San Francisco Airport
An 'or else' restriction.
The SFO terminals need a lot of delivery truck service, but you have to be careful. A large truck can literally get stuck in the narrow confines of the passenger area.
The huge airline cargo areas are separate, and mostly reached via North Access Road, or North (also South) McDonnell Road. Pay close attention, since most roads maps aren't very clear on this.
There are dozens of air frieght companies in South San Francisco and the nearby towns, but none on the airport grounds proper.
Approaching SFO along 101 northbound.
The terminals have special areas where trucks can drop their loads, on the lowest or 'ground' access level.
The SFO police enforce this restriction for security reasons, and besides, when a
careless trucker gets stuck at the terminal area, it makes the nightly news. Embarrassing!
