Since 2010, sections of the road have been transferred to the concession of the company "Avtodor", and travel on them became paid. It is critical for drivers, especially those who regularly use the highway, to be able to calculate the cost of travel correctlyto avoid unexpected expenses or fines for non-payment.

Even experienced drivers sometimes overpay or receive fines due to ignorance of the nuances. Here most common mistakes:

— Solution: Specify the category in PTS or on the operator's website.
❌ They pay for the wrong area:
— On M4 several operators, and if you pay the fare through wrong service, the money may not arrive.
— Solution: Use official sites (avtodor-tr.ru, platon.ru).
❌ Ignore discounts:
- Many people don’t know that cheaper at night, and the transponder gives additional discount.
— Solution: Plan your trips taking into account time of day and issue a transponder.
❌ They don't save receipts:
— If the payment “hangs”, without a receipt it will be impossible to prove it.
— Solution: Do screenshots payment confirmations.
❌ They drive without registration in Plato (for trucks >12 t):
- This is 100% fine 10,000 ₽.
