Warning Signs
Warning signs often but not always comprise a triangle with a red border, white background and black symbol. As set out in the Traffic Signs Manual (available at Traffic signs manual - GOV.UK) they are used to alert drivers to potential danger ahead. They indicate a need for special caution by road users and may require a reduction in speed or some other manoeuvre.
Appropriate warning signs make an important contribution towards road safety. However, as mentioned in Chapter Four of the Traffic Signs Manual they must be used sparingly. If they are used to warn of road conditions that are readily apparent, this may devalue the signs and reduce their overall effectiveness. Therefore, each request the Authority receives must be considered carefully before deciding whether a sign is appropriate. There is a need for this type of sign to be used consistently.
At locations with dark or complex backdrops, warning signs can be mounted on grey or yellow backing boards to highlight their presence.
Chapter Four of the Traffic Signs Manual contains regulations and recommendations regarding the use of different types of warning signs. These help to identify the various locations and circumstances where different types of warning sign may be appropriate. They also provide specific guidance as to where warning signs are not appropriate.
When assessing a request for warning signs, the Authority must adhere to the Traffic Signs Manual. Additionally, the Authority will consider a variety of factors, which may include:
- the road hazard involved, its relative severity, and how much prior indication there may already be;
- the collision history at that location;
- the speed of traffic along that section of road;
- road conditions and other signage along that road or route – to ensure consistency.
Under the Highways Act 1980, the Highway Authority does not have a duty to provide warning signs. The absence of a warning sign does not negate the responsibility of drivers to drive in accordance with road, traffic and weather conditions.
