While some border crossings may request the STS, it is not universally demanded. For drivers under 14 years of age, a foreign passport is generally required for exit from Russia. For drivers aged 14 and above, a Russian internal passport is sufficient for exiting Russia. When entering Belarus, the primary document checked is the passport. For minors traveling without parents, a notarized consent from one parent is required for exit from Russia. The 'blue card' (vehicle insurance) is mandatory for driving in Belarus and can be purchased at the border.
