San Diego Dangerous Roads Injury Attorney

Auto Accidents Caused By Defective & Dangerous Roads

More than 30,000 people are killed and millions more are injured in car accidents every single year. One of the leading causes of these accidents is road defects. According to statistics, this issue causes an estimated 13,500 crashes annually. This includes the design of the road, issues with road signs and signals, obstructed views, and more.

State agencies and local municipalities are obligated to keep roads maintained and functional. If a dangerous or defective road caused your accident, you may be able to seek compensation from one of these parties. The McClellan Law Firm has experience handling all types of auto accident claims; let us use this experience to your advantage.

Examples of Common Road Defects

A road is "defective" when its design endangers safe drivers. For example, a road should give consistent messages to drivers. Traffic signs should warn drivers of impending hazards and provide rules for safe driving, such as speed limits.

An improperly marked road might cause a motorist to drive unsafely by no fault of his or her own. In short, an unsafe road is violates its purpose: to provide a safe means for transportation. A road should facilitate safe driving in these ways:

  • Clearly marked signs with consistent messages
  • Avoid "surprises," such as an unexpected stop sign
  • Warn drivers of any potential risks or hazards
  • Keep motorists informed of unfamiliar conditions
  • Guide drivers through difficult passages

A few examples of dangerous road defects include:

  • Insufficient shoulders
  • Missing signals, signs, or guardrails
  • Overgrown roadside trees or shrubs
  • Weak bridges and other design elements, including overpasses
  • Construction zones that are not properly marked off or partitioned
  • Poorly designed intersections, on-ramps, off-ramps, and curves
  • Railroad crossings that are not properly protected or marked
  • Distressed pavement, exemplified by potholes, serious cracks, rough patches, and road edge drop-offs

Wrong-Way Crashes

Some of the most devastating accidents caused by poor road design are head-on collisions caused by drivers traveling the wrong way on the road. In a Highway Special Investigation Report (PDF) put together by the National Transportation Safety Board (NTSB) that looked into the causes of deadly wrong-way driving crashes, it was found that one of the leading causes of these types of accidents was drivers entering exit ramps.

While driver-related choices like driving while under the influence of drugs or alcohol played a role in entering the wrong ramp, poor signage and poor lighting around these signs played a notable factor. The NTSB concluded that ensuring that clear signage, roadway markings and a way to see these indicators at in the dark were key factors that could help limit the number of wrong-way crashes that occur.

The NTSB also looked the designs of ramps and interchanges and found that the majority of states used one of three designs: full diamond, full cloverleaf, and partial cloverleaf.

Through their investigation, researchers noted that:

  • Full cloverleaf ramps had the lowest rate of wrong-way entries, while left-hand exit ramps had the highest rate.
  • Drivers are twice as likely to enter the wrong way on partial interchanges compared to full interchanges.
  • Exit ramps that end at two-way streets have a high rate of wrong-way entries.
  • Drivers are more likely to drive the wrong direction at interchanges that have short sight distances leading up to decision points.
  • Drivers are more likely to enter exit ramps with rounded corners than exit ramps with sharp corners due to the fact that it is easier for drivers to recognize the changing road when there is a noticeable turn rather than a more gradual change.
