Check Insurance
Does your current vehicle insurance cover you while collecting roadsigns? It’s possible that your insurance company never considered this possibility when it quoted you your policy. Are you sure that “social, domestic and pleasure” really includes this? If you step back into the road to get that better angle on an accident black spot sign and cause a multiple pile-up, you could end up without a leg to stand on. Nowadays insurers ask you what was the purpose of the last journey before the accident even if you weren’t in the car at the time.
