Are you one of the truckers parked up on the hardshoulder M4

Are you a trucker parked up on the M4 hardshoulder westbound ? The reason I ask is my son is stuck in heavy traffic and is phoning me asking how far along before traffic clears? Is there any info on the CB ? He’s just flown into heathrow this evening and has taken from 6.30pm , till now 10.50pm to get to junction 6 is he likely to get to Swindon tonight ? Any imformation appreciated.

According to the traffic cams is virtually clear once past reading otherwise crawling
