Blood on the streets

^^ Interesting thoughts.

^ No, let's prolong it a little :)

As well as pay-per-load, you've got contractors driving their own vehicles and sometimes, such as for the construction of The Shard, a continuous concrete pour takes place requiring multiple trucks to travel at speed for prolonged periods (24 continuous hours in the Shard's case!) to and from the site. A delay could jeopardise the whole operation and cost a vast amount of money.

So, let's say they can apply for waivers for time-critical work, which would then allow TFL to put up signs alerting cyclists to the fact there will be HGVs along a route for a specific period of time and to avoid the area if possible and to be very wary of the heavy traffic if they can't.
