D.C. Mun. Regs. tit. 18 § 2208
When two (2) vehicles approach or enter an intersection from different highways at approximately the same time, the driver of the vehicle on the left shall yield the right-of-way to the vehicle on the right.
The driver of a vehicle intending to turn to the left shall yield the right-of-way to any vehicle approaching from the opposite direction which is so close as to constitute an immediate hazard.
Except when directed to proceed by a police officer, a police cadet or an official traffic control device, every driver of a vehicle approaching a STOP sign shall stop at a clearly marked stop line, but if none, before entering the crosswalk on the near side of the intersection, or if no crosswalk, then at the point nearest the intersecting roadway where the driver has a view of approaching traffic on the intersecting roadway before entering the intersecting roadway.
After having stopped for a stop sign, the driver shall yield the right-of-way to any traffic in the intersection or approaching on another roadway so closely as to constitute an immediate hazard during the time when the driver is moving across or within the intersection or junction of roadways. The driver shall yield the right-of-way to pedestrians.
The driver of a vehicle approaching a YIELD sign shall in obedience to the sign, slow down to a speed reasonable for the existing conditions and, if required for safety to stop, shall stop at a clearly marked stop line, but if none, before entering the crosswalk on the near side of the intersection, or if no crosswalk, then at the point nearest the intersecting roadway where the driver has a view of approaching traffic on the intersecting roadway before entering the intersecting roadway.
After slowing or stopping for a yield sign, the driver of a vehicle shall yield the right-of-way to any traffic in the intersection or approaching on another roadway so closely as to constitute an immediate hazard during the time the driver is moving across or within the intersection or junction of roadways. The driver shall yield the right-of-way to pedestrians; Provided, that if the driver is involved in a collision with a vehicle in the intersection or with a pedestrian, after driving past a YIELD sign without stopping, the collision shall be considered prima facie evidence of failure to yield the right-of-way.
The driver of a vehicle approaching a traffic circle shall yield the right-of-way to traffic already within the circle unless official traffic control devices indicate otherwise.
The driver of a vehicle entering a freeway by way of an access ramp shall yield the right-of-way to traffic on the freeway.
The presence of an appropriate official sign underneath an official STOP sign may permit a vehicle to turn right without stopping.
The right-of-way rules set forth in §§ 2208.1 and 2208.2 shall be modified at through highways and otherwise as stated in §§ 2207 through 2210 and 2103.
A driver of any vehicle shall stop and give the right-of-way to a pedestrian who has begun crossing on the "WALK" signal to continue to the opposite sidewalk or safety island, whichever is nearest.
When official traffic-control signals are not in place or not in operation, the driver of a vehicle shall stop and give the right-of-way to a pedestrian crossing the roadway within any marked crosswalk or unmarked crosswalk at an intersection.
