Select all that apply: which messages belong to the warning-sign family rather than imposing a regulatory order?

Traffic queues are likely ahead.Ճիշտ պատասխան
A mandatory minimum speed starts here.
There is a risk of ice on the road.Ճիշտ պատասխան
Vehicles are prohibited beyond this point.

Բացատրություն

Likely traffic queues and a risk of ice are hazards about which drivers are warned in advance. A minimum-speed control and a no-vehicles control prescribe conduct, so they belong to the regulatory family instead.
