¶2 Thomas Joseph Mahan (Mahan) appeals from a November 13, 2018 Thirteenth

Judicial District Court for Yellowstone County decision affirming his June 12, 2018 Justice

Court conviction of misdemeanor Driving Under the Influence of Alcohol pursuant to

§ 61-8-401(1)(a), MCA. We affirm.

¶3 Around 1:00 a.m. on August 4, 2017, Deputy Aaron Harris (Harris) of the

Yellowstone County Sheriff’s Office was parked in a closed-down gas station on

Highway 87 East in Billings when a tow-truck driver pulled up to Harris’s vehicle and

related that a gray pickup truck was parked in the middle of Cerise Road with the driver

apparently passed out. At its closest, Cerise Road is about half a mile’s drive from where

Harris was parked. The tow truck driver provided his name and contact information to

Harris and, referring to the driver of the gray pickup truck, stated, “I don’t know if he needs

help, or . . . .” Harris responded, “Okay, I’ll go check on him.”

¶4 Harris was on the phone with another deputy and, as he pulled out of the lot and

proceeded towards Cerise Road, requested that the other officer also drive toward Cerise

Road. About 20 seconds later, a gray pickup truck, driven by Mahan, passed Harris going

in the opposite direction. Harris turned around and followed this vehicle, which soon came

2 to a stop at a red light. Harris radioed the license plate information to dispatch. Harris

testified that he observed a liquid running down the truck’s rear bumper which was later

determined to be vomit.

¶5 When the stoplight turned green, the truck made a left turn. Harris testified that the

vehicle accelerated rapidly and crossed the fog line, or painted lane markers, and appeared

to be weaving before approaching another traffic light. In the video recording from

Harris’s dash cam, the truck can be heard accelerating as it leaves the camera’s field of

view for several seconds before Harris’s vehicle also completes the left turn and brings the

truck back into frame as it approaches the next traffic light. While visible in the frame,

Mahan does not cross the dashed line dividing lanes or the fog line, which closely abuts a

curb, or appear to be weaving.

¶6 Mahan then made another left turn at the green traffic light, entering an interstate

entrance ramp. Harris testified that the Mahan accelerated rapidly up the entrance ramp

and appeared to be weaving within his lane and crossing the painted lane marker several

times. Mahan is outside of the frame of Harris’s dashboard camera for approximately five

seconds after making the left turn. When Harris completes the turn and brings the truck

back into the camera’s view, Mahan can be seen proceeding up the entrance ramp without

crossing lane markers or noticeably weaving. Once on the interstate, the video shows

Harris close the distance to Mahan’s truck.

¶7 The speed limit on this section of highway is 65 miles per hour. Harris testified

that, using both his speedometer and his radar, he “paced” Mahan’s truck traveling at

74 miles per hour. He then clarified that he does not have same direction radar capability

3 and that he essentially uses the radar to verify the accuracy of his own speedometer.

Harris’s dashboard camera is an Arbitrator system that can use GPS to calculate the speed

of Harris’s vehicle and display it on the video playback. The recorded video shows Harris

close the gap to Mahan’s truck over the course of approximately 26 seconds after leaving

the intersection, then follow the truck closely for approximately seven or eight seconds

before activating his emergency lights. The Arbitrator video system displays no speed

readouts between when Harris merged onto the interstate—when it shows 51 miles per

hour—and when he activates his emergency lights, approximately 20 seconds later. At

that point, the Arbitrator recording system displays Harris’s speed as 70 miles per hour.

¶8 As he approached Mahan’s truck, Harris stated, “The reason I’m stopping you is

this is a 65 in here. I just paced you going 74.” The traffic stop eventually led to Mahan’s

arrest for driving under the influence of alcohol. It is undisputed that Mahan’s truck was

not the same truck with the passed- out driver on Cerise Road that was reported by the tow

truck driver.

¶9 Mahan was charged in Yellowstone County with the misdemeanor of Driving Under

the Influence of Alcohol, First Offense, in violation of § 61-8-401(1)(a), MCA. The

Yellowstone County Justice Court denied Mahan’s motion to exclude the evidence

obtained from the stop, determining that Harris had a sufficiently particularized suspicion

to justify the stop. The Justice Court’s conclusion rested on its determination that Harris

had corroborated the tow-truck driver’s report by finding Mahan’s truck “substantially as

described” and through his testimony that he had observed the vomit-adorned truck make

unusually rapid accelerations, weave across lane markers, and speed. After a jury trial,

4 Mahan was found guilty of misdemeanor Driving a Motor Vehicle Under the Influence of

Alcohol. The District Court affirmed, determining that Harris was justified in conducting

a traffic stop on the basis of Mahan’s alleged speeding.

¶10 This Court reviews lower court rulings that are appealed to a district court de novo,

as if the appeal had originally been filed with this Court. State v. Ellison, 2012 MT 50, ¶ 8,

364 Mont. 276, 272 P.3d 646; State v. Akers, 2017 MT 311, ¶ 9, 389 Mont. 531, 408 P.3d

142. When reviewing rulings on a motion to suppress, we determine whether the lower

court’s factual findings were clearly erroneous and whether the interpretation and

application of law was correct. State v. Wilson, 2018 MT 268, ¶ 21, 393 Mont. 238, 430

P.3d 77 (citation omitted). A lower court’s finding of the existence of particularized

suspicion is a question of fact. City of Missoula v. Moore, 2011 MT 61, ¶ 10, 360 Mont.

22, 251 P.3d 679. A finding is clearly erroneous if it is not supported by substantial

evidence, the court misapprehended the effect of the evidence, or the review of the record
