    What is the underage driver sign that 17-year-olds must use in Finland?

    A visible marker for the youngest drivers.

    Short answer

    The Finnish Government says that, to help enforce the night driving ban, a 17-year-old driver must mark their vehicle with an underage driver sign from 1 October 2026. Breaking this obligation can lead to a traffic penalty fee of €100 for the driver. Traficom says the sign is mandatory for all 17-year-olds driving passenger cars from that date and that it would give more information closer to the start.
