On UK smart motorways, does a temporary speed limit continue if subsequent gantry signs are blank?
I’ve noticed this recently on some motorways. You’ll pass a gantry showing a temporary speed limit, like 50 or 60, but abruptly the gantries go completely blank.
There’s no national speed limit sign, no “end” sign, and no new speed limit shown just nothing.
It feels like deliberate & unnecessary ambiguousness especially if you’re driving on a road with many cameras.
I often have people driving up my arse in this situation so wondering have I missed something, does a blank sign indicate a fault or do they really think this is the best way to regulate traffic?
