Judging by some of the interviews on the TV news this week, quite a few drivers and operators were unaware of the arrival of the HGV Road User Levy so it might be worth reminding the more forgetful that other changes came into effect on 1 April.
Most notably, the operatives stopping your vehicles for roadside checks no longer work for the Vehicle and Operator Services Agency (VOSA) as that organisation has been subsumed into the newly-created Driver and Vehicle Standards Agency (DVSA).
The new body also includes the Driving Standards Agency (DSA) and it is now responsible for setting, testing and enforcing driver and vehicle standards in Great Britain.
This is a good thing, according to Roads Minister Stephen Hammond.
He said: "The creation of DVSA builds on the vital work that has already been done to improve road safety and offer modern, cost-effective services for motorists. The merged agency offers the opportunity to increase efficiency and further explore ways of providing innovative, convenient services."
The head of the new DVSA, Alastair Peoples, was similarly upbeat.
"By bringing testing and standards services into a single agency," he said, "we will make life easier for customers by putting them at the heart of the services they rely on and providing a more coherent approach to service delivery."
