Utrecht voert in de nacht van 9 op 10 juli 2026 op 241 straten tegelijk een maximumsnelheid van 30 kilometer per uur in. Afgeplakte verkeersborden worden op voorhand geplaatst waarna medewerkers in één nacht de stickers zullen verwijderen. De gemeente verlaagt de snelheid omdat dit veiliger is voor weggebruikers.
Wales implemented a pretty widespread version of this, changing roughly a third of all of their roads from 30 mph to 20 mph (pretty close to 50 and 30 kph respectively). Test areas before the full implementation seemed to go well, and the first year of the reduced limit saw casualties on affected roads drop by a quarter compared to the prior year. That’s only one year of data, and casualties were already trending down anyway, but it does seem promising
It has been very controversial, though. A lot of people do not like it and are fighting to repeal it
