Q #356 - You're using a smart motorway. What happens when it's operating?
When a smart motorway is operating, you must follow the mandatory signs on the gantries above each lane, including the hard shoulder. Variable speed limits help keep the traffic moving and also help to prevent bunching.
| Speed limits above lanes are advisory | |
| The national speed limit will apply | |
| The speed limit is always 30 mph | |
