Driver Mistakes That Cause Bicycle Crashes in San Diego

San Diego’s beautiful biking routes shouldn’t come at the cost of safety—but each year, hundreds of cyclists are seriously injured or killed due to driver negligence. At Hulburt Law Firm, we’ve helped numerous injured cyclists navigate the aftermath of accidents caused by distracted, impaired, and reckless drivers.

Below are the most common causes of bicycle crashes in San Diego—and what legal rights victims have.

‍

1. Distracted Driving: A Leading Cause of Bicycle Accidents

Distracted driving is a widespread problem, and it’s especially dangerous for cyclists sharing the road with inattentive drivers. Distractions can come in many forms, but some of the most common include:

• Texting and Phone Use: California law prohibits using a cell phone without a hands-free device, yet many drivers still text, browse or make calls while driving. These actions take the driver’s eyes, hands, and focus off the road, increasing the likelihood of missing a cyclist. National studies show drivers using mobile devices are nearly four times more likely to crash. In fact, even holding a hands-free conversation while driving poses safety risks because the brain is focused on the conversation—and not the road.
• Eating, Drinking, or Grooming: Simple activities like eating, drinking, or adjusting the stereo can divert a driver’s attention long enough to cause an accident.
• Using Navigation Systems: While GPS can be useful, adjusting a navigation system or glancing down to check directions can result in a driver failing to notice a nearby cyclist.

When a driver is distracted, they’re less likely to see a cyclist in time to avoid an accident. Even a split-second distraction can be deadly when it leads to a collision with a vulnerable bicyclist.

2. Speeding: Increased Impact and Reduced Reaction Time

Speeding is another common cause of bicycle accidents. When drivers exceed the speed limit or drive too fast for road conditions, several risks emerge:

• Reduced Reaction Time: The faster a car is going, the less time the driver has to see and react to a cyclist, especially if the cyclist appears suddenly or if the driver is turning.
• Increased Impact Severity: The force of impact in a crash grows exponentially with speed. Even if the driver attempts to stop, a speeding car can cause devastating injuries to a cyclist, often leading to broken bones, traumatic brain injuries, or fatal injuries.
• Difficulty with Curves and Corners: Cyclists are often less visible around bends or intersections. Speeding drivers may struggle to safely navigate these areas, increasing the risk of collision.

Speeding drivers create an unpredictable environment, which can be especially dangerous for cyclists who depend on drivers’ caution to stay safe.

3. Failure to Yield: A Common Cause of Intersection and Crosswalk Accidents

Failure to yield is a frequent form of driver negligence that puts cyclists at high risk, particularly at intersections, crosswalks, and bike lanes. California law mandates that drivers yield to cyclists in certain situations, but these laws are often ignored or misunderstood. Common instances of failure to yield include:

• Right Turns Across Bike Lanes: Drivers making right turns are required to merge safely into bike lanes to avoid cutting off cyclists. However, many drivers don’t check for cyclists before crossing a bike lane, leading to dangerous right-turn accidents.
• Left Turns Across Traffic: When making a left turn, drivers must yield to oncoming traffic, including cyclists. Failure to properly gauge the speed and distance of an oncoming cyclist can result in a severe collision.
• Entering Intersections: Cyclists in crosswalks or intersections often have the right of way, but drivers may fail to yield if they are in a rush or misjudge the cyclist’s speed. This is especially common when drivers make rolling stops or try to “beat” a cyclist through an intersection.

Failure to yield is a serious form of negligence that often results in severe injuries, as cyclists are frequently thrown from their bikes or struck directly by the vehicle.

4. Aggressive Driving and Road Rage

Aggressive driving is a dangerous behavior that escalates the risk of accidents for everyone on the road, but it’s particularly threatening to cyclists. Some examples of aggressive driving include:

• Tailgating: When drivers follow cyclists too closely, they reduce their ability to react if the cyclist needs to stop suddenly or maneuver around road hazards.
• Cutting Off Cyclists: Some drivers deliberately cut off cyclists by making abrupt lane changes, leaving the cyclist little room to safely maneuver.
• Honking or Intimidation: Drivers may honk excessively, shout, or even make hostile gestures toward cyclists. This aggressive behavior can intimidate cyclists and lead to mistakes or falls.

Aggressive driving is often a result of road rage or frustration, but it can be deadly for cyclists. Such behavior shows a blatant disregard for cyclist safety, making it a serious form of negligence.

5. Driving Under the Influence: Impairment Increases Risk for Cyclists

Driving under the influence of alcohol or drugs is a form of negligence that puts cyclists at extreme risk. Impaired drivers have decreased reaction times, impaired judgment, and a reduced ability to stay focused on the road, all of which can lead to:

• Inability to Recognize Cyclists: Impaired drivers often fail to notice cyclists or misjudge their position and speed, leading to dangerous collisions.
• Poor Decision-Making: Alcohol and drugs can impair judgment, leading drivers to take unnecessary risks, speed, or ignore traffic signals.
• Delayed Reaction Time: Alcohol and drugs slow reaction times, which can prevent drivers from stopping or swerving in time to avoid a collision with a cyclist.

Driving under the influence is one of the most reckless forms of negligence, and it often leads to tragic outcomes. Cyclists struck by impaired drivers are especially vulnerable to severe and fatal injuries.

Legal Options After a Bicycle Crash in San Diego

1. Filing a Personal Injury Claim

If a negligent driver injures you, you may recover compensation for medical treatment, lost wages, ongoing care, and pain and suffering. Building a strong claim requires evidence like photos, police reports, medical records, and witness statements.

2. Uninsured Motorist (UM) Coverage

In hit-and-run incidents or situations involving uninsured drivers, UM coverage under your auto insurance policy can provide critical financial relief.

3. Government Claims

If unsafe infrastructure—like missing bike lane protections or hazardous intersections—contributed to your crash, you may have grounds for a claim against the city or county. These claims require filing a claim within six months.

4. Wrongful Death Litigation

When a cyclist’s death results from a driver’s negligence, surviving family members may pursue a wrongful death lawsuit for accountability and damages.
