This is wat I was looking for...
I have to say: the one-way-roads are fun and is should be very logical to let trucks or busses to load at both sides of the road at a 1way road. Or am I mistaken?
By the way, it is already happening... When a truck breaks down in or just in front of the DTRS, a overtaking truck will stop at the other side of the road and, believe it or not, it unloads (or loads) it's cargo. Mind that both trucks drove in the same direction from a 1way road
Owh, and why can't you mark 1 way roads with a sign-like 'sign' instead with the green arrows on the road. It should be nice to use a sign at the start of a 1 way roadblock and one at the end. (Something with trains?

)
But about the loading and unloading at both sides of the road in a DTRS: Is it implemented or just coincidence/bug when a vehicle breaks down?
Greetings.
