NHTSA data shows that Louisiana drivers are sometimes involved in fog-related accidents. Fog reduces the visibility of drivers, obscures what they see and diminishes contrast, making it hard for them to perceive speed and depth. Additionally, high beams are meant to help under low-visibility circumstances but only bounce off of fog to create even more challenging conditions.
From 1990 to 2012, there was a general decline in the number of fatalities in fog-related accidents, which is consistent with an overall decline in nationwide fatal crashes. However, the risk of fog-related collisions is greater in states that experience more fog formation.
According to data from the NHTSA's Fatality Analysis Reporting System, there were 18,295 crashes in Louisiana during the same period, and 400 of those involved fog. This is a relatively low number of fog-related accidents compared to the states with the highest numbers, which were Texas with 1,062 and California with 1,001. On the other end of the spectrum, Hawaii had the lowest number of fog-related crashes with just seven. The next to lowest numbers were in the District of Columbia with 14 and Nevada with 20.
The crash data also shows that fog-related accidents are most prevalent from December to February and least prevalent from June to August. Most of these collisions happen between midnight and noon, when fog is more likely to form. Driver ages that account for the highest proportion of fatal fog-related crashes are those between 20 and 29. Teens account for the second-highest proportion.
Fog-related collisions may be the result of negligence if the drivers are found to have failed to reduce their speed to take the weather conditions into account. A person who is injured in such an accident may want to meet with an attorney in order to determine the best way to seek compensation.
