2015: Schweikert Voted Against Requiring The NHTSA To Conduct A Study On Marijuana-Impaired Driving As Part Of A Five Year Surface Transportation Reauthorization. In December 2015, Schweikert voted against studying marijuana-impaired driving as part of a five year surface transportation reauthorization. According to Congressional Quarterly, the conference report would have "require[d] NHTSA to conduct a study on marijuana-impaired driving and whether it is feasible to establish an impairment standard that could reduce vehicle accidents caused by such driving." The underlying legislation would have "reauthorize[d] federal-aid highway and transit programs for five years, through fiscal 2020, at increased levels." The vote was on the conference report. The House approved the legislation by a vote of 359 to 65. The Senate later passed the legislation and the president later signed the legislation.
