Priority Bus Route

The Priority Bus Route (PBR) also known simply as the "bus route" is an East to West thoroughfare that has restricted access for the Public Transport Service Corporation (the national bus service) buses, state and emergency vehicles, as well as limited private citizens and a finite number of red-banded maxi taxis, the drivers of which are allowed to purchase a pass annually. The PBR was built in stages first running from Tunapuna to Port of Spain, then later extended further east up to Arima.

For a brief period, the PBR was opened to all motorists during certain off-peak hours as long as car pooling was exercised. In 2014, for the two days of Carnival, the PBR was also open to all motorists.
