A gross-weight restriction sign has a lower plate stating 'Except empty vehicles'. How should the plate be read?
Every vehicle may pass if its trailer is empty.
Loaded vehicles may exceed the limit by the weight of their cargo.
The restriction applies only while the road itself is empty.
An empty vehicle is exempt from the displayed gross-weight restriction.✓الإجابة الصحيحة
الشرح
The lower plate exempts vehicles that are empty from the displayed gross-weight prohibition. It does not raise the weight limit for loaded vehicles or exempt every vehicle returning from a delivery.
