Traffic lights joining Black Dam Roundabout on A30 can't be seen from within stationary car at line.

Reported via desktop in the Traffic lights (NH) category anonymously at 13:45, Mon 26 September 2022

Sent to National Highways less than a minute later. FixMyStreet ref: 3849633.

The set of traffic lights are very poorly positioned at the Western junction of the A30 London Road, and the Black Dam roundabout (Basingstoke ring road). If your car is stopped at the line in the left hand lane, either waiting to head South to M3 junction 6, or to go straight on Westbound on the A30 Ringway South, you cannot see the nearest set of traffic lights (on the left) from the drivers seat of a car. The lights are positioned too high and are obscured by the roof of the car, and only visible if you lean down to the left. The right hand set of lights can only be partially viewed by turning your head to the right. The real problem, which may well cause a serious accident, is the set of lights that 'are' clearly visible straight ahead and positioned in the central section of the junction can easily be misinterpreted as the lights applying to cars waiting in the left two lanes. The central set of lights are only for those vehicles already on the roundabout but can show green when the lights that should apply (but can't be seen) are at red! If someone reacts (incorrectly) to the central lights changing to green and proceeds, they will risk being hit side on by fast moving traffic on the roundabout. I have driven through this junction on numerous occasions and in several different cars and the lights are obstructed in every case. The issue will have been present since the most recent 'improvement' roadworks were carried out at Black Dam Roundabout.

  • Correction: The traffic lights are at the South 'Eastern' section on the Black Dam Roundabout - problem occurs if 'waiting' to head West, or South to M3 (J6).

  • Thank you for your report concerning traffic light positioning on Black Dam roundabout.

    Recently, we assessed this junction for issues with light positioning. As this roundabout is quite complex that deals with lots of different traffic, it is very difficult to position lights where they cannot be seen by any traffic other than the traffic they are applicable to. We've used hoods and louvres to reduce this issue, but road users will still need to be aware of which lights are relevant to them. As per required specifications for traffic lights, there are primary poles sited at the stop line, which are the ones which some road users may struggle to see in stationary traffic, however there are secondary poles directly opposite the A30 entrance to the roundabout which should be clearly visible. According to our assessment, these meet required regulations, and we haven't identified this location as unusually susceptible to road traffic accidents. However, we have registered your concerns and will continue to monitor this roundabout, and if the situation changes we will take action to ensure road users' safety as appropriate. If you require any further update on this issue our Customer Contact Centre is available 24 hours a day at:
