Traffic Management

Traffic signs and tourist signing

Report a problem with any sort of road or traffic sign or marking

Traffic signs

New signs are installed by the Highway Authority to regulate, advise and give directional information to the road user.  The Highway Code gives examples of the most common signs in normal use. Signs include:

  • Regulatory Signs - signs with red circles
  • Warning Signs - mostly triangular
  • Direction Signs - mostly rectangular. Destinations and map type
  • Information Signs - mostly rectangular.

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

Tourist Signing (Brown signs)

White on brown tourist signs are part of the family of road traffic directional signs. Their main purpose is to guide visitors to a destination along the most appropriate route, particularly where destinations are difficult to find.

Road Markings

White Lines

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

Yellow Lines

Yellow lines are used to mark some form of waiting restriction. There are only two types used –

  • Double lines 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.

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 Authority.
