Yellow lines

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

There are only two types used:

• Double lines to mark lengths of road where there is no waiting at any time.
• Single lines indicate a shorter period of restriction such as daytime. Supplementary plates will show the actual times.

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

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