Report defective or dangerous road markings

Yellow lines

Yellow lines are provided where there is a need to restrict parking to help ease traffic flow and prevent obstructions on the highway.   

There are two main types used: 

  • Double lines usually mark lengths of road where there is no waiting at any time. There are exceptions to this, and extra plates fixed to lighting columns or posts will tell you what the restrictions are. 

  • Single lines usually indicate a shorter period of restriction. Additional plates will show the actual times. 

Loading restrictions are shown by yellow markings on the kerb and on any added plates.   

The Highway Code gives examples of the lines in normal use and their associated rules.   

All lines on the highway must be authorised by the county council. Special lines are allowed with approval from the Department for Transport, or if they are experimental and under trial. 

White lines

White lines on the road are provided to help road users by giving different types of information on lane use and directions. 

Lines on the road

Road markings are as important as signs. Horizontal markings inform and warn road users of approaching situations that will require them to take action (i.e. solid white line - do not cross, or lane line - turn right).    Diagonal lines also give instruction (i.e. stop or give way).
