Item #: SCP-X
Object Class: Safe
Special Containment Procedures: The street intersection that houses SCP – XXXX has been blocked off from both vehicular and foot traffic, and all houses, businesses, and buildings within a one-block radius have been permanently evacuated to prevent civilian endangerment. The containment area is outfitted with security cameras, which only need to be monitored when personnel are within the vicinity.
No one may enter the containment area without receiving written permission from the current project head, which will only be granted for research purposes.
Personnel permitted to enter the containment area must be outfitted with a microphone/noise-canceling headset, and should use it to maintain radio contact with the individuals monitoring the security cameras. Personnel must obtain permission from the monitoring station before crossing the intersection, especially when motor vehicles are permitted within the containment area for research purposes.
In the event that a staff member believes he is experiencing a hallucination, he must immediately alert the monitoring station, which will then instruct him on how to leave the containment area. Instructions from the monitoring station must be followed without exception in order to ensure the safety of all personnel.
Description: SCP-X is the set of eight traffic lights on the corners of the ████-████ intersection in the town of ██████████, California.
Each traffic light is capable of creating visual hallucinations relating to traffic patterns. Survivors of each incident associated with XXXX have reported seeing a green traffic light, prompting both drivers and pedestrians to enter the intersection when they, in actuality, did not have right of way; in turn, drivers approaching from the right or left of the intersection - who also believed they had a green light - claimed to see no cars or pedestrians in the middle of the intersection until they hit them.
This hallucination caused eighteen fatal accidents in that intersection in the three-month interval before containment by the Foundation,1 leading to twenty-three deaths and another seventeen serious injuries. Surviving drivers have been questioned by local police, and none have been found to be driving under the influence of drugs or alcohol.
SCP-X's anomalous properties do not seem to affect individuals viewing video footage of it, and disconnecting traffic lights from the power grid have not prevented the hallucinatory effects from occurring. Security footage of the intersection taken from two nearby establishments - a bakery at 328 N ████ St and a jewelry store at 8712 W ████ Ave - has shown that the traffic lights in the intersection do in fact follow the pattern mandated by the county's Department of Traffic and Public Safety; during each accident, green traffic lights permitted only either north-south or east-west traffic at any given moment, despite drivers' reports to the contrary.
Each day, at exactly 1:33pm, a chalk drawing appears on the sidewalk at the north-eastern corner of the intersection. It says 'Go Green!' in green chalk, with the letter 'O' in 'Go' represented by a cartoon drawing of the planet Earth, which proceeds to grow larger over the next four minutes. Once the Earth chalk drawing is as wide as the sidewalk, it explodes into colorful confetti. The term 'awcy?' then appears in purple chalk and flashes every two seconds for the next three minutes, after which it disappears. As such, it is suspected that a member (or members) of the anartist group 'Are We Cool Yet?' has managed to tamper with the physical laws controlling light in the vicinity in order to impart a fatal mandate encouraging individuals to lead more eco-friendly lifestyles.
An ongoing investigation is attempting to identify and apprehend the individual(s) responsible.2. Since the ability to create and manipulate such illusions could have profound practical applications, it is recommended that the Foundation continue to study SCP-XXXX.
