Finland fines speeders a share of their income, so a Nokia director paid 116,000 euros
the problem
A flat speeding fine barely registers for a rich driver but can be crushing for a poor one, so it deters unevenly
background
A fixed-currency traffic fine — say, 200 euros for a given speeding offense — imposes wildly different real burdens depending on who pays it: trivial pocket change for a wealthy driver, a genuine hardship for someone living paycheck to paycheck. That mismatch undermines the fine's entire purpose as a deterrent, since deterrence depends on the penalty actually being felt, and a flat fee is only ever calibrated correctly for one income level at a time.
Raising the flat fine to make it sting for wealthy drivers would have made it ruinous for poor ones, and means-testing every fine case by case would have required a judge or clerk to evaluate each offender's finances individually — expensive and slow for an offense as routine as speeding. Finland, beginning general criminal penalty reforms in 1921, took a different approach for exactly this reason.
what everyone would do
The available levers were a single higher flat fine, which would have been either too lenient for the wealthy or too harsh for the poor, or individualized judicial review of every speeding offender's finances, which does not scale to an offense issued by the thousands every week.
what they saw
A fine only deters if it hurts, and a fixed number does not hurt the same amount twice; Finland stopped fining a currency amount and started fining a fraction of a day of the offender's own income.
the move
Finland's day-fine system denominates penalties not in a fixed currency amount but in 'day-fines' — units equal to roughly half the offender's daily disposable income, multiplied by a number of day-fines set by how serious the offense was. The system uses the government's existing tax records to calculate the daily income figure automatically, so no separate financial investigation is needed.
why it works
By tying the penalty to something that automatically scales with the offender — their own documented income — the system achieves the effect of an individualized assessment without the cost of one, because the tax records already exist and the formula does the work a caseworker otherwise would. This also makes the deterrent's severity self-correcting over time and across the population: as an offender's income rises or falls, so does their exposure, keeping the sting roughly constant without any new legislation. Critically, this only works because it is applied to something citizens already report accurately for other reasons (taxation), so the income figure isn't something the state has to newly investigate or that the offender can easily hide.
the payoff
In 2002 Nokia director Anssi Vanjoki was fined 116,000 euros for riding a motorcycle 75 km/h in a 50 zone.
where it breaks
It depends entirely on reliable, verifiable income data — informal or cash economies where income isn't documented make the formula unenforceable, and self-employed or highly variable-income individuals can be harder to price fairly than salaried employees. It also invites the criticism that punishing the same act with wildly different fines feels, to the wealthy offender, like the law is treating them differently for the same behavior, which can generate political backlash even when the underlying deterrence logic is sound.
what came after
Finland's day-fine model, refined through the 20th century and extended to traffic offenses, has since been adopted in some form by Sweden, Denmark, Germany, and several other European countries, and periodically resurfaces in US and UK policy debates over 'means-adjusted' fines whenever a case like Vanjoki's draws international attention to the wealth-blind flat fine as the default everywhere else.
