# Requirement change

Finance signed off on a new tariff this morning and it is live from now on.

- **The first hour is free**, for every vehicle. Short-stay traffic is what we want at the mall.
- The second and third started hours are charged at the standard rate:
  motorbike **500**, car **1000**, truck **2000** per started hour.
- From the fourth started hour onward it is the long-stay rate:
  motorbike **1500**, car **3000**, truck **6000** per started hour.

Rounding does not change: a started hour is a whole hour. So 61 minutes is two started hours —
the first free, the second at the standard rate, and a car pays 1000.

Worked example, so we agree on the arithmetic: a car staying three hours and one minute has
started four hours. Free, then 1000, then 1000, then 3000. It pays 5000.

Charges are still per vehicle, still in minor units, and nothing about where vehicles park
changes.
