National permit vs authorisation: the annual date most fleets miss
A national permit truck has two dates to track: the permit itself and the authorisation that lets it run across India. Why they differ, how the authorisation is paid, and how to stop it lapsing.

Ask a long-haul fleet owner when his trucks' national permits expire and he will usually know. Ask when the authorisations expire and the answer is often a pause. The two are different documents with different dates, and the authorisation is the one that lapses without anyone noticing.
Two documents, one truck
A goods vehicle needs a permit to carry goods for hire. Section 66 of the Motor Vehicles Act makes a permit necessary, and Section 88 governs when a permit issued in one state is valid in others. The national permit scheme, which sits under Section 88, lets a goods vehicle run across the country on one permit instead of a stack of counter-signatures.
It works in two parts:
- The national permit is issued by the transport authority of the truck's home state. It has its own validity and is renewed with that authority.
- The national permit authorisation is what makes the permit valid outside the home state. It carries an annual fee, paid online through the Parivahan national permit service, and it has to be renewed every year.
Because the authorisation is annual and paid online, it does not come with a visit to the RTO that would remind anyone. It is a payment on a website on a date that is different from every other date on the truck.
What happens when the authorisation lapses
A truck whose authorisation has lapsed can still hold a valid home-state permit. Inside the home state, it may be fine. The moment it crosses a state border, it is running outside its permit conditions. That is a permit violation under Section 192A: up to ₹10,000. States can set different compounding amounts.
The fine is rarely the worst of it. A truck stopped on a highway two states from home, with a load on board and an authorisation that ran out last week, can be held until the problem is sorted. Paying the authorisation online is quick; getting the truck released and the load delivered on time is not.
Why fleets miss it
- It looks like the permit. Registers often have one column for "permit" and the munshi writes the permit's date in it.
- The dates drift apart. The permit and the authorisation may have started on the same day, but renewals rarely happen on the same day, so after a year or two they sit in different months.
- It is paid online. Nobody goes to the RTO, so nobody at the RTO mentions it.
- Trucks change hands. When a truck is bought second-hand, the authorisation's date is often not recorded at all.
How to keep both dates straight
- Give the permit and the authorisation separate columns, or separate rows in your calendar. Never one date for both.
- Read both dates from the vehicle's record, not from memory or a receipt in a file. The permit details are on the VAHAN record for the truck.
- Set reminders at 30, 15, 7 and 1 days before each date. Assign the authorisation reminder to the person who makes online payments, which may not be the person who visits the RTO.
- After paying, download the authorisation and put it with the truck's papers and in the driver's phone. Checkpoints ask for it.
The national permit guide and the national permit authorisation guide cover validity, renewal and the documents needed for each.
State permits are not simpler
Fleets that run on home-state goods carriage permits have the opposite problem. Every other state the truck enters needs a counter-signature or a temporary permit, each with its own date. If your trucks regularly leave the home state, the national permit with its single annual authorisation is usually less work to track, as long as somebody tracks it. Each state's position is on our state rules pages.
Road tax is a third, separate date
Neither the permit nor the authorisation replaces road tax in the home state. A national permit truck still pays its home state's road tax on that state's schedule. We explain how the two interact in Road tax for national permit trucks.
Where PRACHSO fits
PRACHSO keeps the national permit and the authorisation as two separate dates on every truck, read from the vehicle record. Each gets its own reminders on WhatsApp, sent to the person whose job it is: the permit to the munshi who deals with the transport authority, the authorisation to whoever pays online. When the payment is done, the new authorisation goes into the document vault and the driver's Roadside Pack. PRACHSO does not issue permits or pay fees: it hands off to the official portal or to your own agent.
In PRACHSO
The reminder goes to the person who acts
Owner, munshi or driver, on WhatsApp, in their own language, 30, 15, 7 and 1 days before the date. Nobody types a date; PRACHSO reads them from VAHAN and SARATHI.
