Traffic Control, Inspection and Remedial Action
Monitor control method, portable signals, changing traffic conditions, inspection records and safe removal.
How to prepare for supervisor assessment
Build the technical knowledge needed to judge work, then rehearse the supervisor evidence loop: review, observe, compare, intervene, record and verify.
Core concepts
Concept 1
Stop/Go, give-and-take, priority and portable signals each have site and authority limits.
Exam cue: Confirm approval and operating method before use.
Concept 2
Signal position, visibility, timings, intervisibility and pedestrian interfaces must match conditions.
Exam cue: Observe queues and behaviour rather than relying only on settings.
Concept 3
The site is reinspected after change, impact, darkness, weather or work progression and removed safely in sequence.
Exam cue: Record defect, action, owner and verification.
