A slippery-road warning triangle has a plate reading 'For 2 miles'. What does the plate tell you?
The hazard begins after two miles and ends immediately.
The warned condition extends for the next two miles.✓الإجابة الصحيحة
Drivers must travel at two miles per hour through the hazard.
An alternative route becomes available in two miles.
الشرح
The stated mileage describes how far the warned condition continues along the route. It is not the remaining distance before the slippery section begins, which would use a distance-to-hazard message.
