Crossing the border from Latvia is completely hassle-free now that the Baltics belong to Schengen. Getting over the border from Russia will take quite a bit longer. In both cases, be sure to bring your car’s registration papers and a valid insurance policy, such as the international green card. You can also buy insurance right at the border station. Please note that the speed limit on highways is 90km/h, in the cities 50km/h, unless otherwise noted, and the headlights have to be always turned on. For fares and regulations on bringing a car by ship from Finland or Sweden, contact the ferry companies.
