Grab
The dominant ride-hailing app, functionally identical to Uber — fixed upfront pricing, cashless payment, and wide availability outside of surge periods.
Street taxis
Metered and plentiful, though not everywhere allows a street flag-down — some areas require a taxi stand. Surcharges apply for late-night trips, advance booking, and pickups from the airport or Marina Bay Sands.
Car rental
Rarely worth it for visitors — the MRT covers most tourist needs, parking is expensive and limited, and Singapore's Electronic Road Pricing system adds complexity most short-term visitors don't need to deal with.
