Off-hand I can only think of three toll routes in the UK, plus the
London Congestion Zone (which I think doesn't have a transponder).

I realise toll routes are much more common in the USA.

I didn't realize there were no transponders. It's enforced entirely
with photographs of license plates?

Even toll roads in the USA are enforced by photographs of licence plates

No one enforces toll collection with photographs of license plates as
the primary system of enforcement. It supplements transponders.

That depends on what you mean by "primary". CTRMA (Austin, TX) and NTTA
(Dallas/Ft Worth, TX) give discounts for using a transponder, but those
without are simply billed by mail at the cash rate. As long as the bill
is paid on time, there are no fines.

(I don't think cars without transponders are impaled on spikes).

Hah! I like spikes to protect grade crossings.

So an errant driver would be brought to a halt on top of the tracks,
directly in the path of an approaching train, rather than (as most do
today) make it across safely?
