Here is a list of some of the traffic enforcement "gotchas" to watch out for.
I26 from mile marker 17 to 27 in Johnson City, speed enforcement is very heavy.
West bound after exit 27 Okolona Road, the speed limit drops to 55 and the city starts making money. East bound the limit drops to 55 after exit 17. Just around the corner from m.m. 17.6 on the right side behind the bridge abutment is a very popular hunting location for the J.C. police.
Beware of the unmarked cars on this stretch. The list includes:
Grey Dodge Charger
White Mustang (I haven't seen this one for awhile)
Silver Ford Explorer (several years old)
I drove this road earlier today, and saw all of the above with the exception of the white mustang and several marked cars all running KA band radar
Jonesborough: The main road running through Jonesborough, Hwy 11/321 from Johnson City to Greeneville Has Red Light and Speed Cameras at 3 out of 4 red lights. The new light at Lowes doesn't have one yet at least it didn't this morning!
Kingsport: Red light cameras too numerous to count
Mt Carmel: A suburb of Kingsport on hwy 11W has speed cameras on their 2 mile stretch of road
I26 TN/NC border. North Carolina is justifiably proud of this beautiful stretch of road. They also seem determined to make the payments on it with speeding tickets.
IMHO the most dangerous road for bikes in this area is Hwy 11 through Greeneville. The drivers on this road seem to go out of their way to turn left in front of you. Ride with extra care on this section of road.
These are the areas that I am familiar with. Maybe some of the other local riders add to this list
