At a narrow section with no signs or instructions regulating priority, which is not a steep-gradient section, it is known which vehicle entered first. If two vehicles cannot pass each other, which has priority?

Correct answer

entered the narrow passage first.

The vehicle that entered first, under Article 60. If there is doubt about which entered first, priority goes to the vehicle with greater manoeuvring difficulty under Article 62. Steep-gradient sections have the specific Article 63 rule: priority to the ascending vehicle unless it can reach a passing place first. The question excludes that case and any explicit regulation of priority.
