Washington, D.C. is unlike any other personal injury market in the country. Federal agencies, Metro transit systems, government contractors, and major hospital networks all operate within a compact, high-traffic environment. When serious accidents happen here, the cases often involve powerful defendants and complex jurisdictional rules.
D.C. is also one of the few places in the country that still follows a strict contributory negligence standard. That single rule changes everything. If an injured person is found even slightly at fault, recovery can be barred entirely. Because of that, trial preparation and liability strategy are critical from day one.
