The Association for Driving Licence Verification is calling on vocational fleets to check their drivers licences on a quarterly basis.
The body suggests fleets should undertake quarterly checks as a norm and more frequent checks where driver risk profiles warrant it.
Currently, most organisations, including those with vocational fleets, work on an annual or bi-annual basis.
The ADLV believes that fleets would be able to more quickly identify high-risk groups, such as those with mobile phone misuse and other offences, if checks were made more frequently.
Commercial checks can be repeated without the need for renewed consent each time as informed consent is given for a three-year period.
ADLV deputy chair Richard Payne-Gill said: "Previously annual or bi-annual checks were deemed to be sufficient. However, the latest checking systems, available through ADLV members, deliver more regular checks and are already being followed by some major fleets. In our view more frequent automated commercial checking varied according to driver risk profile, will establish it self as the best-practice for all professional fleet managers."
