Road markings help road users travel in safety. The markings themselves are laid with coloured thermoplastic material for extra durability; this contains very small glass beads to help them show up in vehicle headlights.
Road markings may indicate lanes, tell drivers to `Give Way`, warn drivers of hazards ahead or of any restrictions nearby.
The most commonly used road markings are dashed white lines to warn drivers to `Give Way` to other road users and to indicate the centre of the road; they also tell drivers to `SLOW` down. Yellow lines are used to show where parking restrictions exist.
The Highway Code provides details of road markings in normal use.
All road markings placed on a highway or road to which the public have access must be either prescribed by Regulations or authorised by the Secretary of State for Transport. Road markings may be placed on a highway only by or with the consent of the Highway Authority.
Certain road markings may be used only if supported by a traffic regulation order or other statutory provision. Some markings have legal implications in that not complying with them could constitute a traffic offence under Section 36 of the Road Traffic Act 1988.
The Traffic Management Section for Leeds City Council, Highways Services are responsible for the implementation of Traffic Regulation Orders, and the delivery of local traffic schemes, such as traffic calming initiatives.
