@HertsPolice we are parked up by barriers on a41 north just off m25 junction. A bad accident by looks of it. Doesn’t feel safe parked by barriers can you make other side single lane?

Another motorist reported it looked like a "bad accident" and said they do not feel safe parked by barriers just off the M25 junction.
