Road markings and signs

Single and double yellow lines

The presence of yellow lines in a road indicates that a waiting restriction is in operation.  The restriction times differ depending on the location.  It is important to read the yellow plates in the immediate vicinity. However, in Controlled Parking Zones ,here are normally no individual sign plates and the restriction times are shown on large signs at the entrances and exits to the zone. 
Double yellow lines indicate that waiting is not permitted at any time, which means literally any hour of the day or night, 365 days of the year, even if there are no post-mounted signs.

Detailed information about road markings and signs is available in The Highway Code.

Requests for single or double yellow lines

Although we receive many requests to install yellow lines, it would be impractical to introduce them at the many locations throughout the borough where they are requested. 

New yellow lines will only be considered in roads where all of the following principles apply:

  • there are no private driveways (except in CPZs),
  • vehicle accessibility is a problem,
  • the road is not wide enough to accommodate parked cars,
  • speeding is not likely to increase due to a lack of parked cars,
  • there is no possibility that parking will be displaced to other locations, 
  • a parking survey has identified parking problems in the area.
