How Do Weather Conditions Affect a Car Accident Claim?

In Western Washington, driving in challenging weather is a part of life. From the slick, oil-covered roads during the first autumn rain in Tacoma to the treacherous black ice on a winter morning, drivers are expected to adapt. But when an accident happens during a downpour or a snowstorm, it raises a complex question: How does the weather affect who is at fault?

Often, the at-fault driver will try to use the weather as an excuse for their actions. They might say, “I couldn’t stop in time because the roads were wet,” or “I skidded on a patch of ice that wasn’t my fault.”

It is a critical legal principle, however, that weather conditions are an explanation for a crash, not an excuse for negligence. While the weather is a factor in how an accident happens, the law almost always assigns fault to the driver who failed to safely operate their vehicle for those specific conditions.

Useful Information for You: In a Nutshell

• Weather is Not an Excuse: A driver cannot blame the rain or ice for causing an accident. Fault is still determined by driver negligence.
• Drivers Have a Duty to Adapt: Washington’s “basic speed law” requires drivers to operate at a speed that is “reasonable and prudent” for the current conditions, which is often slower than the posted speed limit.
• Following Too Closely is a Key Factor: In rain or snow, a driver who rear-ends another vehicle is almost always at fault for not leaving enough following distance to stop safely on a slippery surface.
• Evidence is Still Critical: Documenting the weather conditions with photos of the scene can be important evidence to show how the other driver should have been behaving.
• Government Liability is Rare: While a government entity can sometimes be held liable for failing to maintain a known hazardous road condition, these cases are very difficult to prove.

The Driver’s Duty: The “Basic Speed Law”

The foundation of fault in a weather-related accident is Washington State’s “basic speed law” (RCW 46.61.400). This law states that no person shall drive a vehicle at a speed greater than is reasonable and prudent under the conditions.

This means the posted speed limit is a maximum, not a suggestion. If it’s raining heavily, foggy, or the road is icy, a driver has a legal duty to slow down to a speed that is safe for those specific hazards. A driver who causes a crash by driving the speed limit on a sheet of ice can, and usually will, be found negligent for driving too fast for the conditions.

How Weather Affects Common Accident Types

Rear-End Collisions:

In rain or snow, the stopping distance for a vehicle is significantly increased. A driver has a duty to increase their following distance to account for this. If a driver rear-ends you on a wet road, they are almost certainly at fault for following too closely. The excuse “I couldn’t stop in time” is actually an admission that they were not driving prudently for the conditions.

Loss of Control Accidents:

If a driver loses control on a curve, hydroplanes, and slides into your lane, they are generally responsible. They failed to adjust their speed to a level that would allow them to maintain control of their vehicle in the hazardous weather.

Can Anyone Else Be at Fault? The Rare Exception of Government Liability

While the driver’s duty is primary, there are rare instances where a government entity (like WSDOT or the City of Tacoma) could be held partially liable. This is not for a temporary weather event, but for a known, recurring hazard they failed to address. For example:

• An area of road with poor design and inadequate drainage that is known to flood dangerously every time it rains.
• A bridge overpass that is known to freeze before other road surfaces, for which there are no warning signs.

Proving government liability in these cases is extremely difficult, as you must show the agency knew about the specific hazard and had a reasonable time to fix it but failed to do so.

Bad weather doesn’t cause accidents; negligent drivers do. The law requires every driver to be a responsible and active participant in road safety, and that responsibility increases dramatically when the weather turns sour. If you’ve been injured in an accident in the Tacoma area that you believe was caused by another driver’s failure to adapt to the weather, search the Car Accident Lawyer Directory Tacoma. Compare profiles and read real client reviews to find a trusted local attorney who understands how to prove negligence, even in a storm.
