Touche, Sir. 10% is a general rule of thumb for the open highway in Tx (officer discretion, if you please), but you can absolutely get a citation for 1 MPH over the posted limit (especially in small towns, residential areas, or school zones/work zones). Growing up in Galveston County we knew a couple LEOs, & the rule of thumb back then was 5 MPH over + 1 (five over was expected, plus one MPH grace for calibration issues either with their radar or your speedometer). At least that's how it was applied in our little town back in the '80s.ScottDLS wrote:The law is 10% over?

I haven't had a speeding ticket in over 15 years, but the last time I went to defensive driving class, everyone was there for speeding, and everyone was 11 mph or more over.
ETA: This is my understanding; Smokey beat me to a response above, & he's an LEO so his reply holds more weight.
