In London, England I don’t drive a Private Car I drive a 3.5 Ton Van. Now all the restrictions on Waze are good. But when it comes to Vehicle type I am not a Truck since I can get through a 6FT 6" width Restriction. 
I am in the Best terms a “Commercial Vehicle” or you could call it a “Van” for short.
In London the Royal Parks are off limits to me and all other “Commercial Vehicle’s” e.g Motorbike couriers and any car or van that advertise a company on them. Waze directs me through the Royal Parks since they are normally Traffic Free but this is due to the Parks only allowing Private Cars and Taxis through them.
