National park bosses are warning outdoor event organisers not to post illegal advertising signs to publicise their events.
The Lake District National Park Authority said its compliance staff recently had to take down some materials in the area.
It is urging event organisers to contact them before putting up any advertising displays, so they don’t fall foul of regulations.
Compliance planner Julie Birkett said: “We have been providing advice for a number of years and the majority of people are aware of the Advertisement Regulations and comply with them.
“However each year there are new events which display signs which are illegal.
“If we are able to identify the organiser we can provide advice and in most cases the signs are removed voluntarily. But in some instances we do serve a formal notice and remove the signs ourselves.”
Planners are particularly concerned about signs on road verges in the national park some of which also advertise retailers and sports events, which they say both look out of place with the rest of the Lake District landscape, and also can be distracting to drivers, resulting in potential road dangers.
A spokesperson said planners accept that the advertisements control regulations are detailed and do appear to be complicated. While most infringements can be solved amicably, offenders have been reminded that they could eventually end up in the courts with the potential for a £2,500 fine.
“To prevent this happening all people need to do is come and talk to us first before they start their promotional activity. That way we can all work together to ensure the events are promoted successfully and legally,” Ms Birkett added.
