State law has mandated seat belt use by North Carolina motorists for more than thirty years. The seat belt law has, however, changed a bit over time. As a result, not everyone is clear on who is covered, what is required, and what the penalties are for violations. This post covers the particulars of North Carolina’s seat belt requirements and addresses three common areas of confusion.

HGN, the Rules of Evidence and Suppression Hearings
True or False: An officer does not have to be qualified as an expert to testify about horizontal gaze nystagmus in a hearing on a motion to suppress in an impaired driving case.

When May Evidence of HGN Come on Down . . . or In?
The question I am most frequently asked these days is some version of the following:
May a law enforcement officer trained in administering the HGN test testify at trial about a defendant’s performance on the test if no other expert testifies about the relationship between nystagmus and impairment by alcohol?
While the answer obviously is either yes or no, there is more than one way to analyze the issue. Since today is Thursday, I’m going to throw it back to Bob Barker and the Price is Right and give you two showcases to consider.

Does State v. Ashworth Place Factors Over Substance?
The court of appeals reversed a defendant’s DWI conviction yesterday in State v. Ashworth, __ N.C. App. __ (August 2, 2016), on the basis that the trial court plainly erred in holding that the driver’s license checkpoint at which the defendant was stopped was appropriately tailored and advanced the public interest. Unlike some checkpoint cases in which you can see the trouble coming in the recitation of facts, Ashworth is a pretty routine checkpoint case. Two officers with the State Highway Patrol set up the checkpoint to look for driver’s license and other traffic violations. The highway patrol had a checkpoint policy that the officers followed. A supervisor approved the checkpoint. The defendant admitted that he had been drinking almost immediately after he stopped at the checkpoint. So where did the trial court go wrong?

What’s the Latest on Mopeds?
Laws governing the operation of mopeds have changed significantly in recent years. Mopeds now must be registered before they may be driven on state roadways, and the owner of the moped must have insurance. An overview of the current legal requirements for moped operation is set forth below.

Breath Tests Incident to Arrest are Reasonable but Prosecution for Refusing a Blood Test Goes Too Far
The U.S. Supreme Court waded into the murky waters of implied consent law this term in Birchfield v. North Dakota. The opinion it issued last week clarified important aspects of the relationship between chemical testing for impairment and the Fourth Amendment, but failed to distill a coherent theory of implied consent. Here’s what we know after Birchfield:
- Warrantless breath testing of impaired driving suspects is permissible under the Fourth Amendment as a search incident to arrest. A person who refuses to submit to such testing may be subjected to sanctions ranging from license revocation to criminal prosecution.
- Warrantless blood testing of impaired driving suspects is not permissible under the Fourth Amendment as a search incident to arrest. Thus, a warrant or a suspect’s consent is required to conduct such testing. A person who refuses to submit to such testing may not be criminally prosecuted for that refusal.

Amendments to Notice and Demand Provisions for DWI Cases
No legislative session would be complete without amendments to the state’s DWI laws. The 2016 short session upholds this tradition by amending the procedures that govern the admissibility of chemical analyses in impaired driving trials in district and superior court.

The Right to Life, Liberty, and Fifteen Additional Days to Renew Your Registration
Before I became a lawyer, I finished everything ahead of time. Term paper? Completed two weeks early. Trip? Packed a week in advance. Taxes? Filed in February. Alas, those days are nearly two decades behind me. Now I squeak in just under the wire with everything I do—including my weekly blog posts. I could proffer a host of reasons, but don’t think I need to so long as I meet the deadline. My modus operandi may explain why I was particularly troubled by the traffic stop in State v. Baskins, ___ N.C. App. ___ (May 17, 2016).

A political science professor, a civil rights lawyer and a police chief walk into a classroom . . .
I haven’t figured out the punch line to this joke. It was my opening line for a traffic stops session taught last month in the special topics seminar, Race Issues in the Courts, by UNC Professor Frank Baumgartner, Southern Coalition for Social Justice Staff Attorney Ian Mance, and Fayetteville Police Chief Harold Medlock. One reason that it is hard to finish the joke is that these three were on the same page, which is somewhat surprising given the roles they occupy.
I immediately thought of that talk yesterday when I saw this News and Observer photograph of United States Attorney General Loretta Lynch standing next to Chief Medlock. Lynch traveled to Fayetteville as part of her nationwide community policing tour. She chose Fayetteville in part because of the work the presenters discussed at our April conference.
