Quick answer
For an unprotected left turn, yield to approaching traffic that is already in the intersection or close enough to create an immediate hazard. Judge how quickly vehicles are approaching, not just how far away they look. Wait when another vehicle blocks your view, check the crosswalk and receiving lane, and turn only when you can complete the movement safely without rushing.

Unprotected left turns require new Arizona drivers to judge closing speed, keep a clear view, and wait for a safe opening. For parents, the challenge is teaching that judgment without rushing a teen into a decision. This guide explains who must yield, how to assess approaching traffic, when an obstructed view means waiting, and how to finish the turn with control.
Identify Who Must Yield Before Judging the Opening
An unprotected left turn requires the driver to assess an opening in opposing traffic. A green light alone does not settle that decision.
Under Arizona’s left-turn yielding law, A.R.S. 28-772, a driver turning left must yield to opposite-direction vehicles already within the intersection or approaching closely enough to present an immediate hazard. Teach your teen to identify that responsibility before considering whether to move.
Signal rules matter, too. A.R.S. 28-645 addresses movement under traffic signals and the applicable duties to yield to vehicles and pedestrians lawfully within the intersection or an adjacent crosswalk. The practical lesson is to read the signal, then assess the entire path.
Before a practice turn, ask your teen to identify:
- The signal or traffic control governing the turn.
- Opposing traffic that could conflict with the movement.
- People crossing or approaching the intended path.
- Whether the receiving lane has room for the vehicle.
Discuss these responsibilities while parked first. During a turn, keep coaching brief enough that your teen can concentrate on driving.
Judge Closing Speed Instead of Distance Alone
A vehicle can look far away while reaching the intersection quickly. Distance is only one part of the decision.
Help your teen watch how rapidly an approaching vehicle changes position. Repeated observations reveal more than a single glance. They also need to account for traffic in every opposing lane that crosses their path, including vehicles less visible behind larger ones.
Avoid teaching a fixed number of seconds as a universally safe gap. The opening needed depends on visibility, intersection layout, vehicle response, and the driver’s ability to complete the turn smoothly. A rule memorized in one setting can create misplaced confidence elsewhere.
Use passenger rides to practice observation without requiring your teen to act. Ask them to describe an approaching vehicle as “closing quickly,” “moving slowly,” or “unclear.” The goal is to recognize uncertainty as a reason to wait.
A useful parent prompt is: “Can you complete the turn without making approaching traffic brake or change course?” It encourages a conservative assessment; it does not replace the legal yielding responsibility.
Around school pickup traffic, your teen may feel pressure from cars behind. Explain beforehand that another driver’s impatience cannot establish a safe opening. Missing an opening is an opportunity to reassess.
Wait When Sight Lines Are Blocked
An opposing vehicle waiting to turn left can hide straight-through traffic beside or behind it. A large vehicle can obscure another lane, while glare can make movement harder to interpret.
If your teen cannot see the traffic they must yield to, they do not have enough information to proceed confidently. An apparently empty patch of pavement is not proof that the whole path is clear.
Teach a simple response: maintain a lawful position, keep observing, and wait for the obstruction to clear. Do not coach your teen to creep into an opposing traffic lane to obtain a better view. If visibility remains inadequate, continuing to a safer legal route may be the better choice.
Parents should also avoid treating a wave from another driver as clearance. That person may be yielding only their own lane and may not see other vehicles, cyclists, or pedestrians.
In Phoenix, North Phoenix, Scottsdale, and Mesa, choose practice routes according to your teen’s demonstrated skill and the conditions you observe that day. Begin with manageable situations before adding more demanding intersections. DVDS’s service-area information can help families plan instruction around where they drive.
After a turn, ask, “What could you see, and what was hidden?” This builds a repeatable habit of identifying missing information before acting.
Complete the Turn Without Drifting
Accepting an opening is only part of the task. Your teen must also follow a lawful path and arrive with the vehicle under control.
Arizona’s turn-positioning statute, A.R.S. 28-751, sets requirements for approaching and making turns and recognizes traffic controls that direct a different course. Teach your teen to check signs and pavement markings before entering the turn.
Keep the practice emphasis on these habits:
- Establish the correct approach position before the intersection.
- Identify the intended receiving lane before moving.
- Scan the crossing area and confirm that the exit remains available.
- Steer through a consistent path without drifting across lane markings.
- Finish the turn before considering a separate, lawful lane change.
A teen who rushes the steering or accelerates abruptly may have accepted an opening they were not comfortable handling. Review the decision afterward instead of encouraging faster execution next time.
Set one learning goal per outing. For example, focus on recognizing blocked views, then discuss the result while parked. Practicing steering in a suitable private parking lot requires the property owner’s permission and does not reproduce the traffic judgment needed at an intersection.
Frequently Asked Questions
Should I tell my teen when to go?
Avoid making “go now” the main coaching method. It can encourage reliance on your timing while your teen has a different view or needs longer to respond. Establish yielding and visibility checks before driving, keep live prompts short, and review decisions afterward. If repeated intervention is necessary, move practice to an easier setting and seek professional instruction.
Is waiting through an opening a mistake?
A missed opening can be useful feedback, especially when your teen cannot explain what they saw. Ask whether the issue was closing speed, a hidden lane, a crosswalk, or uncertainty about the turn path. Build observation and consistency before expecting quicker decisions. Waiting should still follow the signal and applicable rules; it does not remove the need to understand the intersection.
How do lessons fit into my teen’s licensing plan?
Choose instruction around the skills your teen needs to become license-ready, including independent observation and consistent yielding. Confirm the licensing path that applies to your family using the official ADOT permit and license requirements. Ordinary driving-school enrollment does not automatically reduce required supervised practice. If you are considering that pathway, review DVDS’s road test waiver information and confirm current eligibility before selecting a package.
For help turning these habits into consistent driving, contact DVDS at (602) 663-3502. Review lesson packages by hours, curriculum, and intended outcomes to plan license-ready instruction around your teen’s needs, then book driving lessons. Bring specific concerns, such as blocked views or rushed decisions, so instruction can address the judgment your teen needs to develop.
