[Tagging] tagging no truck access in US

[SomeoneElse]

It might seem a silly question, but what's a truck?  You're correct that 
HGV in the UK has a specific legal meaning*, but does "truck" have one 
in the US?

If it doesn't, would something like a Ford F-series count?  What 
something like an El Camino?

Cheers,
Andy

* Westminster Council via Google reckons that:
The technical definition of an HGV is a 'mechanically propelled vehicle 
that is:

    * of a construction primarily suited for the carriage of goods or
      burden of any kind; and
    * designed or adapted to have a maximum weight exceeding 3,500
      kilograms when in normal use and travelling on a road laden.'
