Good point... where it applies. It looks like eastern U.S. toll road systems count axles as an indication of vehicle size, so the extra axle carries substantial cost.
The only toll road that I know of in Canada is 407
(around Toronto) and its rate does not depend on the number of trailer axles (or even the length). The toll bridges which I have crossed in Canada (in the Vancouver area) and BC coastal ferries depend on overall vehicle combination length, regardless of the number of axles. Even though the Confederation Bridge
charges by axle, a tug with tandem-axle trailer would only be C$7.50 more than the C$53.00 cost of a tug with single-axle trailer. None of those are a cost problem for a tandem-axle trailer.
