Ch. 5 · Driving Method

On roads where no maximum speed is indicated by signs or markings, you must not drive at speeds exceeding 50 km/h.

[True / False · Medium]

Answer: ✕ False

Explanation

When no maximum speed is indicated by signs or markings, motor vehicles must not drive at speeds exceeding 60 km/h. Since the correct speed is 60 km/h, not 50 km/h, this statement is incorrect.
