Question

Difficulty: MediumMotorway Signals and Reflective Studs

According to the Highway Code, reflective road studs of different colours are used on motorways to help drivers navigate in the dark or poor visibility. Match each reflective stud colour to its correct boundary or layout location.

  • Red studsBetween the left edge of the carriageway and the hard shoulder
  • Amber studsAlong the edge of the central reservation on the right
  • Green studsAcross slip road entry and exit boundaries
  • Fluorescent green/yellow studsAt temporary roadworks and altered lane layouts

Answer

Red studs match with the boundary between the left edge of the carriageway and the hard shoulder; Amber studs match with the edge of the central reservation on the right; Green studs match with slip road entry and exit boundaries; Fluorescent green/yellow studs match with temporary roadworks and altered lane layouts.
Under Highway Code Rule 132, red studs mark the left edge of the carriageway (hard shoulder), amber studs mark the right edge (central reservation), green studs mark slip road entry/exit points, and fluorescent green/yellow studs mark temporary changes or roadworks.

Step-by-Step Solution

1
Identify the outer boundary colours of the motorway carriageway
Red studs are positioned on the far-left boundary next to the hard shoulder, while amber studs are positioned on the far-right boundary next to the central reservation.
Highway Code Rule 132 defines standard outer edge markings for driver orientation in poor visibility.
2
Identify junction and temporary hazard markings
Green studs indicate slip roads where traffic merges or diverges, and fluorescent green/yellow studs denote temporary roadworks or altered traffic flows.
Distinctive colours alert drivers to potential conflicting traffic paths or altered layouts ahead.
