With passenger number caps now in place for public transportation and private vehicles, the police are carrying out patrols in at least 33 areas in the city. The patrol checkpoints include bus and train stations, toll roads and border areas such as Kalideres in West Jakarta, Kalimalang in East Jakarta and Ciputat in South Tangerang, Banten.

“We will stop vehicles and check whether or not they are adhering to physical distancing measures, which limit passenger numbers and [require that everyone] wear masks,” Jakarta Police spokesman Sr. Comr. Yusri Yunus told The Jakarta Post on Friday.

Public transportation services have been instructed to operate at 50 percent of their regular passenger load factor with hours of operation limited to between 6 a.m. and 6 p.m. Private vehicles must also limit the number of passengers in each vehicle.

“For example, a private car with a capacity of six people must only be filled with three people. Two people are allowed to ride private motorbikes as long as they live in the same house. All passengers must wear masks,” Yusri said.

Any vehicles that do not comply with the regulation will be “sanctioned” and required to turn around, with later entry permitted only if the number of passengers is reduced, he added.

The Jakarta Traffic Police’s Twitter account @TMCPoldaMetro posted a video showing the police stopping a bus to make sure it was carrying only 50 percent of its passenger load factor and that all passengers wear wearing face masks. Every two-seat section of the bus was occupied by only a single passenger, as required.

Yusri further said the police also gave out free masks to drivers and passengers who were not wearing masks on Friday.

The Jakarta administration issued Gubernatorial Decree No. 33/2020, which follows up on the technical details of Health Ministry Regulation No. 9/2020 on the guidelines for the PSBB. The regulation prohibits ojek (motorcycle taxi) from picking up passengers. Ojek drivers are only permitted to transport goods.

However, some drivers seemed to be unaware of the new regulations. At Palmerah Station in Central Jakarta on Friday, a police officer stopped an ojek driver for riding with a passenger. The officer instructed the passenger to immediately get off the motorbike, @TMCPoldaMetro reported.

“A Jakarta Traffic Police officer informed an app-based ojek driver about the implementation of the PSBB [and told him] not to pick up passengers around Palmerah Station,” @TMCPoldaMetro tweeted.

In addition to enforcing the restrictions on the streets, a joint team comprising Jakarta Police, Indonesian Military and Jakarta Public Order Agency personnel will also patrol supermarkets and minimarkets, which are allowed to operate during the partial lockdown period to supply daily needs.

“Our personnel will make sure supermarket and minimarket visitors maintain a safe distance from each other,” Yusri said.

Under the PSBB, which will last for at least two weeks until April 23, residents are required to stay at home as schools, offices and public spaces will remain closed during this period. Gatherings of more than five people in public spaces will be not allowed. These measures have been in place for the past few weeks in Jakarta, but violators will now face sanctions as Jakarta ramps up its fight against COVID-19.
