PennDOT Driving in Hazardous Conditions 5

Question 1

In Pennsylvania, at what outside temperature should you be most alert for unexpected ice on road surfaces?

Accepted Answer

Between 25°F and 35°F (-4°C to 2°C)

Answer

The most dangerous range is near freezing — roads may appear wet but be coated with invisible ice, and salt loses effectiveness below about 15°F.

Question 2

When driving in sleet or freezing rain, which surface is likely to be the slipperiest?

Accepted Answer

A shaded section of road under trees

Answer

Shaded areas stay colder because sunlight cannot melt ice there, making them significantly more hazardous.

Question 3

What does it mean when a Pennsylvania highway sign reads 'PennDOT Road Condition: Restricted'?

Accepted Answer

Travel is strongly discouraged except for emergencies

Answer

A 'Restricted' condition means conditions are extremely hazardous and PennDOT strongly discourages all but essential travel.

Question 4

When following a snow plow on a Pennsylvania highway, how much distance should you maintain?

Accepted Answer

At least 200 feet

Answer

PennDOT recommends staying at least 200 feet behind snow plows to avoid flying debris, salt spray, and reduced visibility.

Question 5

When a front-wheel-drive vehicle begins to skid, the front wheels lose traction and the car plows straight ahead. You should:

Accepted Answer

Release the accelerator and allow speed to drop to regain steering

Answer

Lifting off the accelerator reduces speed, which allows the front tires to regain grip and steering control to return.
