Select all that apply: which statements correctly distinguish speed advice or camera information from regulatory speed limits?
A speed shown with a bend warning can be advisory rather than a statutory limit.✓پاسخ درست
A blue minimum-speed roundel is only a recommendation.
A camera-enforcement sign does not by itself introduce a new numerical limit.✓پاسخ درست
A red-ringed maximum-speed sign may be ignored when the road is clear.
توضیح
An advised speed beneath a hazard sign helps a driver choose an approach speed but lacks the red-ringed control that creates a maximum limit. A camera symbol reports enforcement equipment rather than setting a number; the blue minimum roundel and red-ringed maximum are mandatory instead.
