The controversial new fare structure that has caused protests and work stoppages by taxi drivers is due to come into force across the country today.
The new charging system is the same in all parts of the country and replaces the previous situation whereby fares were set by 35 different local authorities.
Hundreds of taxi drivers, mainly those based in Dublin, have a series of work stoppages to protest at the reforms, claiming they will lose thousands of euros every year as a result.
They are particularly angry at the abolition of luggage charges and the special €1.50 fee for pick-ups at Dublin Airport.
Taxi drivers have until October 16th to update their meters to take accounts of the changes.
