The primary purpose of the A39 'Roadworks' sign is to provide an early warning of upcoming roadworks. This allows drivers to prepare by reducing speed, increasing their following distance, and widening their observation before they reach the actual work zone, ensuring a safer transition.
Upon seeing the A39 sign, you should immediately start anticipating potential hazards. This means preparing to reduce your speed, increase your following distance, and be extra vigilant. Avoid unnecessary overtaking or sudden lane changes as you approach the work area, especially if visibility, road grip, or road width is affected.
A common trap is treating the A39 sign as a mere suggestion or only reacting when you are directly at the roadworks. You must prepare in advance. Another trap is failing to increase your following distance sufficiently, which can lead to problems if traffic suddenly stops within the work zone.
Not necessarily 'significantly' unless conditions demand it, but you must prepare to reduce speed. The sign is an advance warning. You should reduce speed if the roadworks affect visibility, grip, road width, or if there are vulnerable road users present. Always drive at a speed appropriate for the altered conditions.
You should avoid overtaking or making abrupt lane changes when the A39 sign is displayed, especially if it indicates a reduced safety margin. The focus should be on maintaining a safe speed and position, and being prepared to react to changes ahead, rather than trying to gain an advantage by overtaking.
The A39 sign is often accompanied by sub-panels providing more specific information, such as the distance to the roadworks, the duration, or specific instructions. You might also see signs indicating lane closures, temporary speed limits, or diversions, as well as traffic signals or temporary road markings directing traffic through the work zone.
