Hi As a coach-built motorhome, my unit is registered as zero emissions. This is because the original base vehicle manufacturer cannot just guess the final weight of the finished vehicle, so a special case has been made for coach-builts. Does this mean it will not be charged for entering the low emissions zone, or have they got this loophole covered? (I am an eternal optimist) I read somewhere recently about someone who picked up a family member from Heathrow in their motorhome and fell foul of the charge and got a £500 penalty. I used the Datrford crossings recently to and from Canterbury and saw the signs. As a Northener and infrequent visitor to London and surrounding areas, I am ignorant of the detail. Any advice appreciated.
