I try not to drive after drinking kava, but if I have to or it ends up in my plans, I'll only do so with a nice mellow Hawaiian kava like HKC Hiwa or Mahakea, something that is just a mellow body relaxation at most. In fact, the mellow kavas probably make me a much better driver, as driving normally makes me nervous and over-corrective, and kava will demolish that. Just remember how different kavas hit you, and if you find you need to drive somewhere, stick with a mellow, light kava.
