From July 1, private-hire cars must display a pair of decals (like the one pictured above) on the front and back windscreens of their vehicles.

Each decal measures 14cm by 10cm.

The decal is tamper-evident, which means enforcement officers will be able to tell if it has been removed and re-pasted.

The Land Transport Authority said previously the measure is "to allow for easier identification of registered private-hire cars, and facilitate enforcement against offences such as unregistered cars providing chauffeured services, or private hire cars picking up passengers by street-hail".

Failure to affix these decals will be an offence under the Road Traffic Act.

Owners of private-hire cars registered with the LTA on or before Feb. 28, 2017, will have had their first pair of tamper-evident decals affixed at no cost.

Owners who registered their vehicles after Feb. 28 will have to get the decals affixed at S$20 (including GST).

They can only obtain and get their decals affixed at the following locations:

- Vicom/JIC inspection centres

- STA inspection centres

- Uber and Grab affixing centres

Tamper-evident

The tamper-evident decals will be inspected when private-hire cars undergo vehicle inspections.

The vehicle owner will not be allowed to renew road tax for the vehicle if the decal has been tampered with.

However, according to a Straits Times report, only 900 out of an estimated 20,000 to 30,000 private-hire cars here have had mandatory stickers pasted on them.

There is also the expectation that a significant number of private-hire car drivers will stop plying the roads when their vehicles are made easily identifiable. This is so as part-time drivers might be considered moonlighting, which is not allowed while holding down certain full-time jobs, or it might just be unglamorous to have such decals put up.

ST also said 24,000 people have applied for the Private Hire Car Driver's Vocational Licence (PDVL), which all current private-hire drivers must apply for by the end of next month.

The LTA said of the 24,000 people who have applied, 6,000 have completed the relevant checks, and it has given approval for them to register for the PDVL course.

Only 400 of those who passed screenings have registered for the course.

Applicants whose applications reach LTA before June 30, 2017, have up to one year to attend and pass the PDVL course.
