Can anything be done about Poliscan falses?

[Abarth695]

So the Poliscans attached to the toll overpasses in Queensland, Australia, if I'm correct, the alert comes on immediately as I go through the overhead structure, no warning at all. Am I right to assume that a real Poliscan would give me virtually no warning at all as well?
Or is it the same that it would jam at that instant and I would have the time to slow?
Hope that makes sense

It's likely jamming would be ineffective to the overhead gantry mounting at close range...your Sensors are not oriented correctly to neutralize for that angle of incoming IR.
