Difficulty: MediumRoad Markings

On a two-way road, the broken white centre line changes so that the painted marks are noticeably longer than the gaps between them. What does this change in road marking indicate to the driver?

  1. A
    The legal speed limit on the carriageway is about to increase
  2. B
    Vehicles are entering a multi-lane one-way street system
  3. There is a hazard ahead, such as a bend or upcoming junctionAnswer
  4. D
    Parking along the edge of the carriageway is permitted at any time

Answer

The road marking indicates that there is a hazard ahead, such as a bend or junction.
Under Rule 127 of the UK Highway Code, a hazard warning line consists of painted white lines that are longer than the gaps between them. This marking warns drivers of hazards ahead, such as upcoming bends, hidden dips, or junctions, indicating that drivers should not cross or straddle the line unless they can see that the road ahead is clear.

Step-by-Step Solution

1
Identify the visual characteristics of the described road marking
The marking consists of broken white lines where the painted lines are significantly longer than the gaps between them.
According to the UK Highway Code (Rule 127), this specific ratio defines a hazard warning line, distinct from standard broken centre lines where gaps are longer than the painted lines.
2
Interpret the regulatory warning conveyed by the hazard line
The line alerts drivers to an upcoming hazard on the carriageway, requiring extra vigilance and caution.
Hazard warning lines are placed ahead of potential dangers such as sharp bends, crests, junctions, or reductions in road width.
