Difficulty: EasyMotorway Signs and Signals

Reflective road studs are placed along motorways to guide drivers at night and during poor visibility. Match each reflective stud colour with its correct carriageway location.

  • Red studsBetween the edge of the carriageway and the hard shoulder
  • Amber studsAlong the right-hand edge adjacent to the central reservation
  • White studsBetween separate traffic lanes on the main carriageway
  • Green studsAcross the entrance or exit slip road boundaries

Answer

Red studs match the hard shoulder boundary, amber studs match the central reservation boundary, white studs match the lane lines, and green studs match slip road boundaries.
According to Highway Code Rule 132, red reflective studs mark the left-hand edge of the carriageway next to the hard shoulder, amber studs mark the right-hand edge beside the central reservation, white studs divide individual traffic lanes, and green studs mark boundaries at slip road junctions.

Step-by-Step Solution

1
Identify the standard UK Highway Code colour codings for motorway road studs
Recognise the four standard colours: red (left edge), amber (right edge), white (lane dividers), and green (slip roads/lay-bys)
Highway Code Rule 132 sets mandatory colour designations for motorway orientation in the dark
2
Pair each stud colour to its exact road location
Red pairs with the hard shoulder boundary, amber pairs with the central reservation, white pairs with lane dividers, and green pairs with slip roads
Ensures accurate lane positioning and boundary awareness during nighttime or low-visibility driving
