A minicab, short for "miniature taxi" or "private hire vehicle," is a type of passenger vehicle for hire with a driver, but unlike traditional taxis, minicabs must be pre-booked through a licensed private hire operator. These vehicles are not allowed to pick up passengers on the street without a prior booking. Minicabs are a common mode of transportation in many cities and are often used for private, pre-arranged journeys.

In contrast to taxis, which can be flagged down on the street, minicabs operate on a pre-arranged basis, typically through a phone call or a dedicated mobile app. Passengers must book the minicab in advance, specifying the pickup location, destination, and desired time.

It's important to note that regulations for minicabs and private hire vehicles vary from one location to another, and licensing authorities typically impose specific requirements to ensure passenger safety and proper service standards.
