Law enforcement officers may stop a vehicle when they have reasonable suspicion to believe that the driver has violated a traffic law. See State v. Styles, 362 N.C. 412, 415, 665 S.E.2d 438, 440 (2008). This rule applies regardless of whether the offense is a felony, misdemeanor or infraction, and regardless of whether the officer has an ulterior motive for making the stop. See Whren v. United States, 517 U.S. 806 (1996).
The expansive scope of this authority is well-recognized. Some have argued that the “heavy and minute” regulation of vehicles renders “total compliance with traffic and safety rules nearly impossible.” Whren, 517 U.S. at 810 (citing petitioner’s argument to this effect). Thus, they say, “a police officer will almost invariably be able to catch any given motorist in a technical violation.” Id.
A quick review of criminal case law provides some support for that notion. Law enforcement officers frequently substantiate more serious criminal conduct through citizen encounters that begin with a simple traffic stop. See, e.g., State v. Heien, 366 N.C. 271 (2012) (defendant stopped for ostensible brake light violation and arrested for drug trafficking); State v. Dickenson, __ N.C. App. ___ (April 15, 2014) (unpublished) (defendant stopped for failure to wear seatbelt and arrested for drug trafficking); State v. Franklin, __ N.C. App. __, 736 S.E.2d 218 (2012) (defendant stopped for seatbelt violation and arrested for drug crimes); State v. Townes, ___ N.C. App. ___, 734 S.E.2d 139 (November 6, 2012) (unpublished) (defendant stopped based on DMV insurance stop and arrested for carrying a concealed weapon and felony drug crime); State v. Osterhoudt, ___ N.C. App. ___; 731 S.E.2d 454, 460 (2012) (defendant stopped after officer observed him cross double yellow line while making right turn and arrested for DWI).
My top three little-known and oft-ignored traffic rules are below.
1. Stopping behind the white line. When a stop sign or traffic signal requires a vehicle to come to a complete stop at an intersection or some other place in the road, the vehicle must stop at the appropriately marked stop line, if there is one. See G.S. 20-158(b)(5); (c)(5). A driver who stops his or her vehicle before entering an intersection or proceeding past the sign or signal—but beyond a marked stop line—has committed a traffic violation for which he or she may be stopped. I always stop before the sign or signal, but I seldom focus on whether my front tires are over the line, unless there is a marked crosswalk. I’m sure I’m not alone.
2. The two-second rule. G.S. 20-152 prohibits the driver of a motor vehicle from following another vehicle more closely than is reasonable and prudent. The State Highway Patrol recommends that motorists keep at least one car length interval per 10 miles per hour of speed. So, if the car in front of you is traveling 60 miles per hour, you should remain six car lengths behind it. The state DMV handbook advises drivers to follow the “two-second rule,” which requires drivers to allow two seconds between the time the vehicle ahead of you passes a given point and the time your vehicle reaches the same point. I’m going to test this one out on I-40 on my way home. If I don’t, I’m subject to being stopped for following too closely in violation of G.S. 20-152. In United States v. Mubdi, 691 F.3d 334, 337 (4th Cir. 2012), cert. granted, judgment vacated on other grounds, 133 S. Ct. 2851, 186 L. Ed. 2d 902 (U.S. 2013), the NC Highway Patrol officer who stopped the defendant explained that he relied on the two-second and car-length rules in determining whether a driver had violated G.S. 20-152.
3. Signaling before changing lanes. G.S. 20-154 requires drivers on streets, highways and public vehicular areas to signal before starting stopping or turning from a direct line if another vehicle may be affected. Changing lanes is a turn requiring a signal under this provision. See Sass v. Thomas, 90 N.C. App. 719 (1988). An officer may not make an investigatory stop of a vehicle for failing to use a turn signal unless a reasonable officer would have believed that the defendant’s failure to use the turn signal might have affected the operation of another vehicle. See State v. Ivey, 360 N.C. 562 (2006) (finding that no violation of G.S. 20-154(a) occurred when a defendant failed to use his turn signal before making a right hand turn at an intersection, which was the only legal movement he could make). Our state appellate courts have concluded that a defendant’s failure to signal before changing lanes when driving immediately in front of another vehicle may affect the operation of the trailing vehicle, see State v. Styles, 362 N.C. 412 (2008), as may turning right in medium traffic while travelling about 100 feet in front of another car, see State v. McRae, 203 N.C. App. 310 (2010). My experience suggests that many, many people do not know about, or possibly know, but do not care to comply with, this rule.
