Without explicit priority signs, an ascending car and a descending lorry meet on a 10% gradient where they cannot pass simultaneously. There is no doubt about the gradient or the distance to passing places. Who has priority?

Correct answer

The car, because it is travelling uphill, except when it can reach a passing place first.

On a steep section, with a gradient of at least 7% and insufficient width for simultaneous passage, the ascending vehicle has priority unless it can reach an established passing place first. Here that is the car. Its priority is not absolute: it must facilitate passage when that exception applies. If the gradient or distance to the passing place is in doubt, article 62 applies.
