Inspector General of Police Joseph Boinnet on Friday introduced daytime alcoblow inspections to nab drivers who drink and drive during the day.
The police boss stated that the move was aimed at reducing the number of deaths witnessed on the road during the December festive season.
The breathalysers, commonly referred to as alcoblow, were declared illegal by the Court of Appeal in 2017.
A three-judge bench ruled that the use of the gadget to arrest drivers was against the Constitution.
The ruling was made after a successful petition by Richard Ogendo, a Nairobi businessman, in 2014 over the abolishment of the gadget.

Through the petition, Ogendo argued that the rules that took effect in 2011, were not consistent with the constitution.
The businessman further pointed out that the dragging of the drivers out of the vehicles when being arrested and made public through the media was uncalled for.
National Transport and Safety Authority (NTSA), however, disregarded the court order and continued with the crackdown.
The procedure had been temporarily suspended and re-introduced in 2013 by the then Transport CS Michael Kamau.
Kamau stated that drivers caught would pay a fine of Sh 100,000, two years in jail or both.
In addition, their vehicles would be detained at the police station as part of the directive.
