In Hoenisch v. Department of Transportation, Bureau of Driver Licensing, 567 Pa. 89, 785 A.2d 969, 971 (2001), the Supreme Court, addressing whether North Carolina's 0.08% blood-alcohol threshold for being considered driving while intoxicated was substantially similar when Pennsylvania had a 0.10% blood alcohol threshold, held that its "per se" drunk driving offense of driving with a 0.08% blood- alcohol level was sufficiently similar because the "per se" threshold merely represented a legislative decision that such level of intoxication constituted conclusive evidence of an appreciable impairment, and state laws needed only to be of a substantially similar nature. Before Act 24 amended 75 Pa. C.S. 3731(a)(4)(i) and (a.1)(1)(i) (related to drunk driving), no offense occurred or penalty was imposed if a licensee was driving in Pennsylvania with a blood-alcohol level of less than .10%. Act 24, however, amended Section 3731, making it an offense to operate a motor vehicle with a blood alcohol level at 0.08% but less than 0.10%. Within an instant, Section 3731 was then replaced by 75 Pa. C.S. 3802(a).
