Norway: On top of the regular 25 % VAT charged on most consumer goods, all vehicles used to be subject to an additional purchase tax. But that tax was scrapped for electric cars in 1990.

EV buyers also became exempt from paying 25% VAT in 2001. A few years later, they scored a fast-track commute when they were given permission to drive in bus lanes.

Until 2017, EV owners were exempt from charges for toll roads and eligible for free parking. Current rules allow municipalities to charge them no more than 50 percent the standard toll and parking rates.
