This paper exploits the dramatic increase in tickets during the Click-it-or-Ticket campaign to identify the causal impact of tickets on accidents using data from Massachusetts.
Generalization may be fair to question.
This paper examines whether traffic tickets affect road safety as measured by motor vehicle accidents. A naïve OLS regression of accidents on tickets suggests that there is no impact of tickets on accidents. However, an analysis using exogenous variation in the number of tickets issued to identify the causal effect of tickets on road safety gives rise to distinctly different results – tickets in fact lead to fewer motor vehicle accidents. Further, tickets help to reduce non-fatal injuries stemming from motor vehicle accidents. In addition, the heterogeneous impact of tickets suggests that there is scope for intervention, for example, by allocating more resources towards traffic enforcement at night since tickets have a larger impact during nighttime. Also, females appear to be more deterred by traffic law enforcement than men. However, there do not appear to be differences in the impact of tickets on different age groups. Overall, the findings of this paper suggest that as unpopular as traffic tickets are among drivers, motorist behavior does respond to tickets.
No analysis on remote enforcement such as rural highways. IE: The increase in accidents for Montana following the posting of daylight speed limits. I wouldn't consider this conclusive evidence.

Okay, here's a source: https://www.motorists.org/blog/speed-limits-slower-safer/
Some prudent quotes:
Also, look at some safety statistics on the German Autobahn, a highway system without a speed limit:
This all comes together to show that speed limits, and hence speeding fines, only make roads more dangerous. Whereas a speed limitless road forces people to observe prevailing driving conditions and other cars' speed, the speed limit divides cars into two separate speed groups causing people to have more crashes.

Looks like he just wanted to shit on you and move on. I suspect a troll. :-/
