To increase adoption of new technologies many scholars suggested policies including information and trialling. This study reports on a randomised control trial (RCT) investigating whether information on and experience with Battery Electric Vehicles (BEVs) can alter knowledge and purchase intentions. A large (N = 4149) random sample of conventional car holders was randomly divided into three groups: one receiving comprehensive information on BEVs, another getting the same information plus an actual multi-day test drive with a BEV, and a control group without any intervention. For the first time, information and test-driving were assessed side-by-side in their effects on technology knowledge and adoption intention. This study shows that test-driving treatment largely (by 11%) and significantly increased BEV purchase intentions for a large group. Therefore, policymakers should facilitate direct experience to promote shifting individual motorised transport to electric vehicles in light of energy independence and climate considerations.
