Accidents involving dangerous roadways may involve negligence from the governmental entity responsible for maintaining the area. However, these accidents can be challenging to pursue because of the interplay of various state and federal laws regarding governmental immunity. Washington D.C. allows certain personal injury lawsuits against the government; however, there are exceptions when a discretionary governmental function is at issue. In those cases, the courts will inquire if an action is discretionary and whether the function poses a threat to the quality and efficiency of government liability.
