This depends on what state you are licensed in and where you get caught
Driving back and forth to Arkansas 6 times in the past 6 months…I set my cruise to 5 over and had no problems whatsoever. Let my sister and my grandmother drive…both get tickets in Ohio and Tennessee for 8 and 10 over… They got tickets in an Uplander and my Malibu Maxx, my eclipse w/ 3" exhaust had no problems.
Im good with 5 over and cruising in the right or middle lane…
I just got back from GA last week. 90-79-19-77-85. I set cruise at 80 in parts where the speed limit was 70. I ran past state troopers with no issues. On the way back SC was crazy. no joke I saw atleast 20-25 ppl pulled over by SC cops, state troopers or sheriffs. I didnt see no other law enforcement the rest of the trip. in some areas where the limit was 65 I was still rolling 80-85 to keep up especially thru charlotte, SC and GA. I had big rigs rolling these speeds too. We made a side trip to AL for a family reunion. At 1 point a new F250 towing a 5th wheel backhoe trailer with another F250 on it with a riding lawn mower, 2 dirt bikes and a grill passed me like I was standing still and I had the cruise set at 75. They dont play down south.
