Police in Tehran issued a stern warning to road users amid an increase in the number of people covering up the license plates of mopeds with face masks, plastic covers, and badges. It is a criminal offense to cover a registration that can carry a penalty of six months to a year in prison, according to a senior police officer in Tehran on May 27, state news agency IRNA reported. Locals in Tehran say people are covering up their license plates for several reasons. As ever, road users are keen to avoid fines for infractions. In addition, many women who ride small mopeds are no longer wearing head scarves, as in the past, in a continued protest at the requirement. To avoid fines now that compliance is being monitored through CCTV, many cover their license plates.
