What color is commonly used to mark evidence at a crash scene?

Yellow is commonly used to mark evidence at a crash scene because it is highly visible and easily recognizable. The use of yellow is standard in many jurisdictions for traffic-related investigations, which helps ensure that all officers and investigators can quickly identify the locations of critical evidence. This high visibility allows for better communication and documentation during the investigation process, as yellow markers stand out against various backgrounds and can be spotted from a distance.

Other colors, while they may be used in specific contexts or jurisdictions, do not have the same standardized association with evidence marking in crash scenes. For example, red might be used for other specific purposes, such as hazard markings, but it does not carry the same universal recognition for evidence as yellow does. Thus, yellow becomes the preferred choice for marking evidence at accident sites to maintain uniformity and clarity in traffic crash investigations.
