“We send our most sincere and heartfelt condolences to his family, for which we know he was deeply devoted to.
“Jaroslaw, you will live in our hearts and minds forever.”
Eyewitnesses told News they were stuck in stationary traffic near the crash for more than three hours and could “see black smoke and flames”.
The motorway shut from junction 36 to junction 39 and reopened fully in the early hours of Wednesday.
