Gantry signs not showing variable speed limits

Reported via desktop in the Sign issue (NH) category anonymously at 13:47, Sat 22 April 2023

Sent to National Highways less than a minute later. FixMyStreet ref: 4473588.

Travelling this morning at around 7.30am between J13 and J15 clockwise on the M25, the overhead gantry signs were not showing any speed limits however the speed cameras were flashing several times to the drivers on the road who were all doing below 70mph. Has there been a technical issue here?

Updates

  • Travelling towards Heathrow approximately J15 and the gantry warning sign was not working this morning, at 6am. I was doing over 50mph so presume had the warnings been in place it would be for 50mph. I was flashed. On the return journey the warnings were on all gantry's but when we looked on the other side there were not on. Just reporting here in case this happened to someone else this morning.
