The agency can only check details from the information provided to them by Cemex.
Call me a cynic, but the agency has no way of checking that the licence it has checked belongs to the actual driver of the vehicle concerned.
The only way to do that is to actually check photo ID licences, on the ground.
From my experience, copies of drivers details and licences should be kept at each operating centre. If Cemex wish to involve outside agencies to back this up so well and good.
