Are heavy vehicles subject to the same tolls as cars?
No, rates are different according to the class of the vehicle. First of all because heavy vehicles consume more asphalt, and require higher maintenance costs. And in the event of an accident, they require even more demanding relief efforts.
There are 5 classes: A, cars; B, the vans; C, 3-axle heavy vehicles; D, 4-axle heavy vehicles; E, 5 or more axles vehicles.
