Did the offcier show specific and articulable facts for the stop?

An officer must show specific articulable facts for reasonable suspicion to justify a traffic stop and not just make a conclusory statement that a defendant was violating a traffic law. Ford v.

Texas courts have routinely held that a vehicle crossing into another lane does not necessarily provide probable cause for the seizure. See, e.g, Fowler v. State, 266 SW3d 498 (Tex.App.--Fort Worth 2008). Many other courts have reached the same conclusion under similar facts. See, e.g.,Hernandez v. State, 983 S.W.2d 867, 871 (Tex.

It's not illegal if it doesn't trigger the specific case law above. It's not illegal if there's not enough information and it was not made unsafely.
