Problem with the Letter “O” and the Number “0” on Colorado License Plates
An unusual problem has arisen in the state of Colorado: automated license plate reading systems confuse the letter “O” with the number “0.” This has led to erroneous speeding tickets, unpaid toll road fees, and unjustified traffic stops by police.
Imagine a situation: you receive a speeding ticket in a city you have never visited. Worse yet—when a ticket is issued for a vehicle that does not even belong to you. This is exactly what Colorado residents face as authorities try to resolve the issue by redesigning license plates. At the same time, a question arises: shouldn’t the cameras themselves be criticized, since they created this problem?
How Did the Confusion Arise?
State officials acknowledge that automatic license plate readers cannot clearly distinguish the letter “O” from the number “0” on some plates. This has resulted in erroneous speeding tickets, toll charges, parking citations, and numerous stops of innocent drivers. It remains an open question why the officers involved in these stops could not read the license plates themselves.
At first glance, this may seem like a design problem with the license plates. In 2018, Colorado switched to a format with four letters and two numbers, placing letters and numbers on one side of the plate. This has created situations where “O” and “0” can appear in similar positions.
People Are Not to Blame, the Problem Lies in the Technology
However, the problem is not with the people. According to an investigation by 9NEWS, the confusion primarily arises from automated license plate reading systems used by municipalities, toll road operators, parking enforcement companies, and law enforcement agencies.
In a recent case, a driver received a ticket from a camera located in a city two hours away from his home, even though he was driving a completely different vehicle from the one in the photo. The cause was again a reading error due to a single character.
Authorities Change Plates, Not Cameras
To solve the problem, Colorado authorities did not improve the cameras. Instead, they stopped issuing license plates with the letter “O” in the fourth position. If you have an older plate with the letter “O” in that position, this will not help you.
The Department of Motor Vehicles also changed the font on license plates to better distinguish “O” from “0” and states that it is working with institutions to calibrate their readers. Thus, authorities effectively acknowledge that the technology has limitations. However, instead of forcing all license plate reading systems to improve, the state adjusted the issuance of future plates. For drivers who have spent years disputing toll bills or fines due to incorrect plate readings, this may seem like treating symptoms rather than the cause.
This situation raises an important question about how much we trust automated systems in the realm of traffic violations. Instead of demanding higher accuracy from technologies, the state decided to change the rules for issuing plates. This sets a precedent where technical shortcomings are compensated at the expense of citizens’ convenience rather than through system improvements. Perhaps the next step should be a review of how these systems make decisions about fines, because errors in a single character should not lead to such serious consequences for innocent people.
