Near Breda the fixed round sign shows '100' and at the same time the matrix sign above it shows '80'. You are driving 90. What is true?
You are breaking the rule: the lower of the two, 80, applies
You are driving legally: the fixed sign (100) is the 'real' sign, the matrix sign is just advisory
Explanation
Wrong — trap: technology confused with non-binding status. A matrix sign is a full traffic sign and the lowest speed applies when both are shown (Book p.49-50).
