Which lanes get the most speeding tickets

Sometimes my doctoral research turns up interesting data. Last time it was Texas’s worst speed traps.

This time, I found that a small portion of Dallas County Sheriff and Constable* traffic tickets indicated which lane a speeding citation came from. I teased out that data and got this:

Note that this is mainly for freeways.

Lesson learned? Stay out of the left lane to avoid speeding tickets.

*Constable traffic patrols were disbanded a few years ago, but my dataset includes their activity.
