Males Forbidden to Ride Motos as Passengers

Ecuador's National Traffic Agency has issued
a national directive outlawing ridership on 'motos'
as passengers on public roads and highways.

The move follows an increase in crime by men riding motos as
'pasajeros'.  Almost half of reported crimes in recent times
in La República have involved motos.

Murders by moto passengers have become an increasing problem,
especially in some crime-ridden coastal areas where
drug traffickers have become a primary police target.

Exceptions to the new rule are being made under certain conditions
for moto-riding families.

Correction.... the opening post of this thread did not mention that the new regulation applies only to a restriction on male passengers.
This prohibition of passengers on motorcycles has been done in various cities in Colombia, for some time now, off and on, in an effort to combat crime.  The mobility of a motorcycle makes street crimes easy to commit, and easy to escape the scene - but two people are needed, one to drive, one to rob.  In Colombia another word for the passenger is parrillero, for riding pillion.

The prohibition in Colombia generally applies to any passenger, male or female.

It's pretty clear this does not reduce the crime situation - only the law-abiding obey the prohibition, and it's a big inconvenience for them.  The criminals, who are planning to rob someone at gunpoint, apparently do not hesitate to break the no-passenger law, too...and they can generally get away from the police if chased.
