3.1 Street-Hail vs Booking: Taxis and Private Hire Cars

Two Channels for Getting a Ride

Singapore's point-to-point (P2P) transport framework recognises exactly two channels through which a commuter can engage a ride: street-hail and booking. Understanding which vehicles can use which channel — and why — is one of the most heavily tested ideas in the TDVL theory papers, because it sits at the intersection of vehicle type, driver licence, and passenger expectation.

Street-hail means a commuter flags down a vehicle directly, either by waving at it while it is moving along a public road, or by waiting at a designated taxi stand or taxi stop for the next available vehicle to pull up. Booking means the commuter arranges the ride in advance, either by telephone (for example, calling an operator's dispatch hotline such as CDG Taxi's 6552 1111) or through a mobile ride-hailing app that matches the commuter with an available driver.

Only Taxis Can Be Street-Hailed

The rule that anchors this entire section is simple to state but easy to misapply under exam pressure: taxis may be street-hailed — along most public roads outside restricted zones, or at a taxi stand or taxi stop — while private hire cars (PHCs) can never be street-hailed under any circumstance. A PHC can only be engaged through a booking made with a licensed ride-hailing operator's app or phone line.

This creates a scenario that appears often in TDVL assessment papers: a driver who holds a valid TDVL is currently driving a private hire car, and a pedestrian on the roadside waves to try to flag the car down. Even though the driver's vocational licence would allow them to accept a street-hail if they were driving a taxi, the vehicle in front of them right now is a PHC — and a PHC cannot legally accept a street-hail. The determining factor is the vehicle type, not the driver's personal licence. The correct professional response is to decline politely and direct the would-be passenger to book a ride through the app.

TDVL vs PDVL: Two Different Scopes of Authority

Singapore's vocational licensing system distinguishes between two licences that look similar on paper but grant different scopes of authority:

• TDVL (Taxi Driver's Vocational Licence): holders may provide chauffeured services using either a taxi or a private hire car. This is the broader of the two licences.
• PDVL (Private Hire Car Driver's Vocational Licence): holders are licensed for private hire cars only. A PDVL does not authorise driving a taxi commercially.

Because the TDVL is the broader authority, it is common for a TDVL holder to spend part of a shift driving a taxi (where street-hail applies) and part of a shift driving a chauffeured PHC (where only bookings apply). Exam questions frequently test whether a candidate can correctly identify which rules apply given the vehicle currently in front of them, not just the licence in their wallet.

Booking Channels and Fare Models

Whether a booking is made by phone or through an app, the licensed operator handling the booking may offer the ride at one of two fare models: a metered fare, calculated by the taxi's meter based on distance and time, or a flat fare, a fixed amount set by the operator for that specific trip. When an operator offers a flat fare for a taxi or PHC booking, that fare must be shown clearly within the app to the commuter before the trip begins, so the passenger knows exactly what they will be charged. (Chapter 4 covers the mechanics of metered and flat fares, surcharges, and receipts in depth — the point to master here is simply that both fare models are legitimate options for a booking, and that a disclosed flat fare is binding for that trip.)

A Simple Decision Framework

When approached by a potential passenger, a TDVL holder can resolve almost any street-hail-versus-booking question by asking two things in order:

1. Did the passenger arrive through a street-hail (waving on the road, waiting at a stand or stop) or through a booking (phone/app)?
2. If it was a street-hail, is the vehicle currently a taxi? If yes, and the location is a permitted stopping point, the pickup may proceed. If the vehicle is a PHC, the street-hail must be declined regardless of location, and the passenger should be directed to book through an app.

Mastering this two-step check resolves the majority of "which rule applies" questions that combine vehicle type, licence type, and channel of engagement into a single scenario.

Common Exam Traps in This Section

Two mistakes recur most often on the assessment. The first is assuming that because a driver holds a TDVL, any street engagement is automatically legal — the exam wants the candidate to check the vehicle, not the licence, before accepting a street-hail. The second is assuming a flat fare shown after a booking is confirmed can still be adjusted upward for heavier traffic or a longer route; once an operator has disclosed a flat fare to the commuter upfront, that fare is fixed for the trip, and the driver has no discretion to add to it after the fact. Keeping the vehicle-first check and the fare-is-fixed-once-disclosed rule front of mind resolves most street-hail-versus-booking scenario questions correctly, even when a question layers in extra detail about the passenger, the location, or the time of day to make the underlying rule harder to spot.
