The Garda National Roads Policing Bureau (GNRPB) (Irish: Biúró Náisiúnta an Gharda Síochána um Póilíniú Bóithre)^[1] is the roads policing unit of the Garda Síochána. Prior to 2018, it was known as the Garda Traffic Corps (Irish: Cór Tráchta an Gharda Síochána).^[2][3][4]

The main responsibility of the Garda National Roads Policing Bureau (GNRPB) is to improve road safety and reduce the incidence of fatal and serious injury on Ireland's roads.^[5]

Each Division of the Garda Síochána now has a Roads Policing Unit of its own,^[6] with an additional regional unit assigned to the Dublin Metropolitan Region.

Following a review by the Traffic Corps of collisions involving fatalities, serious injury, and minor injury, the organisation compiled a list of 'Collision Prone Zones' which was published on the Garda website.^[9][10] These zones were subsequently subject to 'targeted enforcement of road traffic and road transport legislation'.^[11][12] As of 2016, these zones are subject to monitoring by the operators of speed detection vans.^[9]

Garda Roads Policing Units use a range of vehicles, including motorcycles, marked and unmarked cars and 4x4 vehicles. Marked Roads Policing Unit vehicles are visibly different from standard Garda vehicles in that they feature the words "Roads Policing" and its Irish translation, "Póilínú Bóithre", along with full-coverage high visibility blue and yellow Battenburg markings.^[13]

Automatic number-plate recognition (ANPR) was introduced for use by the Traffic Corps in 2009, and the 'nationwide roll-out of ANPR technology [..] completed in 2010.^[17] While ANPR systems are standard on cars assigned to Roads Policing units,^[18] as of March 2017^[update], the expansion of the use of ANPR technology was due to continue through to June 2019,^[19]

Traffic Blues is a documentary series broadcast on RTÉ One. It follows various traffic officers from the Garda Síochána.^[20]
