Failing to come to a complete stop at a posted stop sign before the required point of entry into an intersection, crosswalk, or roadway is a traffic violation commonly called running a stop sign.

The violation can happen in several ways: rolling through without fully stopping, entering the intersection before stopping, or proceeding past the stop line when visibility is blocked and stopping only after the vehicle is already too far forward. A lawful stop usually requires the vehicle to become fully motionless, then yield to any vehicle or pedestrian with the right of way before moving. In Mississippi, the duty to stop at a stop sign appears in Mississippi Code § 63-3-805. A citation can follow even when no crash occurs, because the offense is based on the driver's conduct at the sign.

For an injury claim, running a stop sign often serves as evidence of negligence and may strongly affect fault decisions after a wreck. If the driver who failed to stop caused a T-bone collision, pedestrian impact, or chain-reaction crash, the violation may support a claim for damages. Photos of the intersection, crash reports, camera footage, skid marks, and witness statements often matter.

Mississippi follows pure comparative negligence under Miss. Code § 11-7-15, so compensation can be reduced by the injured person's share of fault rather than barred completely. During Gulf Coast storms or heavy tourist traffic on US-90 near Biloxi, poor visibility and congestion may explain conditions, but they do not cancel the legal duty to stop.
