Describe the winding section
Use the approximate length and average character of the curvy part—not the entire journey.
Conditions vary within a route. Check current restrictions, weather and closures separately.

How demanding could this winding road feel?
Estimate the combined effect of curves, elevation, road width, surface, vehicle size and motion sensitivity before choosing the scenic route.

What makes a curvy road harder?
A winding road demands repeated steering, speed adjustment and visual scanning. Long descents can add braking workload, while narrow lanes reduce margin for larger vehicles. For passengers, being unable to see the road ahead can increase motion sickness even when the driver feels comfortable.

Frequently asked questions
What counts as a winding road?
There is no single universal threshold. Here it means a section that needs repeated steering and speed adjustment rather than occasional gentle motorway curves.
Why does vehicle type matter?
Campervans and trailers generally need more space and planning on tight bends, narrow lanes and descents. Exact limits depend on the individual vehicle and road.
Can this predict motion sickness?
No. It only increases the planning score when you report sensitivity and stronger curves. Individual reactions vary and the tool cannot observe the real journey.
