While road tripping through Colorado, I noticed that a lot of modern (most recent design revision) Colorado license plates...

modern plate

...had Q on them. Counting 100 plates, 49 did not have Q, 51 did. Q is an odd letter to be on more than 50% of all license plates. Why is this?

    I'm voting to close this question as off-topic because it has nothing to do with travel. – David Richerby Jul 9 '17 at 22:04

    Thanks to your image, 100% of the Colorado license plates I've seen today did not have a Q on them :) – Zach Lipton Jul 9 '17 at 22:06
  • Including the one in the question, ironically. – Burhan Khalid Jul 9 '17 at 22:08

The reason is that from 2013 till 2015, number plates in Colorado were issued in sequential order; from 001-AAQ all the way till 999-ZZQ.

From mid-2015 onwards, common sense prevailed and random combination of letters and numbers were used :-)

    Why is a random combination better than sequential numbering? – Sourav Jul 9 '17 at 23:24

    This doesn't answer the question at all. Why Q? – djechlin Jul 10 '17 at 0:49

    @djechlin it answers why there is a Q, not why Q is the letter chosen for the sequence. – corsiKa Jul 10 '17 at 1:12

    @Sourav , sequential number give away the age of the car (for locals who pay some attention), which makes it easier to identify brand new cars for stealing. – Aganju Jul 10 '17 at 1:47

    @djechlin , because Q was unused up to that point of time. Try clicking the given links. – Aganju Jul 10 '17 at 1:50
