$1,250 for going 78mph on an interstate highway.
That should about do it for anyone who still believed traffic enforcement has anything to do with safety or serves any purpose other than aggressive revenue grabbing. Heck, the legislators even admitted it this time.
The part of the Beltway that passes through Alexandria, crosses the river and arrives in Maryland frequently slows to 0MPH from about 3PM to 7PM on a daily basis.
I assure you this penalty simply does not apply to the Beltway.
