turn there before merging.

Handbook p. 49 ↗

Using a center turn lane safely

  • Signal at least three to four seconds before entering it
  • Don't enter too soon; the longer you're in it, the likelier a head-on meeting
  • Enter it completely; don't leave your rear end in the travel lane
  • Turn only with a big enough gap; watch for vehicles coming at you in the same lane
Handbook p. 49 ↗

Know the rule

In a center turn lane, watch for oncoming drivers in the same lane and for vehicles turning into it from driveways and cross streets.

Handbook p. 49 ↗
500 feet

For a U-turn, drivers from all directions must be at least this far away and able to see you clearly

Handbook p. 50 ↗
No U-turn
NO U-TURN sign

Know the rule

U-turns are allowed only if they don't endanger other traffic. They're not allowed on curves, when approaching or near the crest of a hill, or where a NO U-TURN sign is posted.

Handbook p. 50 ↗
No turn on red
NO TURN ON RED sign

Know the rule

Unless a NO TURN ON RED sign is posted, you may turn right on red after stopping and yielding to pedestrians and cross traffic. The sign is usually beside the road on the near side of the intersection and near the signal on the far side.

Handbook p. 50 ↗

Crossing traffic safely

  • The space you need depends on the road, the weather and oncoming traffic
  • Stop halfway across only if a center median turn lane can hold your entire vehicle
  • Even on green, don't enter an intersection if vehicles block your way
  • Don't pull out in front of a car with its turn signal on; wait until it actually turns
  • Use extra caution crossing traffic near hills or curves
Handbook p. 50 ↗

Put it into practice

An oncoming car has its right signal on as you wait to turn left. Don't assume it's turning: the driver may be turning just past you, may have changed plans or forgotten the signal. Wait until the car actually starts to 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.

Stopping halfway across a street is considered safe only when:
  1. Traffic is light
  2. You have your hazard lights on
  3. It's during daylight hours
  4. A center turn lane is provided large enough to hold your entire vehicle

Answer: A center turn lane is provided large enough to hold your entire vehicle

You may only stop halfway across when a median turn lane can fully contain your vehicle.

Handbook p. 50 ↗
On a two-lane, two-way road, where should you position your vehicle to begin a left turn?
  1. As close to the right edge as possible
  2. In the middle of your lane
  3. It does not matter
  4. As close to the centerline as possible

Answer: As close to the centerline as possible

Left turns on two-lane roads should start from as close to the centerline as possible.

Handbook p. 49 ↗
When entering a center turn lane to make a left turn, how early should you signal?
  1. Immediately upon entering the lane
  2. At least 10 seconds before entering
  3. 3–4 seconds before entering
  4. Signaling is optional in a center lane

Answer: 3–4 seconds before entering

Signal 3-4 seconds before entering a center turn lane so others can anticipate your move.

Handbook p. 49 ↗
When making a U-turn, how far away must approaching drivers be for it to be considered safe?
  1. At least 100 feet
  2. At least 1,000 feet
  3. At least 200 feet
  4. At least 500 feet

Answer: At least 500 feet

You need drivers from all directions to be at least 500 feet away to make a safe U-turn.

Handbook p. 50 ↗
Where are U-turns specifically prohibited, according to the handbook?
  1. On curves or near the crest of a hill
  2. On any two-lane road
  3. Only in business districts
  4. Only where speed limits exceed 45 mph

Answer: On curves or near the crest of a hill

U-turns are illegal on curves or when approaching/nearing the crest of a hill.

Handbook p. 50 ↗
On a two-lane, two-way road, left turns should begin from as close to the centerline as possible.
  1. True
  2. False

Answer: True

Positioning near the centerline is correct for beginning a left turn on a two-lane road.
