What is the speed limit for this vehicle combination on a motorway?

Explanation: • 50 mph: No.
• 56 mph: This is technically not the speed limit for this vehicle combination, however as it must be fitted with a speed limiter set to 90 km/h (56 mph) this is its practical limit.
• 70 mph: This would be legal for the truck without a trailer but it is 60 mph when the vehicle is towing a trailer.
• 60 mph: Yes, this is the vehicle's maximum legal speed limit.
