Officers were paying special attention to sites where accidents due to excessive speed occur most often, Marcin Sulik from the Warsaw Police Department told reporters.
Police have urged motorists to slow down when approaching pedestrian crossings, bicycle paths and intersections.
Unmarked vehicles from a police unit called SPEED were also hunting for rule breakers, state news agency PAP reported.
Police have said the main cause of fatal road accidents caused by drivers in Poland is motorists failing to adapt their speed to traffic conditions.
A total of 1,896 people were killed and 24,743 injured in 21,322 accidents on Polish roads last year, according to police data.
At the start of 2022, stricter traffic rules took effect in the country with tougher fines for drivers as part of efforts to improve road safety.
Under rules that took effect in the country in May 2021, drivers have to give priority to people about to step out onto a pedestrian crossing, as well as those already on it.
