D. Temporary Signs
(a) Sign required by obstructions on the highway
Road works
There should be a single Traffic Safety Code indicating for roads of all speeds the signs to be used for obstructions and emergencies and the way to use them (paragraph 193) . Instead of Slow an appropriate speed limit sign should be used. Explicit information as the the nature of the obstruction should be given by the first sign. This should be followed by information about the distance to the obstruction and the amount and extent of the carriageway obstructed. Protocol signs and traffic cones should be used on the approach to an obstruction and a sign indicating 'Road clear' after it (paragraph 194). Signs are recommended to indicate loose chippings, wet tar, temporary road surface, ramp, pass either side, look right/left (paragraph 195).
Fewer warning signs of road works should not be put up because the works are of short duration or because the obstruction is moved forward as work progresses (paragraph 196).
Authorities responsible for road works should ensure in advance that their contractors are aware of the Code and they should make it a condition of contract that the correct warning signs are properly erected and afterwards removed. Penalties for breach of this condition should be enforced (paragraph 197).
Alternate one-way working past an obstruction should be controlled by traffic signals where traffic is dense or at extended obstructions; by manually operated Stop and Go signs where traffic is not dense and obstructions are small and of short duration; and, where the above means are not justified, by signs indicating the direction in which traffic has priority. Red and green flags should cease to be used (paragraph 198).
Accidents and emergencies
In the case of accidents or other emergencies a warning should first be placed well in advance of the obstruction. Next the obstruction itself should be very clearly marked (paragraph 199).
When Regulations are made to allow drivers to place on the carriageway an advance warning sign in case of breakdown or accident involving obstruction, a red reflectorised triangle is recommended for this purpose (paragraph 200).
Signs to give advance warning of ice and fog are recommended (paragraph 201).
Highway authorities should be reminded that it is their responsibility to ensure that obstructions on their roads are properly signed and that the signs are not left up after the obstruction has been removed (paragraph 202).
