Road markings convey information, issue orders, or provide warnings. As a rule of thumb, the significance of the message increases with the amount of paint used.
There are three main types of road markings:
Along the middle of the road:
- Short broken white lines separate lanes.
- Longer broken white lines serve as hazard warning lines; overtaking is only permitted if the road ahead is clear.
- Double white lines with a solid white line on your side indicate that you must not cross or straddle the line.
- White diagonal stripes or chevrons separate lanes of traffic or protect traffic turning right.
Along the side of the road:
- A white line denotes the edge of the carriageway.
- Yellow lines indicate waiting and stopping restrictions.
- Zigzag lines (white at pedestrian crossings, yellow outside schools) signify no stopping or parking at any time.
Lines on or across the road:
- Broken lines across the road indicate ‘give way’.
- A solid line means ‘stop’.
- Various markings on the road (e.g., ‘give way’ triangles, road-hump markings, arrows) warn of hazards.
To gain a comprehensive understanding of road markings, it’s advisable to consult resources such as Know Your Traffic Signs and The Highway Code.
Reflective studs are commonly found on motorways and other roads, particularly beneficial during nighttime and low visibility conditions.
