Arizona v. Johnsongreen2 sentences2026As previously observed: “the risk of a violent encounter in a traffic-stop [J-74-2025] - 28 setting stems not from the ordinary reaction of a motorist stopped for a speeding violation, but from the fact that evidence of a more serious crime might be uncovered during the stop.” Johnson, 555 U.S. at 331 (internal quotation marks omitted). 2025As the United States Supreme Court has observed, the risk of a violent encounter in a traffic-stop setting “stems not from the ordinary reaction of a motorist stopped for a speeding violation, but from the fact that evidence of a more serious crime might be uncovered during the stop.” [Wilson, 519 U.S. at 414 ]. “[T]he motivation of a passenger to employ violence to prevent apprehension of such a crime … is every bit as great as that of the driver.” [Id.] Johnson, 555 U.S. at 331-32 . | 2 | 4 |

Martin v. Commonwealth, Department of Transportation, Bureau of Driver Licensinggreen2 sentences2006In the dissent's view, Officer Sollenberger lacked statutory authority to arrest appellant because the conduct the officer witnessed in his own jurisdiction did not establish a speeding violation, since the officer did not clock appellant's vehicle for the requisite statutory distance, and the "other driving and conduct of [appellant] . . . took place outside his primary jurisdiction, where he lacked authority to make an arrest." Therefore, the dissent concluded, appellant's refusal to submit to chemical testing was a "legal nullity" and the Implied Consent Law "does not apply."

Martin v. Dept. of Transp.

Commonwealth v. Monosky
green
2 sentences1989In support of its position that a police officer’s estimation of speed, absent an exact measurement from a speed timing device, is legally sufficient to establish a speeding violation, the Commonwealth cites Commonwealth v. Monosky, 360 Pa.Super. 481 , 520 A.2d 1192 (1987). 1989In support of its position that a police officer’s estimation of speed, absent an exact measurement from a speed timing device, is legally sufficient to establish a speeding violation, the Commonwealth cites Commonwealth v.

1 sentence1974This burden, however, arises after the Commonwealth has made out a prima facie case by producing the records of conviction received by the department from the magistrate and the secretary’s records compiled therefrom which justified the suspension: Virnelson, supra.
