Weather, Visibility & EmergenciesStandalone practice
The highway patrol has announced that a stretch of state highway is closed because of a blizzard. Your pickup has four-wheel drive and new winter tires. May you drive on the closed road?
Correct answer: No. Once the closure is announced, driving on that road is illegal.
Why
Officials close roads when blowing snow, ice or flooding make travel too dangerous, and rescuers may not be able to reach a stranded driver. Drivers who ignore a closure also put snowplow crews and rescuers at risk. Before a winter trip, check road conditions, for example by dialing 511.
