Pedestrian Fatality Charge Ends in Acquittal After Defense Proves Collision Was Unavoidable

Case Overview

A driver who struck and killed a pedestrian while proceeding through a green light was charged with causing death through a traffic accident. Although a police review of the vehicle's dash camera showed the driver had been speeding, the defense obtained a forensic appraisal establishing that the collision could not have been avoided even at the posted speed limit. The court acquitted the driver.

Background

The client was traveling straight through an intersection on a green signal when a pedestrian entered the roadway against a red signal. The client did not see the pedestrian in time, and the pedestrian died from the collision. During the police investigation, an analysis of the dash camera footage showed that the client had been traveling roughly fourteen kilometers per hour over the sixty kilometer-per-hour speed limit.

The family of the deceased could not be reached, which left no realistic opportunity to reach a settlement before trial. Because the speeding was objectively documented on the dash camera, it could not simply be denied. From the outset, the case appeared to weigh heavily against the driver.

Criminal Allegation

The client was indicted for causing death through a traffic accident under the Act on Special Cases Concerning the Settlement of Traffic Accidents, and the matter proceeded to trial. Under Korean law, a traffic accident that causes death can carry a sentence of up to five years' imprisonment or a fine of up to twenty million won. A fatal accident in which speeding has been proven, and in which no settlement with the family has been reached, begins from a difficult position.

Key Legal Issues

The central question was not whether the driver had been speeding, but whether the speeding caused the death. Speeding is itself a violation, but holding the driver responsible for the fatality requires proof of a causal link between the excessive speed and the collision. If the accident would have occurred even at the posted limit, the speed could not be the basis for responsibility for the death.

The dash camera and roadway CCTV showed that the pedestrian had crossed against a red signal and that the driver had proceeded on a green signal. This raised a genuine question about whether the driver was at fault at all.

Defense Strategy

The defense reviewed the dash camera footage frame by frame and identified a section in which the headlights of vehicles in the oncoming lane created a backlight that obscured the pedestrian. This supported the argument that the driver had not failed to look, but had been unable to see the pedestrian under the prevailing conditions.

At trial, the defense requested an accident reconstruction appraisal from the National Forensic Service and carefully framed the question the appraisal was to answer: whether the collision could have been avoided if the driver had been traveling at the speed limit. Because the appraisal's answer depends on how the question is posed, drafting that question accurately was essential.

The appraisal concluded that even if the driver had observed the speed limit, the collision could not have been avoided. On that basis, the defense argued that the fact of speeding and the question of causation were separate matters, and that criminal responsibility could be imposed only if the prosecution proved the speeding had caused the death.

Outcome

The court acquitted the client, finding that there was no way for the driver to have avoided the accident. The speeding remained in the record, but the court held that it could not, by itself, support responsibility for the death. Even without a settlement with the family, contesting the question of fault itself changed the outcome.

What This Case Shows

The result turned on the timing and manner of the appraisal request. By first using the dash camera to identify the precise point to contest, and then carrying that point into a carefully worded question for the court-ordered appraisal, the defense was able to turn the appraisal's conclusion directly into the basis for acquittal. In a fatal traffic accident, the outcome can depend heavily on the available video evidence and how the forensic question is framed, which is why experienced criminal defense representation is decisive at every stage in Korea.
