Why do you Show Different Tolls for 2-axle Trucks
On many US toll facilities, you have to pay different tolls if you drive a 2-axle pick-up with 4 tires, 2-axle pick with 6-tires, or if you drive a 2-axle commercial truck. Often the tolls are same but on some roads, they are not. You can pick appropriate vehicle class (personal pick-up truck or 2-axle truck) to get the correct toll.
