Left-turn accidents commonly occur because drivers fail to yield, misjudge the speed of oncoming vehicles, become distracted, or make turns against traffic signals. Unlike a simple lane change, a left turn often requires a driver to cross the path of vehicles traveling in the opposite direction.
This creates several opportunities for a collision, especially at busy intersections. Understanding the common causes of left-turn accidents can help drivers recognize risks and make safer decisions behind the wheel.
Failure to Yield the Right of Way
Failing to yield is one of the most common causes of left-turn crashes. A driver making a left turn generally needs to wait for approaching traffic that has the right of way. Problems can arise when a motorist assumes an approaching vehicle is far enough away to allow the turn.
Drivers may also incorrectly believe that they have enough time to complete the maneuver. However, an approaching vehicle can cover a considerable distance in only a few seconds, particularly when traveling at a high speed.
For example, Arizona Revised Statutes § 28-645 requires drivers to obey traffic-control signals, including indications governing when vehicles may proceed through an intersection. Disregarding a traffic signal while making a turn can therefore create both safety and legal consequences.
Misjudging the Speed of Oncoming Traffic
Another common problem is incorrectly estimating how fast an approaching vehicle is traveling. A vehicle may appear relatively far away, but if it is moving quickly, the available time to complete a left turn may be much shorter than the turning driver expects.
This can result in a collision when the turning vehicle enters the intersection directly in front of the approaching vehicle. Drivers should consider both distance and speed instead of relying only on how far away another vehicle appears.
Distracted Driving
Distraction can make left turns particularly dangerous because drivers need to monitor multiple sources of information at the same time. A motorist looking at a phone, changing music, adjusting navigation, or focusing on passengers may fail to notice approaching traffic or a changing signal.
Even a brief distraction can be enough to cause a driver to miss an important warning. Drivers should put away their phones and focus completely on the roadway before beginning a turn.
Running or Misreading Traffic Signals
Traffic signals are designed to organize vehicle movements and reduce conflicts at intersections. Crashes can occur when drivers run red lights, misunderstand turn signals, or attempt to rush through an intersection as a light changes.
A protected left-turn arrow generally provides a clearer opportunity to turn because opposing traffic is stopped. When no protected signal is available, drivers need to carefully evaluate the roadway before proceeding.
Poor Visibility
Obstructions can make it difficult for drivers to see approaching vehicles. Parked cars, large trucks, landscaping, buildings, weather conditions, and darkness can all reduce visibility.
Drivers should not assume that an obstructed roadway is clear. When visibility is limited, taking a few additional seconds to check for approaching traffic can prevent a serious crash.
Unsafe Turning Decisions
Some drivers make left turns too quickly or attempt to squeeze through small gaps in traffic. Aggressive driving and impatience can cause motorists to take risks that they might otherwise avoid.
A safe driver should wait for an adequate gap rather than trying to beat an approaching vehicle. It is also important to check for pedestrians and bicyclists before completing the turn.
How Drivers Can Reduce the Risk
Drivers can lower the likelihood of a left-turn collision by slowing down near intersections, staying focused, obeying traffic signals, checking for pedestrians, and yielding when required. Leaving enough time and space to complete a turn is safer than making an uncertain maneuver.
If a crash does occur, photographs, witness information, traffic-camera footage when available, police reports, and medical records may help establish what happened and who may be responsible.
Key Takeaways
- Failing to yield is a major cause of left-turn collisions.
- Misjudging an approaching vehicle’s speed can lead to dangerous turns.
- Distracted driving reduces a driver’s ability to recognize hazards.
- Traffic signals should always be followed when making a left turn.
- Poor visibility and aggressive driving can increase intersection risks.
- Drivers should wait for a safe and adequate gap before turning.
